No
Metals are found on the left side of the Periodic Table, so they need to lose electrons to be like the noble gases and satisfy the octet rule. When an atom loses electrons, it becomes positive, because electrons are negative.
As for knowing whether an anion is positive or negative, you just have to memorize the fact that cations are positive and anions are negative.
No. Metals generally have lower electronegativity and form cations.
Alkali metals generally form cations by losing their outermost electron to achieve a stable electron configuration.
It is done by Non-metals and metalloids.They form anions
Metals form cations and non-metals form anions.
Generally anions. (e.g. Cl-, F-, O2-, N3-)
No. Metals generally have lower electronegativity and form cations.
Generally non-metals gain electrons and form anions.
Alkali metals generally form cations by losing their outermost electron to achieve a stable electron configuration.
Non metals generally form anions. They gain electrons during ionic bonding.

Metals form cations and non-metals form anions.
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)
