Where do #"strontium"# and #"calcium"# metal lie in the Periodic Table?


Both metals are alkaline earths; they lie in Group 2 of the Periodic Table. Because the modern Periodic Table reflects electronic structure, each metal has 2 valence electrons. And thus (i) upon oxidation they commonly form #M^(2+)# ions; and (ii) the chemistry of both metals should be to a first approximation similar.

The isotope #""^90Sr# is a radioactive isotope with a short half-life, and this is a dangerous isotope in that it can replace calcium in the human body and cause radioactive poisoning.
