Question

19. The electronic configuation of the atoms Pand
Q are given as P=2,8,1; Q=2,8,7. What type of
chemical bond formed between P and Q​

Answer 1

Answer:

P electronic configuration ( 2,8,1)

So, the atom P is sodium as it has atomic number 11.

Q electronic configuration ( 2,8,7 )

So, the atom Q is Chlorine as it has atomic number 17.

The chemical bond formed between P and Q is iconic bond.

Hope this helps you.

Answer 2

Ionic Bond

Explanation:

P=2,8,1,(metal)

Q=2,8,7(non metal)

$Na^++Cl^-\rightarrow NaCl$

The electronic configuration of P is 2,8,1 so it can easily donate one electron to complete its octet and thus it behaves like a metal.

The electronic structure of Q is 2,8,7 so it tries to get one electron to complete its octet and behaves like a non-metal.

Since one electron is donated by P and one electron is gained by Q so, the ionic bond will be formed between P and Q. Ionic bond is also called as electrostatic bond because it is formed due to attraction between two opposite charges that were developed due to loss and gain of electrons
