WebJan 30, 2024 · The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. When discussing the octet rule, we do not consider d or f electrons. Only the s and p electrons are involved in the octet rule, … WebA positive ion or cation is an atom that has lost electrons. Nonmetals tend to gain electrons and become anions. For example, in Fig. 2.22 A, a neutral oxygen atom (O), with eight protons and eight electrons, gains two electrons. This gives it two more negative charges than positive charges and an overall charge of 2–. WebAug 15, 2024 · One example is hydrogen, which may gain (H-) or lose (H +) an electron, forming hydride compounds such as ZnH 2 (where it is an anion) and hydron compounds such as H 2 O (where it is a cation). Elements in group 18 of the periodic table – the “noble gases”, tend not to form ions due to the arrangement of their electrons which makes … diamond dr trucking llc
