Hello
your best answer,
Electronic configuration of hydrogen is 1s and to attain the stability i.e., to acquire the electronic configuration of nearest noble gas helium (1s) hydrogen atoms share their single electron with each other Therefore, hydrogen exist in diatomic and not monoatomic hydrogen.

we know,
every atom has tendency to achieve the configuration of its nearest inert gas.
also we know , Hydrogen has only one electron in its 1s-orbital.so, it has tendency to achieve stable inert gas configuration of Helium, hence, two Hydrogens make covalent bond by sharing of electrons. So, it exists as diatomic molecule and it is called dihydrogen.
