Question

define isotope with example write one uses of isotope ​

Answer 1

Answer:

isotope are the atoms with same atomic no. but different atomic mass for example isotopes of hydrogen

Answer 2

Answer:

Isotopes are atoms with the same number of protons but that have a different number of neutrons.

Explanation:

The three are all isotopes of hydrogen. As you can see, they have the same atomic number, or number of protons, (number at the lower left of the element) but different atomic masses (number at the upper left of the element).

The number of neutrons can be calculated by calculating the difference between the atomic mass and atomic number. We can see that for the isotopes of hydrogen, they have varying number of neutrons. For protium, the number of neutrons is zero; for deuterium, the number of neutrons is one; and for tritium, the number of neutrons is two.
