Explanation:
Calcium has a charge of Ca+2 . Phosphorous has a charge of P−3 . To bond these two ions together, their charges must be equal and opposite. Therefore we need 3 Ca+2 ions to balance with 2 P−3 in order to balance their charges at 6 for the molecule Ca3P2 .
Ответ:
The charge will tell you if the atom is neutral, positive, or negative. "The charge of an atom is the number of protons minus the number of electrons."
