How would you define a bond?

Answer 1

#"The modern covalent bond is conceived to be a........"#

The modern covalent bond is conceived to be a region of high electron density between 2 positively charged nuclei, such that internuclear repulsion is negated and a net attractive force results.

The given definition harks back to the ideas of covalent and ionic bonding to which we are first introduced in Chemistry. Covalent bonding results from the sharing of electrons between nuclei, whereas ionic bonding results from the transfer of electrons between nuclei to give discrete positive and negative ions, which are electrostatically attracted.
