It is a covalent bond. Each hydrogen atom wants to have a full outer shell of 2 electrons. As each atom has only 1 electron in its shell they can share the electrons between them.
The polar covalent bond between the hydrogen and oxygen atoms holds it together.
a hydrogen bond holds two atoms of hydrogen together.
Covalent bond.
The two hydrogen atoms in a hydrogen molecule are held together by a covalent bond.
Mostly hydrogen bonds.
The two atoms share their electrons - so it is a covalent bond ie a shared pair.
polar covalent bond
The chemical bond in water is covalent.
chemical bond holds together the atoms in a substance
The bond between an oxygen and hydrogen atom is polar covalent.
In sodium metal the atoms are held together by metallic bonds.
Covalent bond is formed by the sharing of electrons between two atoms and it is this force of attraction that holds the atoms in covalent bond together.
