Question

THE ELEMENTS HAVING EIGHT VALENCE ELECTRONS KNOWN AS

Answer 1

Answer:

Any element in group 18 has eight valence electrons (except for helium, which has a total of just two electrons). Examples include neon (Ne), argon (Ar), and krypton (Kr). Oxygen, like all the other elements in group 16, has six valence electrons.

Answer 2

Answer:

NOBLE GAS

The octet rule is a chemical rule of thumb that reflects the observation that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
