A calcium atom loses both valence electrons. The particle left behind carries a positive charge and is called a:
AAnion
BCation
CNeutron
DIsotope
Answer & Solution
Correct answer: B. Cation
1. Electrons are negative, so losing two leaves two positive charges unbalanced.
2. A particle with net positive charge is named for moving toward the cathode.
3. It is a cation, here Ca with a 2+ charge.
