Mineral Naturally occurring. Definite chemical composition that may vary within specified limits. Chemical compounds composed of atoms of various elements.
Minerals are chemical compounds composed of atoms of various elements.
Bonding is the result of electrical forces between atoms. During bonding an atom seeks to fill its outermost energy- level shell. Electrons involved in bonding are called valence electrons. Atoms of the same element with different numbers of neutrons are called isotopes of that element. Each mineral has its own unique crystalline structure.
