Depends on what element you are talking about.
Five electrons in the outermost shell of Bismuth (group 15, same as 'parental' Nitrogen)
The valence shell is the outter most shell that contains the most electrons. To find out how many valences there are you would mulitply the electrons. C3H8= (6)3 + (1)8=26 the outer valence shell will be 20.
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
An atom is supposed to have an equal number of electrons and protons, leading to a neutral charge. The number of electrons surrounding an atom is determined by its atomic number, which also dictates its place on the periodic table.
Eight, except for helium which has two.
Seven, as does any other halogen element.

There are 12 electrons in the electron shell of magnesium, the same number as protons. As for the outermost shell, it would be 3s2, meaning there are two electrons in the third "s" shell.

How am i supposed 2 no? im the 1 who asked the question!
Eight, except for helium which has two.
Electrons only fill the first layer of hydrogen, giving it only two. The rest of the layers are all 8.
2 on the inner most, and 8 on every other layer
