Calcium is in group 2. Therefore it's most probable charge is Ca2+.
A dipositive ion, with formula Ca++.
2 +; Ca2+, cation
the expected charge in calcium is 40.
Plus 2 (+2).

loses 2 electrons to form a calcium ion with 2+ charge

2+
Calcium forms a 2+ ion.
It would be unethical to use this service to answer exam or graded questions. CaCl2 + 2NaOH --> 2NaCl + Ca(OH)2 Calcium Chloride + Sodium Hydroxide --> Sodium Chloride + Calcium Hydroxide Why: Ca ion has 2+ charge Cl ion has 1- charge Na ion has 1+ charge OH polyatomic ion has 1- charge

Well the charge on the compound would be stable (0) when bonded, because the Calcium has given it's electrons to the Oxygen atom. But the charge on the calcium ion itself would be 2+

Sodium ions have a +1 charge, whereas calcium ions have a 2+ charge.

It would form the negatively charged phosphide ion with a charge of 3-, and the symbol P3- .
