Atomic number is the number of protons. In a neutral atom, the number of protons is equal to the number of electrons. So, in your example, the number of electrons in this atom is 14. The first energy shell can take 2 electrons, the second energy shell can take 8 electrons, and the third energy shell can take 18 electrons. If there are 14 total electrons, 10 would be found in the first two energy shells, leaving 4 for the third energy shell.
In the second energy level, eight electrons are allowed at most.
First energy level can hold 2 electrons.Second energy level can hold 2 + 6 = 8 electrons. Total = 10 electrons.

The maximum number of electrons in the second principle energy level (n=2) is 8. This can be determined from 2(n^2) which for n=2 would be 2 x 4 = 8. It can also be seen by writing the electron configuration for n=2 which would be 2s2 2p6 for a total of 8 electrons.
"energy of elecrons" - I guess you mean of *electrons*. Current is the measure of the number of electrons flowing past a point: one amp of current is about 6.2415093×1018 electrons per second

An atom with seven electrons will have five electrons in the second energy level.
