Calcium is a non metal element. There are 20 electrons in a single atom.
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.
Calcium loses 2 valence electron to become ionized.
The first layer has two, since the maximum amount of electrons you may have in layer one are two, after the first layer you may have a maximum of eight electrons per layer, so layer one has two, layer two has eight, and layer 3 has a maximum of 18. To find the maximum number of electrons each layer can have do the equation 2(n2) n=number of layers
It loses 2 electrons to obtain the argon configuration of 8 valence electrons.
Calcium has two valence electrons.
Calcium is a non metal element. There are 20 electrons in a single atom.
Calcium has 2 valence electrons, like all Group 2 elements.
Calcium has two valence electrons.
Calcium carbonate has 16 valence electrons. Calcium contributes 2 valence electrons, while each oxygen atom contributes 6 valence electrons.

There are 2 electrons in valence shell of calcium. :-)
Calcium has 2 valence electrons. It is in group 2 of the periodic table, which means it has 2 electrons in its outermost energy level.
Calcium loses 2 valence electron to become ionized.
Silicon has 4 Calcium has 2 Chlorine has 7 Sodium has 1
Two.
Boron has 3 valence electrons, gold has 1 valence electron, krypton has 8 valence electrons, and calcium has 2 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom.
