Question

what is the definition of a chemical bond?
o a mutual attraction between the nuclei and electrons in two different atoms
o a mutual repulsion between the nuclei and electrons in two different atoms
o a mutual repulsion between the nuclei and electrons in a single atom
o a mutual attraction between the nuclei and electrons in a single atom

Explanation:

A chemical bond is formed by the mutual attraction between the nuclei and electrons of two different atoms, which holds the atoms together. Repulsion does not form a bond, and it involves two - atom interaction rather than a single - atom one.

Answer:

a mutual attraction between the nuclei and electrons in two different atoms
