Tom-the-Atom, Book 8: A cup of Calcium a day, keeps your teeth and bones from breaking away!Tom-the-Atom introduces representatives of the Alkaline Earth family, Column 2 in the Periodic Table: Calcium (Ca) and Magnesium (Mg). Atoms from Group 2A have only two valence electrons in their outermost shell. They prefer to lose them and keep their inner shell full, to be stable, rather than hunting for six additional valence electrons and filling their outermost shell with eight valence electrons. When they lose those two electrons, the atoms became charged twice positively (because they lost two negative electrons. They are then called divalent positive ions (divalent Cations).
