Answer:
The correct answer is both atom in a bond have similar electronegativity thus neither atom is willing to transfer their electrons.Instead the atoms both share electrons to satisfy the octet rule.
Step-by-step explanation:
Two atoms participate in the formation of covalent bond whose electronegativity is similar.
Both atoms donate equal number of electron to form electron pair which is shared equally by the two atoms to satisfy the octet rule.
Covalent bond formation occur by sharing and pairing of electrons .
