Look at the valance number at the top of every family of elements. For example; looking at column 4A, the carbon family, I see 4 valance electrons signified. This means that 4 electrons are needed to fill the outer shell to the octet state. So I know that carbon can form 4 covalent bonds.
A carbon atom can form 4 single covalent bonds
Nitrogen can form three covalent bonds when it has no negative charge.
A single carbon atom can form a maximum of four covalent bonds. This is because carbon has four valence electrons available for bonding.
Single, double, and triple covalent bonds
The number of covalent bonds an atom can form is determined by the number of valence electrons it has. Atoms will typically form covalent bonds by sharing electrons to achieve a full outer electron shell, following the octet rule (except for hydrogen and helium, which follow the duet rule). An atom can form as many covalent bonds as needed to fill its valence shell.

It would form a nitrogen atom because Nitrogen is a nonmetal, and covalent bonds occur when a nonmetal bonds to another nonmetal.
Carbon form generally covalent bonds; ionic bonds are rare.

If it bonds with a metal then its ionic. if it bonds with a nonmetal then is covalent.
An oxygen atom with a negative charge can form two covalent bonds. This is because oxygen normally forms two covalent bonds to achieve a stable electron configuration, and the negative charge does not affect its ability to form bonds.
You can determine the number of covalent bonds an atom will form by looking at its valence electrons. The number of electrons needed to achieve a full outer shell (octet) will determine how many bonds it can form. Main group elements typically form bonds so that they have 8 electrons in their outer shell, while elements from transition metals may form variable numbers of bonds.

It depends on the element Following what one might call "normal" valence an atom such as carbon can form up to 4 bonds. But in some compounds, such as sulfur hexafluoride and atom can bond with as many as six other atoms.
