Guida verificata passo dopo passo1
Identify the group number of alkaline earth metals on the periodic table, which is group 2.
Recall that elements in group 2 have two valence electrons in their outermost shell.
Understand that these elements tend to lose their two valence electrons to achieve a stable noble gas electron configuration.
Recognize that losing two electrons results in the formation of ions with a 2+ charge, called 2+ cations.
Conclude that alkaline earth metals most commonly form 2+ cations.
