How many main isotopes of hydrogen are there?
Q: How many main isotopes of hydrogen are there?
A: There are three main isotopes of hydrogen: protium, deuterium, and tritium.
Q: Are protium and deuterium stable isotopes?
A: Yes, protium and deuterium are stable isotopes.
Q: What is the half-life of tritium?
A: Tritium is radioactive and has a half-life of about 12 years.
Q: How many other hydrogen isotopes have scientists created?
A: Scientists have created four other hydrogen isotopes: 4H to 7H.
Q: Do these four additional hydrogen isotopes exist naturally?
A: No, these isotopes are very unstable and do not exist naturally.
Q: What makes the main isotopes of hydrogen unique?
A: The main isotopes of hydrogen are unique because they are the only isotopes that have a name.
Q: Do deuterium and tritium have their own symbols?
A: Yes, deuterium and tritium sometimes get their own symbols: D and T. However, the International Union of Pure and Applied Chemistry does not like these names very much, even though they are often used.
