hope this helps you...

Answer 2

Answer:

The distribution of electrons in an atom having atomic number 18 is, the first orbit closest to the nucleus has 2 electrons, the next orbit consistences of 8 electrons and the last orbit which consists of 8 electrons.

Explanation:

The element having atomic number 18 in the periodic table is "Argon", which is considered as a non-reactive element as it has no extra electron or lack of electrons, hence not reacting with any other elements.
