Which of the following describes the share of a non-bonding electron pair on a N molecule with an O atom resulting in a nitrous oxide molecule. The stable balance of attractive and repulsive forces between atoms when they share electrons is known as covalent bonding.

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 15. K 2 S f. Take the difference of electronegativity between the two atoms.

A Ammonia contains the nonmetals nitrogen and hydrogen. 3 and 16 3. In a polar covalent bond A both atoms in the bond have the same level of electronegativity.

B one atom in the bond must have higher electronegativity than the other atom. When electronegativity difference is greater than 04 and less than 18 then bond between the two atoms is a polar covalent bond. Draw the electron dot structure of the polyatomic boron tetrafluoride anion BF 4-.
