# of
protons
# of
neutrons
# of
electrons

Answer 1

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

Step-by-step 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
