Answer 2

Answer:

isotopes are atoms of same element having different atomic mass but same atomic number.

Explanation:

isotopes isotopes have not been given separate place in the modern periodic table.dinosaur tops are placed with their atoms as all of them have same atomic number

for example -

hydrogen has three isotopes,

hydrogen with atomic mass 1 is called deuterium.

hydrogen with atomic mass 2 is called tritium

hydrogen with atomic mass 3 is called protium.

these isotopes aren't given a separate column in the modern periodic table.

they exist within the hydrogen element modern periodic table.
