You can determine the number of covalent bonds an element can form by looking at its group number on the Periodic Table. Elements in group 4 can typically form 4 covalent bonds, elements in group 5 can form 3 bonds, elements in group 6 can form 2 bonds, and elements in group 7 can form 1 bond.
The number of covalent bonds an element can form depends on the number of valence electrons it has. In general, elements can form a number of covalent bonds equal to the number of valence electrons needed to reach a full valence shell (usually 8 electrons). For example, element X can form up to 4 covalent bonds if it has 4 valence electrons.
Sulphur has six valence electrons and hence it can form maximum of six covalent bonds as in SF6.
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.
Polonium is a metalloid element and it can form both ionic and covalent bonds. In general, polonium tends to form covalent bonds with nonmetals, and can also form ionic bonds with highly electronegative elements.
Chlorine forms covalent bonds with other nonmetals and ionic bonds with metals.

Metals form generally forms ionic bonds as in salts.Carbon form covalent bonds, for ex.
Chlorine forms covalent bonds with other nonmetals and ionic bonds with metals.
In its pure form as an element, antimony (Sb) is a metal, and it therefore forms a metallic bond rather than a covalent bond.
The octet rule is used to determine how many covalent bonds an element can form. This rule states that elements tend to gain, lose, or share electrons to achieve a full outer valence shell with eight electrons.
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.
Nitrogen is most likely to form three covalent bonds. Nitrogen has five valence electrons and can achieve a full valence shell by sharing electrons with three other atoms. This allows nitrogen to form three covalent bonds in compounds like ammonia (NH3).
HYDROGEN
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.
