An octet is formed via ionic bonding when one or more valence electrons are transferred from one atom to another. An octet is formed via covalent bonding when valence electrons are shared between atoms. True or false?

The second statement is true.

Explanation:

"An octet is formed via covalent bonding when valence electrons are shared between atoms" this statement is true.

The ionic bond is formed when there is an overall transfer of valence electron among the two atoms that generates two oppositely charged ions. One atom loses electrons forming positively charged cation, other accepts the electrons forming a negatively charged anion hence octet can not be formed In covalent bonding there is sharing of electrons hence an octet is formed

∴ The second statement is true.
