Answer :
Answer:
D. almost all atoms strive to have eight valence electrons.
Explanation:
The octet rule is a chemical rule of thumb that states that the observation that elements tend to bond in a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
Exceptions to this rule, This octet rule is only applicable to main group elements but there are many molecules that do not obey this octet rule.
These molecules are divided into two types: unstable intermediates; that react so as to attain stability, and stable molecules that follow other electron counting rules.
