First, calcium oxide is an ionic compound and so does not form molecules. In one formula unit (ionic equivalent of a molecule) of calcium oxide there is 1 oxygen (8 protons) atom and 1 calcium atom (20 protons) for a total of 28.

How many electrons are transferred in the ionic bond between Calcium and Oxygen?
Two electrons are transferred between calcium and oxygen to form calcium oxide.
How many protons electrons neutrons are in a molecule of carbon dioxide how many in a molecule of calcium nitrate?
Carbon Dioxide has the formula of CO2, which means 1 Carbon atom and 2 Oxygen atom per CO2 molecule. Carbon12 has 6 protons, 6 neutrons and 6 electrons per atom. Oxygen has 8 protons, 8 neutrons and 8 electrons per atom. One CO2 molecule contains 22 protons, 22 neutrons and 22 electrons. Calcium Nitrate has the formula of Ca(NO3)2. Calcium contains 20 of each. Nitrogen contains 7 of each. Oxygen contains 8 of each. Per molecule there are 1 calcium, 2 Nitrogen and 6 oxygen. Therefore: 20 + (2x7) + (6x8) = 20 + 14 + 48 = 72 protons, 72 Neutrons and 72 electrons. I hope that answers your question.
How many electrons are in an oxygen molecule?
There are 16 electrons in an oxygen molecule as each oxygen atom has 8 electrons.
How many moles of calcium oxide are produced when 36.5 grams of calcium reacts completely with oxygen gas?
2Ca + O2 --> 2CaO The molar mass of Calcium is 40g/mol. 36.5g/40g gives you 0.9125 moles of Calcium. The moles of calcium are equivalent to the moles of Calcium oxide. The answer is 0.9125 moles of calcium oxide. Correct me if I am wrong.
A cation of calcium has a 2 plus charge how many electrons does it have?
calcium has 20 electrons.when it loses 2 electrons, it has 18 electrons.
How many electrons are in a molecule?
Calcium oxide has 20 electrons from the calcium atom, and 8 electrons from the oxygen atom, totaling 28 electrons.
How many electrons are in a CaO molecule?
Calcium oxide has 20 electrons from the calcium atom, and 8 electrons from the oxygen atom, totaling 28 electrons.
How many calcium atoms are there in a molecule of lime?
Calcium oxide (CaO) contain one atom of calcium.
How many neutrons are in calcium oxide?
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.
How many valence electrons does sodium oxide have?
30 electrons per molecule.
How many electrons are transferred in the ionic bond between Calcium and Oxygen?
Two electrons are transferred between calcium and oxygen to form calcium oxide.
How many electrons does Nitrogen Oxide have?
A molecule of nitric oxide has 15 electrons overall, 7 from the nitrogen atom and 8 from oxygen.
How many electrons in Sodium Oxide?
Sodium oxide has the chemical formula of Na2O. To find the number of electrons in this molecule, we first need to know the number of electrons for each of its constituent atoms. The number of electrons in a neutral sodium atom is 11 and the number of electrons in a neutral oxygen atom is 8. So, after doing some simple arithmetic, we find that sodium oxide has 2*11 + 1*8 = 30 electrons per molecule.
How many electrons are gained in the half-reaction O2 electrons - 2O2?
In the half reaction where an oxygen molecule becomes into two oxide ions, it obtains 4 electrons from the oxidising substance.
