Which elements on the periodic table fulfill the octet rule

Noble Gases

Explanation:

The Noble Gases have a full valence shell of 8 electrons. They are stable in that sense.

beta decay is the answer

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
