An element's atoms are exactly the same - no matter where that element is found. A. True
B. False

B. False

Explanation:

All the atoms of an element are not entirely the same no matter where they are found.

The phenomenon of isotopy brings a different perspective to the identity of an element.

Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei. Isotopes of an element have the same electrons but differ in their masses. They also differ in their chemical properties.
