Question

Which of the following lose electrons to form cations ?
a. metals
b. non-metals
c. both a and b
d. none of these​

Answer 1

Answer:

a. metals

is the correct answer.

Explanation:

Metals form positive ions (cations). A magnesium atom must lose two electrons to have the same number electrons as an atom of the previous noble gas, neon. Thus, a magnesium atom will form a cation with two fewer electrons than protons and a charge of 2+.

Answer 2

Metals form positive ions (cations). A magnesium atom must lose two electrons to have the same number electrons as an atom of the previous noble gas, neon. Thus, a magnesium atom will form a cation with two fewer electrons than protons and a charge of 2+
