All of those form Ions !
The elements which do not form ions are the elements in group 0 and IV
groups (I, II, III) form positive ions (cations) and the groups (V, VI, VII) form negative ions (anions). Group 0 elements do not form ions at all because they all have a stable number of electrons in the outer shell. There is no loss or gain of electrons, a factor that makes these elements non-reactive.
The Group IV elements tend not to form ions, although metallic elements further down the periodic table can form positive ions. They form Covalent bonds

Hydrogen because its 1s orbital can hold only 2 electrons.
