Respuesta :
A single hydrogen atom can form one covalent bond. A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. The atoms share valence electrons, which are in the atom's outermost shell. Hydrogen has one electron to share.Hydrogen has a 1s valence subshell, which can hold a maximum of two electrons. Hydrogen covalently shares this single electron with other atoms needing extra electrons to fill their valence shell.
Hydrogen can form only one covalent bond if each of its unpaired electrons participates in one bond.
Further explanation:
Chemical bond is formed by the attraction of atoms or ions. Due to electronegativity, atoms are able to attract electrons in a chemical bond. The chemical bond is also formed with the help of valence electrons in an atom. The bond forms should obey the octet rule.
The covalent bond is the bond formed by mutual sharing of electrons between the bonded atoms. Covalent bonds are formed by sharing one or more electron pairs. They are also called molecular bonds.
The electronic configuration is the arrangement of electrons in orbitals shells and subshells. It is mainly determined by the atomic number of the atom in periodic table.

Hydrogen is not an electronegative atom. Due to the presence of one valence electron in hydrogen, it sometimes forms covalent bond with other atoms.
Hydrogen has a 1s valence subshell, which can hold a maximum of two electrons. It has one valence electron in its outermost shell that pairs with one electron of any other element and completes its duplet. Also, hydrogen covalently shares its single electron with other atoms needing extra electrons to fill their valence shell.
Therefore, hydrogen can form only one covalent bond, by pairing its only electron with another unpaired electron of another atom.
