Yes they are. Also note that hydrogen 2 is more usually called deuterium. And hydrogen 3 is called tritium.
Hydrogen-1 and hydrogen-2 isotopes are radioactively stable.
Each isotope of hydrogen has 1 proton in the nucleus. The difference between the isotopes lies in the number of neutrons: hydrogen-1 has 0 neutrons, hydrogen-2 (deuterium) has 1 neutron, and hydrogen-3 (tritium) has 2 neutrons.
Both hydrogen-1 and hydrogen-2 are isotopes of hydrogen, with hydrogen-1 being the most common isotope and hydrogen-2 being a rare isotope known as deuterium. Both isotopes consist of one proton in their nucleus, but deuterium also has one neutron alongside the proton, making it heavier than hydrogen-1.
There are three known naturally occurring isotopes of hydrogen; hydrogen-1 with one proton and no neutrons, hydrogen-2 with one proton and one neutron, and hydrogen-3 with one proton and two neutrons.

Hydrogen-1 and hydrogen-2 isotopes are radioactively stable.
Isotopes of hydrogen are Hydrogen-1 (protium), ‎Hydrogen-2 (deuterium), ‎and Hydrogen-3 (tritium).
Isotopes have different number of neutrons, in the given isotopes, there are 0 and 1 neutrons respectively.
Hydrogen has 1 unstable isotope, and 2 stable isotopes.
Isotopes (of hydrogen) differ in the number of neutrons in the nucleus of the atoms.
Hydrogen-1 and hydrogen-2 isotopes are radioactively stable.
Hydrogen-1 isotopes have one proton and no neutrons. Hydrogen-2 isotopes have one proton and one neutron.
Each isotope of hydrogen has 1 proton in the nucleus. The difference between the isotopes lies in the number of neutrons: hydrogen-1 has 0 neutrons, hydrogen-2 (deuterium) has 1 neutron, and hydrogen-3 (tritium) has 2 neutrons.
Hydrogen-1 and hydrogen-2 are examples of isotopes of hydrogen. Hydrogen-1, also known as protium, has no neutrons, while hydrogen-2, or deuterium, contains one neutron. These isotopes have the same atomic number but different mass numbers due to the varying number of neutrons in their nuclei.
Three isotopes: Protium, deuterium and tritium with 0, 1 and 2 neutrons. all isotopes have 1 proton and 1 electron.
Both hydrogen-1 and hydrogen-2 are isotopes of hydrogen, with hydrogen-1 being the most common isotope and hydrogen-2 being a rare isotope known as deuterium. Both isotopes consist of one proton in their nucleus, but deuterium also has one neutron alongside the proton, making it heavier than hydrogen-1.
You seem to be referring to isotopes of hydrogen.
