What is the electric charge on the ion in the compound calcium oxide?
Well the charge on the compound would be stable (0) when bonded, because the Calcium has given it's electrons to the Oxygen atom. But the charge on the calcium ion itself would be 2+
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.
What is the electric charge on the calcium ion in the compound calcium oxide?
Well the charge on the compound would be stable (0) when bonded, because the Calcium has given it's electrons to the Oxygen atom. But the charge on the calcium ion itself would be 2+
Will electrons be gained or lost if the atom of oxygen becomes stable?
the atomic no of oxygen is 8 to reach the nearest noble gas electronic configuration it excepts 2 electrons and becomes isoelectronic to Neon.
What kind of chemical reaction is the burning of magnesium in oxygen?
it is the oxidation of Magnesium into Magnesium oxide which appears as a white powder.That is classified as a redox reaction, a term which is a contraction of reduction-oxidation. The magnesium is oxidized and the oxygen is reduced. The terms refer to the transfer of electrons. Electrons have a negative charge, so a recipient of electrons, such as oxygen is reduced in the sense that its charge becomes negative.
When an oxygen atom becomes an oxide ion it has a charge of -2 why?
It has gained 2 electrons.
What is the electric charge on the ion in the compound calcium oxide?
Well the charge on the compound would be stable (0) when bonded, because the Calcium has given it's electrons to the Oxygen atom. But the charge on the calcium ion itself would be 2+
Who has more electrons nitrogen calcium oxygen or sodium?
Calcium has the most electrons. Nitrogen has 7, calcium has 20, oxygen has 16 and sodium has 11 electrons.
What elements combine to form the compound represented by the formula CaO?
the cation (metal) calcium (charge 2+) gives its valence electrons to the anion (nonmetal) oxygen (charge 2-) to create an ionic bond between the elements calcium and oxygen, named calcium oxide (:
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 are the elements oxygen and calcium different on the periodic table?
Calcium can loose 2 electrons. Oxygen can gain 2 electrons.
How many electrons does calcium sulfate have?
The calcium ion has 18 electrons. The sulfate ion has 16 electrons from sulfur, 32 electrons from oxygen atoms and two from the charge. Altogether, a (molecule) of calcium sulfate has 68 electrons. * Calcium sulfate is not existing as molecules, 'formula unit' is a better phrase.
What is the cation of calcium oxide?
Calcium and Oxygen are the atoms in Calcium Oxide.
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 electrons would an atom of Oxygen need to have no charge?
Oxygen needs 8 electrons to have no charge.
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.
What is the electric charge on the calcium ion in the compound calcium oxide?
Well the charge on the compound would be stable (0) when bonded, because the Calcium has given it's electrons to the Oxygen atom. But the charge on the calcium ion itself would be 2+
