Which of the following pairs are isotopes of each other? a. 32s and 32p b. 18o and 18f c. 7li and 9be d. 14n and 15n

14N and  15 N  is  the  pairs  that  are  isotope  of  each  other.This  is  because  isotope is  are  different  kind  of  atoms  of  the  same  element  which have  same  number  of  protons(atomic  number)  but  different number neutrons and  different mass  number. 14N and  15N   are  isotope  of  nitrogen  since  has  different  neutron.
