Question

The atomic number of an element X is 12.
(a) What must an atom of X do to attain the nearest inert gas electron configuration?
(b) Which inert gas is nearest to X?

Answer 1

Answer:

element X is magnesium

a. it must lose 2 electron.

b. neaon is nearest to X

Answer 2

Neon is the Nearest Inert Gas

Explanation:

• a.) An atom of X must lose its two electrons to attain the nearest inert gas electronic configuration.

• b) After losing two electrons, it will have 10 electrons with electronic configuration 2,8 which represents neon gas. So, Neon gas is the nearest inert gas to X.
