Achemical bond formed between two atoms share electrons is called a(n) a. 8 valence electrons b. no valence electrons c. 7 valence electrons d. 17 valence electrons

The wording of this sentence makes no sense. A chemical bond formed between two atoms sharing electrons is called a molecular bond. The question is likely asking about the amount of valence electrons required to form a bond. We call this the “octet rule”. All atoms have a propensity to require 8 valence electrons (an octet) in order to be stable. However principles of the octet rule are followed in both ionic and molecular bonds.
