Question

what are isotopes and isobars

Answer 1

#Isotopes are defined as atoms having the same atomic number, but different mass numbers.These atoms contain an equal number of protons and electrons, but a different number of neutrons.

#Isobars are atoms of different elements having the same mass number.These elements have an equal number of nucleons, but different number of protons, neutrons, and electrons.

Answer 2

reference to the ans
here A is mass number and Z is atomic number


the atoms of the same elements having Same Atomic number but different mass number are called isotopes
like hydrogen it has 3 isotopes
it varies due to change in neutron number
protium=Z=1,A=1
deuterium =Z=1,A=2
tritium =Z=1,A=3

isobars are atoms of differnt elements having same mass number but differnt atomic number
like argon =Z=18,A=40 and Calcium=Z=20,A=40
