The iron is having the number of proton is given, number of proton is 16, number of neutron is 18, whereas number of electrons is 18.
00:20
And we know atomic number, atomic number is equal to number of proton, whereas mass number is number of proton plus number of neutron.
00:45
And for a neutral atom, neutral atom contains equal number of, equal number of electron and proton.
00:59
If there will be increase or decrease in the number of electron indicates it will be any type of iron, whether it will be positive iron or negative iron.

We have given the number of proton, so atomic mass, atomic number, first we will see the atomic number is 16, but the number of electron is given 18, due to this the atom or the iron is having charge minus 2, addition of extra 2 electron, due to addition of 2 electron, whereas its mass number is number of proton 16 plus number of neutron is 18, which is 34...
