What are the isotopes of each element in the Periodic Table?

Question

We are suppose to list down the isotopes of each element in the Periodic Table and I was wondering if the isotopes are the one like, for example for Hydrogen, 1H, 2H, 3H, 4H, etc...

So is that correct?

Answer 1

yes, Hydrogen has those isotopes. An isotope is an atom of the same element which has different number of neutrons, for example Chlorine, regularly the neutron number is 17, but it has isotopes of 18 neutrons too. :D

Answer 2

Yes, those would be isotopes. Isotopes have different mass numbers because they have different number of neutrons.

Answer 3

yes, you are correct.

the isotopes of an element has same atomic number and different mass.

e.g. Hydrogen have seven  isotopes.

     protium = atomic number = 1, mass number = 1

     deuterium  = atomic number = 1, mass number = 2

  tritium = atomic number = 1 , mass number = 3

  hydrogen-4 = atomic number = 1, mass number = 4

hydrogen-5 = mass number =5

hydrogen 6 = mass number = 6

hydrogen 7 = mass number = 7.

other e.g. is of carbon , it has three isotopes.

carbon -12 = mass number = 12

carbon 13 = mass number = 13

carbon 14 = mass number = 14
