Answer:
NITROGEN-11:
PROTONS:7
NEUTRONS:11-7=4
ELECTRONS:7
NITROGEN-14
PROTONS:7
NEUTRONS:14-7=7
ELECTRONS:7
NITROGEN-25
PROTONS:7
NEUTRONS:25-7=18
ELECTRONS:7
EXPLANATION
NUMBER OF PROTON = ATOMIC NUMBER IN PERIODIC TABLE
NO. OF ELECTRON= NO.OF PROTONS
NO. OF NEUTRON = MASS NUMBER - PROTON NUMBER
#MASS NUMBER IS GIVEN IN NAME OF ISOTOPE
NITROGEN -11 HAS MASS NUMBER 11
