oxygen contains 6 electrons in its outermost shell contains ,to complete its octet it shares 2 electrons and hence form two covalent bonds(1 sigma and 1 pi bond).
Technically, there is only one covalent bond, but since it involves four atoms, it is usually called a "double" bond. Therefore, an answer of two might be preferred.
Covalent bonds hold the atoms together in a water molecule. In covalent bonds atoms share electrons.
Covalent bond
Non polar covalent bond.
NO3 is a nitrate ion. Yes, the nitrogen and the oxygen atoms in NO3 are bonded together by covalent bonds.
Oxygen is an element so it does not bond it is pure but if you join two oxygens they are covalent bonded
Water is a covalent compound in which hydrogen and oxygen are bonded together by covalent bonds.

The bond in water is covalent.
Covalent bonds hold the atoms together in a water molecule. In covalent bonds atoms share electrons.
Covalent bond
more than one oxygen atom joined together by single covalent bonds
The polar covalent bond between the hydrogen and oxygen atoms holds it together.
Hydrogen is linked by a covalent bond to an atom of oxygen. The covalent bonds are polar, as the oxygen atoms have a slight negative charge.
Hydrogen is linked by a covalent bond to an atom of oxygen. The covalent bonds are polar, as the oxygen atoms have a slight negative charge.
Non polar covalent bond.
Covalent bonds. The hydrogen and oxygen bond together by sharing outer shell electrons.
