List all four of them. ne 4p sibmen isnot following tu SMbmen will ger one erecrron befoveExplanation / Answer
1. The maximum number of electrons in an energy level is given by 2n2, where n= principal energy level
hence the maximum number of electrons in the 14th principal energy level = 2x 142 = 392
2. Number of electrons upto 13th energy level =( 2+6+10+14+18+22+26+30+34+38+42+46+50) = 338
number of electrons in 14th energy level = 54
but since it is half filled it will have =54/2 electrons = 27
hence total number of electrons = 338+27= 365
and we know that in a neutral atom the number of electrons are equal to number of protons
therefore the number of protons are 365
(14th energy level has 27 orbitals and not 7)
3. More information (mass number) is required to determine the number of neutrons. hence data insufficient.
