Periodic Table of Elements with Valence Electrons Trends. In the below periodic table you can see the trend of Valence Electrons. For facts, physical properties, chemical properties, structure and atomic properties of the specific element, click on the element symbol in the below periodic table. Calcium is the fifth most abundant metalic element in the earth's crust, but is never found in the elemental form because it is so reactive. It is found in limestone (CaCO 3) gypsum (CaSO 4. 2H 2 O) and fluorite (CaF 2). Pure calcium is a shiny soft metal that will react violently with water to produce hydrogen. Calcium Page One. Calcium has valence of 2, forming the calcium ion Ca2+. The phosphate ion, PO43- contains five valent phosphorus and divalent oxygen along with three extra electrons. Compounds do not have a.
