Hydrogen naturally exists in the form of three isotopes: Protium (1H), Deuterium (2H or D), and Tritium (3H or T). While Tritium is radioactive and rare, all three are identified as the isotopes of the hydrogen element found in nature.

Think of isotopes as 'versions' of a product that share the same core features (protons) but have slightly different 'add-ons' (neutrons) in their engine room (nucleus).
P-D-T (Protium, Deuterium, Tritium) - 'Please Drink Tea'.
Z=1 тАФ Atomic number (protons) for all isotopes
A=Z+N тАФ Mass number (A) calculation where N is the number of neutrons
Isotopes are atoms of the same element having the same number of protons (atomic number Z=1) but different numbers of neutrons. Protium has 0 neutrons, Deuterium has 1, and Tritium has 2. These variants occur due to the varying neutron count in the nucleus while maintaining the same electronic configuration.
Protium (1H) is the most abundant, making up >99.9% of natural hydrogen.
Deuterium (2H) is also known as 'heavy hydrogen'.
Tritium (3H) is radioactive with a half-life of ~12.3 years.
Deuterium is used in nuclear reactors as a moderator (heavy water).
Tritium is used as a radioactive tracer and in fusion research.
Used in nuclear fusion research
Tracer studies in medicine and chemistry
Tritium is produced naturally in the atmosphere by cosmic rays.
Option '3' is the standard scientific answer for naturally occurring isotopes of hydrogen.
D is correct тАФ There are 3 isotopes of hydrogen existing in nature: Protium, Deuterium, and Tritium.
Always remember that while hydrogen is the simplest element, it is the only one whose isotopes have specific, widely used names (Protium, Deuterium, Tritium).
