Question

Electronic configuration of Ar is 2,8,8. a) Does it take part in chemical reactions or not? Why?

b) Which among the following elements undergo chemical reactions forming

compounds?. Give reason

i) Ca – 2,8,8,2 ii) Ne - 2,8

iii) Kr - 2,8,18,8 iv) S - 2,8,6

c) The attractive force that holds together the atoms in a molecule is known as​

Answer 1

Answer:

mark it as the brainliest answer

Explanation:

a) No, Argon never take part in an chemical reaction as it has octate electronic configuration i.e. it has complete M shell by 8 electrons. So electrons can be donated or excepted by it.

b) Ca- 2,8,8,2 and S- 2,8,6

These two elements will undergo chemical reaction to form compounds because Ca can done it's two valence electrons and S can accept two electrons go be stable and become ions, that will form ionic compounds.

c) The attractive force that holds together the atoms in a molecule is the electrostatic force of attraction.
