Dec 15, 2016· CaO Calcium has a valence of +2 The oxide ion has a charge of 2 (See periodic table for these values) Ca^(2+) O^(2)=CaO. ... What is the formula for calcium oxide? Chemistry The Mole Concept Determining Formula. 1 Answer MeneerNask ... Do I need to know the number of moles of each element to determine the formula of the compound?
May 27, 2018· Here is the required equation CaCO3 CaO + CO2 Since reactant is equal to the product. Hence the chemical equation is fully balanced.
Dec 19, 2013· 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 cation. 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 .
