A double bond. Each atom that can share valence electrons has a bonding capacity corresponding to the number of covalent bonds the atom can form. When the bonds form, they give the atom a full complement of electrons in the valence shell. The bonding capacity of oxygen, for example, is 2. ( O=O )
Double
Molecules or covalent compounds are formed by the sharing of valence electrons.
Valence electrons
false
by sharing of valence electrons
False. Sharing valence electrons to make a bond creates a covalent bond, not an ionic bond.

Covalent bonds are formed by sharing electrons of the valence shell.
false
by sharing of valence electrons
False. Sharing valence electrons to make a bond creates a covalent bond, not an ionic bond.
In metallic bonding, the valence electrons freely 'jump' from atom to atom, forming kind of an electron sea.
This is true, but they are not the same as covalent bonds, which are also the sharing of electrons.
