Document Summary
To obtain stability, they need to either gain, share or lose electrons. The exception to this rule is hydrogen, which only needs 2 electrons to obtain stability. Ionic bonds result from the transfer of electrons. Cations are positively charged and anions are negatively charged. Cations result from losing electrons while anions form from gaining protons. Covalent bonds result from electron sharing between atoms. Remember protons= charge +1, neutrons= charge +0 electrons= -1. An atomic number is the number of protons in the nucleus of an atom and it determines a chemical"s nature. It is above the element while the atomic weight is below the element. While the number of protons to an element will remain the same, the number of neutrons can change. Minerals are naturally occurring, inorganic, crystalline solids (ex. Crystalline structure is the physical characteristics of a mineral. Minerals can phase shift between liquid solid and gas.
