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
they all have one valence electron.
Calcium is a non metal element. There are 20 electrons in a single atom.
eight
Oxygen has six valence electrons.
Potassium atom has 1 valence electron
during the formation of calcium iodide,calcium donates two of its +ve ions each to a fluorine atom(2 in number) thereby making its octet and also fulfills the octet formation of each of fluorine atom..
4
Calcium has 2 valence electrons, like all Group 2 elements.
A hydrogen atom has 1 valence electron.
they all have one valence electron.
One calcium atom will form an ionic bond with one sulfur atom, since calcium will donate its two valence electrons to sulfur in order to achieve a stable electron configuration.
2
One. A hydrogen atom contains only one electron, and it is a valence electron.
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.
Calcium is a non metal element. There are 20 electrons in a single atom.
It depends on the atom. List what element the atom is from.
It has 8 valence electrons.
