Question

multiple answer 1 point
1 which of the following form cations? check all that apply.
aluminum
calcium
nitrogen
chlorine

Explanation:

Cations are positively - charged ions. Metals tend to lose electrons to form cations. Calcium (\(Ca\)) and Aluminum (\(Al\)) are metals. Calcium loses 2 electrons to form \(Ca^{2 +}\) and Aluminum loses 3 electrons to form \(Al^{3+}\). Chlorine (\(Cl\)) and Nitrogen (\(N\)) are non - metals. Non - metals tend to gain electrons to form anions. Chlorine gains 1 electron to form \(Cl^{-}\) and Nitrogen can gain 3 electrons to form \(N^{3 -}\).

Answer:

Calcium, Aluminum
