Ionic Minerals

Question: Can you list 5 minerals held together by ionic bonds, and 5 minerals held together by covalent bonds? My homework that I just can't seem to find the answers to. And yes this is a GHAMAS homework assignment from Mr. Sams. I guess I'm not the only one looking for the answers.

Answer: is this for mr. sams kim

Question: How are minerals ionic compounds?

Answer: Most minerals contain silica or different metals bound to oxygen and other non metals. The bonds between metals and non-metals are classified as ionic bonds. Most covalent bonds occur between non-metals and non-metals, or non-metals and metalloids.

Question: Can you recommend a good liquid ionic mineral supplement for a guy on a budget? I'm beginning to experiment with getting my health and mind in order. I know minerals are important, and alot of studies have gone into liquid forms. Does anyone know of a good product that isn't going to bankrupt me before I get healthy?

Answer: 1. When you take a mineral tablet, it is a liquid in your digestive system after it dissolves. 2. Minerals are cheap. 3. Taking all your minerals together will waste most of them, as the ions all compete for the same limited number of absorption sites in your small intestine. 4. All mineral supplenemts are ionic once you start to digest them.

Question: Which of the following factors control how minerals weather? 1. Whether the mineral has ionic or covalent bonds 2. Whether the rock contains quartz or calcite 3. The temperature at which the original minerals formed 4. Whether a mineral typically crystallizes early or late in Bowen's Reaction Series 5. All of the above

Answer: the temperature the rock formed.

Question: Discuss your understanding of minerals being ionic compounds.?

Answer: Graphite and diamonds are not ionic compounds, yet are still polymorhphs of carbon. Most substances (including minerals which have specific crstal structures, chemistry, etc), other than pure elemental forms, are ionic compounds...

Question: How do i determine whether a compound(such as a vitamin/mineral) will be ionic or covalent based on its formul? How do i determine whether a compound (such as a vitamin/mineral) will be ionic or covalent based on its formula?

Answer: Organic(carbon ) based will generally be covalent, while metallic based are ionic. This is just a generality thoigh. But it will be that way most of the time.

Question: how and why minerals are classified by their ionic nature?

Answer: Humans like to classify things into related categories, as it helps us to understand and remember. Metals were grouped according to their reactivity with acids, water, etc. There seemed to be 'periodicity', ie. a pattern, that metals made, so the metals were grouped accordingly. This gives us a periodic table that can be used, rather than a bunch of elements randomly placed that don't impart relatedness. See http://www.chemtutor.com/perich.htm#pps for a brief description and see a fun history at http://web.fccj.org/~ethall/period/period.htm

Question: Geochemists only: why do felsic minerals melt at lower temps than mafics? It doesn't seem right since the high silica minerals have lots of strong covalent bonds, and the mafics have some weaker ionic bonding.

Answer: You have it backwards Covalent bonds are weak bonds like sugar they melt quickly Ionic bonds are very strong like salt and melt at high temps

Question: Essential Vitamins & Minerals business offering thru internet, anyone interested? This multivitamins & minerals are build in ionic liquid form. Easy to consume.

Answer: Nope. Sorry.

Question: People who know about Ionic Potential? I have a geomorphology test on Monday and i am wondering how Ionic Potential explains the selected loss of minerals dring weathering. Thanks guys!

Answer: Weathering would imply rain and any other influence of water on the minerals. The minerals would be more or less soluble, hence prone to dissolving and running off, dependent upon their ionic potential, their characteristic attraction for other charged particles such as the positive and negative ions in water.

Question: Question about bonds in minerals? I am very new to physics and chemistry and would appreicate some help on the following: 1) Why is it that minerals display a combination of bonds not purely ionic or covalent? 2) Is it possible to have something that is purely ionic or covalently bonded? If so please quote some examples. 3)Why is it stated that quartz is mostly covalently bonded?

Answer: 1) most chemical bonds are in between ionic and covalent but not strictly one or the other. the only strictly covalent bonding i can think of is bonding between the same elements (like O2 for instance). that is because bonding often has to do with electronegativity. a more electronegative nucleus has a greater tendency of taking electrons. therefore, when it is bonded with a not so electronegative nucleus, the shared electrons would spend more time with the electronegative nucleus, thus there is a mostly ionic bond that forms. eg. NaCl (Cl is more electronegative than Na, so electrons will spend more time around Cl) 2) I can't think of a purely ionic bond. as i've said, NaCl is mainly ionic, but i can't say that there is no sharing of electrons involved. as for a strictly covalent bond, O2, F2, H2 and other bonds between same elements are covalent since electronegativity is equal, so the electrons are equally shared. 3) quartz is a covalent network crystal. what happens is the silicon has low electronegativity, so its electrons spread out and is single bonded to four oxygen atoms. each oxygen is then bonded to other silicon and it forms a network of covalently bonded atoms. see my source for more details.

Question: question about bonding in minerals? 1) Why is it that minerals display a combination of bonds not purely ionic or covalent? 2) Is it possible to have something that is purely ionic or covalently bonded? If so please quote some examples.

Answer: Answer 2 Bonds tend to have mixed characteristics not completely one or the other. The property is influenced by the form of the environment : solidstate, polar solvent etc. Ionic bonds require a donor atom with weakly bound electron far from the nucleus (eg lower Group1 Cs) an acceptor atom that will bind the electron tightly close to the nucleus (eg upper Group 8 F) Thus CsF in a gaseous state or polar solvent is almost purely Ionic. The Covalent Bond requires that both atoms bind the electrons tightly as in CCl4. You should look at the other bond types as well: dative covalent; metallic, hydrogen; Van der Waal for a full explanation of mineral bonding especially Clays and Permutite minerals. Answer 1: When the earth formed and cooled certain elements were pulled to the centre of the earth and formed metallic bonds. These are in-accessible to us. Other active elements formed strong bonds quickly or paired up as in N2. Others formed bonds slowly. Geologists tend to study minerals of economic importance formed and concentrated by water processes in sedimentation or hydrothermal spots near volcanoes and sea floor spread. You will need to include all this information and arguments in your answer to gain full marks. CopyLeft:RufusCat

Question: As mineral groups are categorised on anions such as SO4^2- do they mostly consist of ionic bonds?

Answer: Yes, because the contain a -ve they must consist of an ionic bond to a cation. How ever if you do not include the ionic bond from the cation they are mostly covlent. S=O and S-O- are not ionic bonds.

Question: How would you use these science terms in a sentence? Im doing homework and i have to use all these words in a sentence. I need one sentence for each word. Thanks for your help. Atom Proton Neutron Electron Element Compound Atomic Number Atomic Mass Isotope Ionic Bond Covalent Metallic Bond Minerals Silicate Any of these that you can think of would be great. Thanks again

Answer: Well, as you can use the word in any sentence it could be anything like: I don't know what an atom is. It IS a sentence, i think you should have been told a bit clearer what type of sentence to use. I would write the definition of each, making a scientific sentence that would impress your teacher. Just abbreviate the definitions and put them in your own words. For eg. - An atom is the smallest piece of an element. Do the same with the others. Hope that helped, this took a while to type. hopefully ill get best answer :) Good luck

Question: the mineral spinel is an ionic compound containing only the elements Mg,Al,O. simplest formula is probably? a.MgAlO3 b.Mg2AlO4 cMgAl2O4 d.Mg2Al2O3 e.Mg2AlO3 please explain why.

Answer: Mg++ Al+++ O-- Multiply the number of Mg ions by 2 and the number of Al ions by 3 - this must be equal to the number of O ions times 2. c is the answer because 1 x 2 + 2 x 3 = 8 = 4 x 2. None of the others balance.
