Question

State whether the following statement is True or False. ‘The isotopes of an element differ in the number of protons present in them.’​

Answer 1

Answer:

Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.
