In which of the following pairs attractive force work?

\mathop {{N_A} - {e_A}}\limits_{\text{I}} ,\mathop {{N_A} - {e_B}}\limits_{{\text{II}}} ,\mathop {{N_B} - {e_A}}\limits_{{\text{III}}} ,\mathop {{N_B} - {e_B}}\limits_{{\text{IV}}} ,\mathop {{N_A} - {N_B}}\limits_{\text{V}} ,\mathop {{e_A} - {e_B}}\limits_{{\text{VI}}}

Here,

N_A

and

N_B

represent two nuclei and

e_A

and

e_B

refer to electrons surrounding

N_A

and

N_B

nuclei.

View answer and explanation

Correct option: C

I, II, III and IV

Option C (I, II, III and IV) is correct because attractive forces exist between nuclei and electrons, specifically between

N_A

and

e_A

N_A

and

e_B

N_B

and

e_A

, and

N_B

and

e_B
