Your answer: — · Correct: B

Explanation

Statement 1 is correct: Isotopes are atoms of the same chemical element that have the same atomic number (number of protons) but different mass numbers. This difference in mass number arises because the atoms contain different numbers of neutrons in their nuclei.

Statement 2 is incorrect: Protium (1H), Deuterium (2H), and Tritium (3H) are the three naturally occurring isotopes of Hydrogen, which has an atomic number of 1. Carbon isotopes include Carbon-12, Carbon-13, and Carbon-14, all of which share the atomic number 6 but differ in neutron count.
