I anm definitely not a halogen. But if all you knew about me
Dmitriy789 [7]

The periodic law is a law relating the properties of the element with their

atomic numbers.

The element is <u>potassium, K</u>.

Reason:

By atomic mass, potassium is 39.10 g, while argon is 39.10 g.

Going by the atomic mass alone, potassium should come before argon in

the periodic table and therefore should be an halogen and not an alkali

metal.

However, the number of protons in the potassium is 19, and therefore larger

than the number of protons in argon, which is argon.

Therefore, the element is <u>potassium, K</u>.
