Q. Two lithium nuclei in a lithium vapour at room temperature do not combine to form a carbon nucleus because
A) Carbon nucleus is an unstable particle
B) It is not energetically favourable
C) Nuclei do not come very close due to Coulombic repulsion
D) Lithium nucleus is more tightly bound than a carbon nucleus
Explanation
(c) Lithium nucleus and carbon nucleus are positively charge. According to coulomb law same charge repal each other. So, nuclei do not come very close.
