The Nth "shell" of an atom can hold 2N2 electrons. So 2 in the first, 8 in the second, 18 in the third, and so on.
(Both "layer" and "shell" are a bit misleading, though "shell" at least is probably too historically ingrained to eliminate.)

How many electrons are in the third energy level for each element?
I assume you mean for each atom. If I remember correctly, the shells go 2, 8, then 18 on the third layer.
How many valence electrons does each atom of nitrogen have?
Nitrogen has five valence electrons.
How many electrons are there in an atom?
It is different for each element. In hydrogen, there is one.
How many electrons are there in each orbit of a neon atom?
2, 8
How many electrons does each neutral chromium atom have?
24 electrons, remember the atomic number of an element tells you how many protons it has. The number of protons = the number of electrons (if the atom isnt charged)
How many protons and electrons does Kr atom have?
A Krypton atom has 36 protons and 36 electrons each.
How many electrons that each atom have?
each of atoms have electrons that equql to atomic number of that of atoms
How many electrons are in the third energy level for each element?
I assume you mean for each atom. If I remember correctly, the shells go 2, 8, then 18 on the third layer.
How many electrons do each what kinds of matter have in each atom?
the cat
How many valence electrons does each atom of nitrogen have?
Nitrogen has five valence electrons.
How many electrons are in the element selenuim?
Atomic number= No. of electrons in the atom. Atomic no. of selenium=34. Therefore,selenium has 34 electrons in each of its atom.
How many protonsneutronand electrons are in an atom of calcium?
20 of each
How many protons and electrons does osmium atom have?
76 of each.
How many electrons does each atom owns in CS2?
about 7
How many electrons will there be in each atom of lithium?
3 total
How many electrons are in an oxygen molecule?
There are 16 electrons in an oxygen molecule as each oxygen atom has 8 electrons.
How many valence electron calcium atom has?
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
