Beryllium generally forms covalent bonds. Beryllium is in the 2nd group and 2nd period so it is a very small cation. Smaller cation favors formation of covalent bonds.

In a boron atom, typically three covalent bonds are formed due to its electron configuration (1s² 2s² 2p¹). Boron has an incomplete outer electron shell with only three electrons, so it can share electrons with three other atoms to complete its octet.
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.
A boron atom would need 3 hydrogen atoms to form covalent bonds with it in order to achieve stability. This would allow boron to have a full octet of electrons in its outer shell, satisfying the octet rule.
Sulfur, with an atomic number of 16, can form a maximum of 2 covalent bonds. This is because sulfur has 6 valence electrons and can share these electrons with other atoms to complete its octet, leading to the formation of 2 covalent bonds.
An atom of nitrogen typically forms 3 covalent bonds to achieve a stable electron configuration. However, with a positive net charge, it can form fewer bonds. With a net charge of +1, nitrogen could potentially form 2 covalent bonds, as it would have one less electron to share.
Boron is in group 3 and forms generally 3 covalent bonds. Because forming 3 bonds only gives boron a share of 6 electrons boron compounds are Lewis acids.
In a boron atom, typically three covalent bonds are formed due to its electron configuration (1s² 2s² 2p¹). Boron has an incomplete outer electron shell with only three electrons, so it can share electrons with three other atoms to complete its octet.
Boron has three valence electrons around it. This means it can form three covalent bonds with other atoms by sharing these electrons.
Boron typically forms 3 covalent bonds, while aluminum typically forms 3 covalent bonds as well. Both elements have one less valence electron than a full octet, so they tend to share electrons with other atoms to complete their outer shells.
Boron typically forms three covalent bonds in its compounds. This is because boron has three valence electrons, making it capable of forming three bonds to achieve a full octet in its outer electron shell.
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.
