Question

Which of the following statements is correct when describing the interactions that occur between individual chlorine atoms as they approach each other and form Cl2?

a. As two chlorine atoms approach each other, each atomic nucleus starts to attract the other's electron, which raises the potential energy of the system. b. As attractions increase, so do repulsions between the nuclei and between electrons. c. At some internuclear distance, the maximum attraction is achieved in spite of the repulsions, and the system is at its highest energy. d. The mutual attraction of nuclei and electron pair in the two chlorine atoms constitutes the ionic bond. e. none of these

Explanation / Answer

only option b) is correctAs attractions increase, so do repulsions between the nuclei and between electrons.

rest all are wrong

option a) is wrong because potential energy decreases

c)because system energy lowers down not rises

d) is wrong because Cl2 is a covalent bond not ionic
