Can anybody explain?
OpenStudy (abb0t):
calcium carries a \(2^+\) charge
OpenStudy (anonymous):
Calcium is in group 2 of the periodic table, meaning that it has 2 electrons in its (outer) valence shell. So it has to lose those 2 electrons from that to acquire Argon's noble gas structure Ar(2,8,8) . Is this correct?
