Hydrogen can form one covalent bond.
An atom can make a number of covalent bonds equal to the number of electrons it needs to fill its outer shell
Four covalent, polar, bonds with H atoms in ammonium ion: NH4+ (the same configuration as CH4).
Water molecules have two simple covalent bonds between one oxygen and two hydrogen atoms. Covalent bonds are also known as organic bonds.
The element with an atomic number of 8 is Oxygen. It has 2 electrons in the first shell and 6 in the second, leaving a valence of 2. Oxygen, therefore, can form covalent bonds with only two Hydrogen atoms. This is also known as water.
An element with atomic number 7 (nitrogen) can make a maximum of 3 covalent bonds, while an element with atomic number 16 (sulfur) can make a maximum of 2 covalent bonds. Therefore, when they combine, they can form a total of 5 covalent bonds between them.

Nitrogen forms covalent bonds with hydrogen. In covalent bonding, atoms share electrons to achieve a stable electron configuration. Ionic bonding involves the transfer of electrons from one atom to another to form ions with opposite charges.
Carbon is in Group V. Thus, it needs 4 more electrons so as to achieve the octet structure in its valence shell. As such, carbon has make at most 4 single covalent bonds. The least number of covalent bonds carbon can make is 2 double bonds. We do not see an example of carbon forming 1 covalent bond involving the sharing of all 4 of its valence electrons.
2 covalent bonds: H-O-H. In other words, it makes water.
The bonds between atoms in water molecules are covalent bonds. In a water molecule, each hydrogen atom forms a covalent bond with the oxygen atom by sharing electrons. This sharing of electrons creates a stable structure in the water molecule.
