No, it is not true. When metals loose electrons they become cations.
Cations and anions are in ionic bond. They come from metals and non-metals.
Cations.
Non metals tend to form Anions as they gain electron(s). This occurs normally and usually naturally. There are cases where nonmetals can become Cations as well but it would take a lot of energy to take away an electron from the valence shell. (Refer to Ionization Energy)
Nonmetals usually accept electrons to become negative ions (anions), e.g. Cl + e- --> Cl-.
It is done by Non-metals and metalloids.They form anions
Non metals tend to be at the Right Hand Side of the periodic table. They therefore tend to need to GAIN electrons to get a stable octet-noble gas configuration. Gaining electrons mean they become anions. The reverse is true for metals.
Anions are negatively charged atoms.Non metals gain electrons to form anions. They are placed on right side in the periodic table.
No. Like other metals potassium forms a monatomic cation.
No. Metals generally have lower electronegativity and form cations.
Non metals are likely to steal electron. They form anions.
Metals form cations and non-metals form anions.
