Which statement is true? isotopes are atoms of different elements which have the same mass. isotopes of a given element have equal numbers of neutrons. isotopes of a given element have very similar chemical properties. isotopes of a given element have equal numbers of protons and neutrons. isotopes are atoms that have gained or lost electrons.

The correct statement is isotopes of a given element have very similar chemical properties.

Explanation:

Isotopes are defined as the species which have same atomic number. They are defined as the substances which have same number of protons but have different number of neutrons.

As, these species have same atomic number. So, they have same number of protons and electrons.

And the species which have same number of electrons will show similar chemical properties.

Thus, the correct statement is isotopes of a given element have very similar chemical properties.
