I believe it is 2, seeing it is a metal, and has 2 valence electrons. Correct me if I'm wrong, I don't have my Periodic Table with me (Calcium -> Ca?).

How many electrons are the third energy level of a calcium atom?
There are 8 electrons in the third energy level of a calcium atom.
How many electrons does calcium lose?
Usually calcium loses 2 electrons, that's why calcium is found in Group 2 of the periodic table.
How many electrons are in the fourth level of a calcium atom?
The electronic configuration of calcium is 2, 8, 8, 2 and the fourth energy level has 2 electrons.
How many electrons does one atom of calcium donate to one atom of oxygen during the formation of the compound CaO?
2
How many electrons does calcium have in the second energy level?
Calcium atoms have 8 electrons in the second energy level. However, they are not the valence electrons. The outermost electrons in a calcium atom in the ground state are 2 4s electrons. So calcium atoms in the ground state have 2 valence electrons in the fourth energy level.
How many electrons does the calcium ion lose from an atom?
It loses 2 electrons.
How many electrons will a calcium atom Ca lose in order to get a noble gas configuration?
Calcium will lose two electrons to gain the noble gas configuration of Argon.
How many electrons in calcium?
There are 20 electrons in a calcium atom.
How many electrons are calcium?
Calcium has 20 electrons in the neutral atom.
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 s electrons are there in calcium?
The neutral atom of calcium has 20 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 atoms does calcium lose?
I am not sure what you mean by atoms, i think you mean electrons (part of an atom).Calcium is in Group 2 of the periodic table so this means that in order to become stable it will lose 2 electrons.
How many electrons do calcium has?
Calcium, as an element, has 20 electrons. But when becomes an ion, it loses two electrons, becoming Ca+2. Therefore, as an ion, calcium has only 18 electrons.18
How many electrons do the calcium?
Calcium is a metal element. There are 20 electrons in a single atom.
How many electrons are the third energy level of a calcium atom?
There are 8 electrons in the third energy level of a calcium atom.
How many Electrons in atom of calcium?
20 electronsIt has 20 protons and 20 neutrons.20 electrons
