Varies...usually 2, like oxygen, but it can expand its octet and form up to 6 (like in H2SO4...)
Each hydrogen can form one bond with selenium. Each selenium atom can form two bonds, one with each hydrogen (2 hydrogen atoms total).
Germanium, metalloid with a similar structure to silicon- 4 covalent bonds per germanium atomPhosphorus, the most familiar form is white phosphorus which is molecular, consisting of P4 units, each P atom has 3 covalent bonds, other allotropes are not discrete molecules but all have 3 covalent bonds per P atomSelenium This is molecular in Se8 rings each Se atom has two covalent bondsChlorine this is a diatomic gas with a single covalent bond

A carbon atom needs four electrons to have a full outer shell so I guess it can form a maximum of four bonds.
Nitrogen can form a maximum of three single covalent bonds, one with each of its three 2p electrons.
In its elemental form, selenium typically forms two covalent bonds. Selenium has six valence electrons in its outer shell, so it can share these electrons with other atoms to form two covalent bonds.
Selenium can form two bonds with hydrogen.
Each hydrogen can form one bond with selenium. Each selenium atom can form two bonds, one with each hydrogen (2 hydrogen atoms total).
Selenium can form two bonds with hydrogen.
maximum of five single covalent bonds as in PCl5
Nitrogen can form three covalent bonds when it has no negative charge.

Carbon will form four covalent bonds, nitrogen will form three covalent bonds, oxygen will form two covalent bonds, and hydrogen will form one covalent bond. Click on the related link to see a diagram showing the structure of an amino acid.
Carbon can form four covalent bonds at most, such as in methane.

Sulfur can form two covalent bonds as in H2S, and can form 6 as in SO3. In elemnatl allotropes of sulfur which are covalent bonded, many are cyclic compounds the number of covalent onds is 2.
Carbon form generally covalent bonds; ionic bonds are rare.
