This is wrong naw the and ought to be option D and not B how can the number of electron equal to that of neutron dats impossible it should be the number of electron equal to the number of proton while the only condition in which dis might not be correct is when have ions ( where we have loss or gain of electron) then the number of electron will be lesser or greater band not equal to the number of proton( atomic number) but I will love myschool to prove their point or correct dis plsssssss š„š„š„

Please sir, for a neutral atom, the number of protons is equals the number of electrons. So the correct option is D.
Thanks.
Note: Proton is positively charged and electron is negatively charged. For instance, when a sodium atom loses an electron, it becomes positively charged because there will be more proton than electron at this time since the atom becomes an ion. Thus, the number of the electron has reduced by one and that account for the excess positive. Therefore, electron and proton are equal for a neutral atom because it's not an ion
