Minerals is a naturally occurring substance that is solid. A mineral must occur
naturally, must be inorganic, must be a solid, must be
in an orderly internal structure, must have a chemical composition that vary with specified limits. Some of the types of minerals are Adelite, Braunite, Fluorite, Cerite, and the most common mineral, Silicates. Minerals can be described by various physical properties which relate to their chemical structure and composition.
An Atom is the smallest particle of matter that contains the characteristics of an element. All elements are made of atoms. The central region of an atom is called the nucleus and the nucleus contains protons and neutrons. Protons have positive electric charges. Neutrons are equally dense and have no electrical charge. Atoms have the same number of protons and electrons.
Atoms that have the same number of protons but different numbers of neutrons are called isotopes. Isotopes are variants of a particular chemical element. Isotopes of the same element are labeled mass number and with the element’s name and symbol. The total mass of the atom is called the mass number and the proton and neutron each have a mass is just a little bit larger than the atomic mass unit.
There are different types of chemical Bonds such as Ionic Bonds, Covalent Bonds, and Metallic Bonds. Ionic Bonds form between positive and negative ions. Opposite charged ions are attracted to each other and form a crystalline compound. A Covalent Bonds forms when atoms share electrons. The Bonding in Covalent compounds appears in properties that are different from the ionic compounds.
Metallic Bonds form when electrons are shared by metal ions. The sharing of an electric pool gives metals their characteristic.
There are Four major processes that Minerals form Crystallization from magma, precipitation, changes in pressure and temperature, and formation from hydrothermal solution. Minerals that form Crystallization from magma are usually rich in iron, calcium, and magnesium. As minerals continue to form, the composition changes. Minerals that are rich in sodium, potassium, and aluminum form.
Precipitation is also one of the way minerals can form. In ponds, oceans...etc. may contain dissolved substances. If the water evaporates some of the dissolved substances can form minerals. The changes in water temperature can also cause dissolved material to precipitate out of a body of water. The Minerals are then left behind.
Pressure and temperature can form form two types of minerals, including talc and muscovite. These two form when minerals are exposed to changes in pressure and temperature. When a mineral recrystallizes while it’s solid it’s because an increase in pressure. The atoms are just being rearranged to make more compact minerals. In these conditions new minerals form, and are stable at the new temperature.
hydrothermal solutions are when a mineral forms under a hot mixture of water with dissolved substances. This has temperature between about 100 C and 300 C. There is also Fossil hydrothermal solutions and they can be studied. Quartz and pyrite can form when some cool and some elements combine in them. Hydrothermal solution form in many processes.
Minerals are also important for our body is helps with building bones and regulating your heartbeat. Eating a wide variety of foods is the best way to get minerals in our body that we need. For our body when we are producing skin, muscle, and Bone and intimate red blood to carry out nutrients and oxygen we need minerals in our body. Minerals are considered to be an essential nutrient. Minerals play a lot of roles in our body that help us.
There is mineral groups based on their composition. such as: Silicates, Carbonates, Oxides, sulfates and sulfides, Halides, and Native elements. Silicates is a compound that has anionic silicon compound. Carbonates is a salt of carbonic acid. Oxides is a chemical compound that has at least one
Hunter 1 Gypsum February 24, 2014 Science Gypsum is a mineral with no original discoverer, though the ancient egyptians were the first to take advantage of its wide range of uses. Even though the average american has never even heard of gypsum, every year over 15 million tons of gypsum are used. Gypsum is around you basically at all times, from the plastic cups in your kitchen, to the toothpaste in your bathroom, to the plaster on your walls. It is used in plaster(also known as drywal…

An atom with a net electric charge due to the loss or gain of one or more electrons. 4. What is a cation? An atom with a net positive charge 5. What is an anion? An atom with a net…
level of an atom. They determine how an atom will react in a chemical reaction. 3. A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. An ionic bond is the bonding between a nonmetal and a metal, that occurs when charged atoms attract after one loses one or more of its electrons,and gives it to the other molecule. 4. Carbon. 5. Carbs, lipids, proteins, and nucleic acids. 6. Nutrients. Water, proteins, lipids, carbs, minerals, and vitamins…

16-- Mining 1. mineral: elements or compounds of elements that occur naturally in Earth’s crust; have precise chemical compositions; metallic or nonmetallic ore: a rock that contains a large enough concentration of a particular mineral to be profitably mined and extracted; high/low-grade ores 2. electrostatic precipitators… 3. Hydrothermal process: involve water that was heated deep in Earth’s crust; water seeps through cracks and dissolves certain minerals in the rocks; minerals are then carried…

CHEMISTRY SUMMARY Atoms are the basis of chemistry. Atoms are the smallest particles of an element that can take part in a chemical reaction and cannot be destroyed without losing its chemical identity. Atoms are composed of three fundamental particles called protons, neutrons and electrons. An atom consists of a small central nucleus, which contains the protons and neutrons. Around the nucleus are electrons, which continuously surround the nucleus (2, 8, 8, 18, 32). Protons are positively charged…
Minerals By: Taylor shields Hi! My name is Gem. I have just been discovered by lady scientist Taylor Shields. I am the first every gem to be found on earth. No one knows this, but my family of 1,000,000,000 lives under the surface of the earth. Oh and don’t forget about uncle Bob, so that’s 1,000,000,001. There’s more to mention but it’s too long to say. Now I’m going to list some things about gems! Gems hardness is 8. The other name for gem is Topaz. The most valuable gems are yellow…
