From the octet rule, an element would only be stable if it has a total of eight electrons in its valence shell. Therefore this atom can still acquire 4 more electrons. Since oxygen has 2 available electrons, hence the atom can either form a single bond or double bond with oxygen.

 

Answer:

single and double bonds

An atom with four electrons in its valence shell is capable of forming a covalent bond with single and double bonds with oxygen.

Further Explanation

Chemical bond  

  • A bond is a type of force that is formed between atoms of different through the sharing or transfer of electrons.

Octet rule

  • According to the octet rule for an atom to be stable it must have maximum number of electrons in its outermost energy level. Therefore an atom with four electrons requires four more electrons to attain stability.

Types of chemical bonds.

Covalent bond  

  • This is a type of bond that is formed between non-metal atoms. It is formed as a result of sharing electrons between non-metal atoms involved.
  • When atoms involved contribute equal number of electrons to the bond formation, the type of bond is known as covalent bond. Like in this case, the atom with four outer most electrons may share its electrons with two oxygen atoms to form a compound with a double covalent bond.
  • However, when the shared electrons come from one atom then the bond is known as dative covalent bond.

Ionic bond  

  • This is a type of bond that occurs between metal ions and non-metal ions. Ionic bond occurs as a result of transfer of electrons from one metal atom to another non-metal atom.
  • After the transfer of electrons, metal atom loses electron to form a cation while the non-metal atom gains electrons to form an anion.

Other types of chemical bonds include;

  • Hydrogen bonds
  • Metallic bonds
  • Dipole-dipole interactions, etc.
