what are isotopes ? write 3 isotopes of hydrogen why do isotopes show similer chemical properties?

Answer:
what are isotopes?
Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes.
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
write 3 isotopes of hydrogen why do isotopes show similer chemical properties
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.
Answer:
Isotopes are elements having the same atomic no., but having different atomic masses.
These are elements which have the same no. of protons and electrons, but different no. of neutrons, resulting in different atomic masses.
They have same chemical properties because they essentially are the same element, but with different no. of neutrons. Difference in no. of neutrons doesn't affect the chemical properties of any element.
Eg:- Isotopes of Hydrogen are protium, deutrium and tritium (masses of 1,2,3 respectively).
