NSM 1400 Chapter Notes -Magnesium, Atomic Number, Ionic Bonding
Document Summary
Atoms: atoms- smallest particle that makes up matter and cannot be split up chemically any further, within an atom there are protons, neutrons, and electrons. Compounds: yes, because most minerals have atoms that contain 2 or more elements, note: some minerals can be made out of atoms that only have one element, ex: diamonds, gold, sulfur, copper. Atoms & bonds: some atoms bond to make the electrical charges more stable by lowering the total energy, octet rule- atoms will gain, lose, or share electrons up until they are surrounded with 8 valence electrons. A positive ion loses electrons and a negative ion gains electrons: covalent bond- when atoms share electrons, metallic bond- electron sharing which causes electrons to move freely from one atom to another. Iron: calcium, sodium, potassium, magnesium, note: oxygen and silicon are the most common elements found on earth"s crust, silicates: the most common mineral group. Minerals- non renewable: categories of natural resources:
