Question

what is octate rule and covalent rule

Answer 1

Answer:

OCTET RULE. The atoms that participate in covalent bonding share electrons in a way that enables them to acquire a stable electronic configuration, or full valence shell. This means that they want to acquire the electronic configuration of the noble gas of their row. Obviously the name of this rule is a misnomer.

Answer 2

The Octet Rule requires all atoms in a molecule to have 8 valence electrons--either by sharing, losing or gaining electrons--to become stable. For Covalent bonds, atoms tend to share their electrons with each other to satisfy the Octet Rule. ... Phosphorus needs to gain 3 electrons to fulfill the Octet Rule.
