Answer

Brief Explanations:

Electronegativity increases across a period and decreases down a group in the periodic table. Boron is the least electronegative among the given elements as it is further left on the periodic table compared to the others. In a covalent bond, atoms share electrons to achieve a stable electron - configuration. For most atoms (except hydrogen), this stable state is achieved when they have 8 valence electrons, known as the octet rule.

Answer:

  1. A. boron
  2. C. 8
