The electrons in an atoms orbit around the nucleus. These orbits are arranges in several layers called shells there are theoretically 7 such shells are possible. Starting from the shells closest to the nucleus these are designates as shells K, L, M, N, O, P and Q. The maximum numbers of electrons that each shell can contain is fixed. Further electrons in any shell up to shell O exist only when the maximum possible numbers of electron in all previous shell are present.
In the given question the number of electrons in shell M is given as 5, against the maximum 8 possible electrons n that shell. This means that there are no electrons beyond shell M and the number of electrons in shell K and L is equal to minimum number of electrons in these shells, which is 2 and 8 respectively. Thus actual number of electrons in the given element is equal to 15.
