Question

what do we mean by Isotopes?​

Answer 1

Answer:

isotopes aretwo or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei

Answer 2

Answer:

Atoms of the same element having different mass number but same atomic number are called isotopes.

Explanation:

Isotopes

The atoms of an element with same atomic number may have different mass numbers. Thus, we can say that atoms of an element have same number of protons, but some of them may have different number of neutrons. Therefore, atoms of the same element having different mass number but same atomic number are called isotopes.

Properties of Isotopes

1. All the isotopes of an element have same chemical properties as they have same atomic number.
2. Isotopes of an element have same electronic configuration as they have same number of electrons.
3. The isotopes of an element differ in their physical properties as they have different mass numbers. They have different melting point, boiling point, density, etc.
