Calcium - Simple English Wikipedia, the free encyclopedia
Calcium is a chemical element. Its syol on the periodic table (a list of all the elements) is Ca. Its atomic nuer is 20. (The atomic nuer says where Calcium sits in the periodic table.) It has 20 protons and 20 electrons (if is an atom, see ion). The most common isotopes are Ca-40 and Ca-44. Its mass nuer is about 40.08. Calcium is

What is the ionic formula for calcium oxide? | Socratic
2013/12/19· The ionic formula for calcium oxide is simply CaO. Why is this the case? The Calcium ion is an Alkaline earth metal and wants to give up the 2 s orbital elections and become a +2 ion. Oxygen has six valence electrons and is looking to gain two electrons to complete the octet (8) electron count in the valence shell making it a -2 anion. When the charges of the Calcium +2 and the Oxygen -2
