Question

Two molecules with the same atoms arranged in a different order are called isotopes.

True
False

Answer 1

Isotopes are atoms of the same element with different numbers of neutrons. Molecules with the same atoms arranged in a different order are called isomers.

Step-by-step explanation:

Isotopes are not molecules with the same atoms arranged in a different order. Isotopes are actually atoms of the same element that have a different number of neutrons. They have the same atomic number but different mass numbers. On the other hand, molecules with the same atoms arranged in a different order are called isomers.
