Answer:

A) None, 0;

B) 2.

The valence electrons of the chemical elements that are bonding and nonbonding are shown in the Lewis structure. The valence electrons are the outermost electrons in an atom’s nucleus. The form of the compound is determined by a variety of methods, including the octet rule, molecular orbital theory, and valence shell electron pair repulsion.

The non-bonding, or unshared, electrons in an atom’s outermost orbit are the lone pair of electrons. The general definition is that they are the single pair of electrons for the atom. In Lewis structures, the non-bonding pair is positioned around the central atom.
