Common misconception about rocks and minerals Rock - an aggregation of one or more minerals or a mixture, where the properties of each mineral are retained. Minerals - naturally occurring inorganic solids which possess an orderly internal structure, a definite chemical composition and characteristic physical properties. Therefore, each element have a their own unique type of atoms. It is only the electrons in the outer shell which is involved in bonding B. Bonding occur when atoms of 2 or more elements join to form a compound. Octet rule - atoms combine in order that each may have electron arrangement of a noble gas, with the outer energy shell containing 8 electrons atom can either gain, lose or share electrons with one or more atoms.
Valence electrons are electrons involved in the bonding process.
H has 1 valence electrons 1. One or more valence are transferred from one atom to another, resulting to attraction of oppositely charged particles. 1. attract 7 more electrons to fill up the third shell 2. eject or kick out the one electron in the third shell, eliminating that shell. That leaves it with two shell, both of which is completely filled up. It will require less energy to kick out the one electron in the third shell than to attract 7, resulting to the atom having 10 electrons.
