Noble gases are the most reactive elements on the periodic table. a. true b. false

The given statement is false .

Explanation:

Noble gases are least reactive elements in the periodic table. Noble gases have fully filled stable electronic configuration which the reason of their inert and lest reactive nature.

For example : Helium. Neon, argon etc.

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).
