Depends on what you mean by number of electrons. Calcium has 20 electrons and oxygen has 8 electrons for a total of 28 electrons. But if you mean how many VALENCE electrons, then the calcium has 2 and the O has 6 for a total of 8 valence electrons.
There are no valence electrons in calcium ion and eight in oxide ions.
Calcium Oxide is CaO and thus has 1 atom each of calcium and oxygen and thus a total of two atoms.
This depends on the isotopes of calcium and oxygen considered.
calcium has 20 neutrons and electrons
calcium oxide --> calcium + oxygen
Calcium (elemental Ca)= Calcium Oxide x 0.715 so very approx 70% of Calcium Oxide is Calcium in the elemental form.
Calcium oxide (CaO) contain calcium and oxygen.
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
Calcium-41 has 21 neutrons.
20 neutrons
The most stable isotope, calcium-40 has 20 neutrons.
Just two: calcium and oxygen.
calcium oxide is calcium combine whit oxygen
calcium has 20 neutrons and electrons
There are 214 protons and neutrons in the molecule.
CaO is calcium oxide
Calcium oxide is legal.
calcium oxide --> calcium + oxygen
The chemical name for CaO is Calcium Oxide.The common name for calcium oxide is quick lime.
Calcium (elemental Ca)= Calcium Oxide x 0.715 so very approx 70% of Calcium Oxide is Calcium in the elemental form.
