metals form positive ion because they always lose electrons and after losing electron they have excess of positive charge and have deficiency of electrons.another reason is that metals have more than 3 valence electrons and have low ionization energy
It is possible to make positive ions of nonmetals e.g. oxygen, chlorine, by putting enough energy into them. They normally form negative ions when in a spontaneous reaction.
No, metals do not form negative ions: Only non-metals form negative ions - this ability (to gain electrons) is intrinsic to the nature of non-metals. Only metals form positive ions - this ability (to lose electrons) is intrinsic to the nature of metals. A positive ion (cation) is formed by removing electron(s) from an atom or group of atoms. A negative ion (anion) is formed by gaining electron(s) an atom or group of atoms.
Metals typically form positive ions. The alkali metals and alkali earth metals form positive ions in ionic obnding whilst the transition metals form cations in a lattice of delocalised electrons.
If an atom is electropositive (metals, in general), then they will lose electrons and form positive ions. If an atom is electronegative (non-metals, in general), then they will gain electrons and form negative ions.
Non-metal ions typically form negative ions (ie: Cl-) Therefore they now have an extra electron which is protected from the positive pull of the nucleus by the other electrons and therefore the electron shell has now expanded, making nonmetal ions larger than nonmetal atoms
Metals are usually positive and non-metals are usually negative.

Metals form positive ions and form ionic compounds with negative ions.
Metals tend to form positive ions also known as cations.

Non-metal atoms gain an electron, or electrons, from another atom to become negatively charged ions.

Non Metals
Non-metal ions typically form negative ions (ie: Cl-) Therefore they now have an extra electron which is protected from the positive pull of the nucleus by the other electrons and therefore the electron shell has now expanded, making nonmetal ions larger than nonmetal atoms
The type of ions that metals form are called positively charged ions. The scientific name for positively charged ions is cations.
Because halogens form negative ions, alkali metals form positive ions; both are reactive elements and an electrostatic attraction exist.
