Question

(a) What are isotopes? Write three isotopes of hydrogen. Why do isotopes show similar chemical properties?

Answer 1

Hey mate

Isotopes are defined as atoms of the same element having same atomic number but different mass numbers.

The 3 isotopes of hydrogen are protium, deuterium and tritium.

Chemical properties depend on their electronic configuration,As isotopes of an element have similar electronic configuration therefore they show similar chemical properties.

Hope it helps you
