Answer:

The dihydrogen molecule is held together by a covalent bond.

Explanation:

And a covalent bond is a region of high electron density between 2 positively charged atomic nuclei such that internuclear repulsion is minimized and a strong chemical bond results.

This echoes early ideas of chemical bonding in which ionic bonding results from the transfer of electrons between atoms to give positive and negative ions, and covalent bonds that result from the sharing of electons between 2 nuclei.
