No; nitrogen can form single, double, or triple bonds.
Non-polar
Only halogens and members of the oxygen group can form diatomic molecules joined by a single covalent bond.
You are thinking of iodine. It is a way to test for starch.
A carbon atom can form 4 single covalent bonds
They will form seven bonds along with all the other elements in that column on the periodic table.

Iodine typically gains an electron to form a -1 ion.

Carbon is important to life because it can form complex molecules. This is because because of its ability to form many bonds. Carbon typically has four single bonds, two double bonds, one triple and one single bond, or one double and two single bonds. Due to this extensive boding, carbon can form large molecules that are necessary for the existence of living things.
You are thinking of iodine. It is a way to test for starch.
Like all other halogens, usually one. Like all elements in or below the third row of the periodic table, it is able to make additional bonds in some cases, though those are rare. One example is the triiodide ion, where one iodine makes two bonds.
A carbon atom can form 4 single covalent bonds
Carbon has four valence electrons, each of which can be shared to form four single bonds. This means that it is possible to have two double bonds.
hydrogen, oxygen, fluorine, bromine, iodine, nitrogen, and chlorine are all nonmetals. nonmetals form covalent bonds.
