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
Calcium has 2 valence electrons, like all Group 2 elements.
Calcium has two valence electrons.
Calcium has the valence 2+.
eight
Calcium is a non metal element. There are 20 electrons in a single atom.
Potassium atom has 1 valence electron
Oxygen has six valence electrons.
they all have one valence electron.
There are only 2 valence electron found in calcium.
Calcium has 2 valence electrons, like all Group 2 elements.
2
It depends on the atom. List what element the atom is from.
4
It has 8 valence electrons.
5
eight
One. A hydrogen atom contains only one electron, and it is a valence electron.
The number of valence electrons depends on the atom and can vary from 1 to 8.
Calcium is a non metal element. There are 20 electrons in a single atom.
The formula for calcium iodide is CaI2. This means that the calcium atom has transferred one electron to each of two iodine atoms, for a total of two electrons transferred.
