Answer 1

Answer:

HELLO PLEASE LIKE MY ANSWER DEAR ⚡

Explanation:

Group 18 Elements. The Group 18 elements include Helium(He), Neon(Ne), Argon(Ar), Krypton(Kr), Xenon(Xe), and Radon(Rn). They are referred to as noble gases or inert gases. This means that these elements are chemically inert and do not take part in any reaction.

Answer 2

Explanation:

The Group 18 elements include Helium(He), Neon(Ne), Argon(Ar), Krypton(Kr), Xenon(Xe), and Radon(Rn). They are referred to as noble gases or inert gases. This means that these elements are chemically inert and do not take part in any reaction.

Electronic Configuration of Group 18 Elements

The general configuration of the valence shell is ns2np6. The exception to this is helium. It has the configuration of 1s2. As they have the octet configuration in their valence shells already, they are quite chemically inert. they have the valency of zero.

The Occurrence of These Elements

All of these elements occur in a free state in the atmosphere. Apart from Radon, every other noble gas exists in the atmosphere. Argon alone constitutes 0.93% of the total atmosphere. We can prepare this element by the fractional distillation of liquid air. We can find neon, helium and argon in certain water springs as disintegrated gasses. Also, we can obtain Radon by the decay of radium and thorium minerals
