Question

which element has zero valency in which group of the period table have they been placed also give their two example

Answer 1

Answer:

Hi there.

Explanation:

Answer: Noble gas have valency 0 because these elements cannot loose or gain electrons. Noble gas are located in the far right of the periodic table and we're previously referred to as the inert gas due to the fact that their valence shells (octets) make them extremely non-reactive. Some of the examples of noble gas are:-

1. Argon.

2. Neon.

Answer 2

Noble gases have valency 0 because these elements cannot loose or gain electrons. The electrons are fully filled in the sub-shells of these elements. hence, the valency of these elements is 0. These elements belong to the last group of periodic table which is Group 18.
