Answer 2

Answer:

the tendency for items have 2 electrons in their outermost shell by interacting with others items through electron sharing or transfer is known as duplet rule.

if an atom has 2 electrons in it's outermost shell then it is called duplet rule and if a 8 electrons in it's outermost shell than it is called octet rule .
