What is the chemical formula for calcium oxide? | Socratic
2014年11月6日 · Since the charges of the calcium and oxide ions are equal but opposite, the calcium and oxide ions form a 1:1 ratio (2+ + 2− = 0), and the chemical formula is CaO. The formula for calcium oxide is CaO. Calcium oxide is an ionic compound composed of the metal calcium and nonmetal oxygen. Calcium is an alkali earth metal (group 2/IIA).
How can I write the formula for calcium oxide? | Socratic
Jun 14, 2014. The formula for calcium oxide is CaO. This compound is ionic which means that a positively charged ion, a cation, has an electrostatic attraction to oxygen, which is negatively charged, an anion. Since calcium has a plus 2 charge and oxygen has a negative 2 charge, there is one ionic bond holding these atoms together in an ionic bond.
What is the ionic formula for calcium oxide? - Socratic
2013年12月19日 · 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 …

Decomposition Reactions - Chemistry - Socratic
2014年1月22日 · The breaking of chemical bonds requires the addition of energy, usually in the form of heat. When a compound is heated, its atoms move about more vigourously. This movement can break chemical bonds. For example, if calcium carbonate is strongly heated, it decomposes into calcium oxide and carbon dioxide. CaCO₃(s) → CaO(s) + CO₂(g)
