What Do You Know About Terbium?

1. Terbium has an atomic number of?

88

65

92

111

Terbium has an atomic number of 65 because the atomic number represents the number of protons in an atom's nucleus. Each element has a unique atomic number, and in the case of terbium, it has 65 protons. The other options (88, 92, and 111) are incorrect as they do not correspond to the atomic number of terbium.

9. What function does Terbium perform in fuel cells which operate at elevated temperatures?

Drying agent

Catalyst

Crystal stabilizer

Dopant

Terbium performs the function of a crystal stabilizer in fuel cells that operate at elevated temperatures. It helps to maintain the structural integrity of the crystal lattice, preventing it from breaking down or undergoing undesirable changes due to the high temperatures. This stabilization is crucial for the efficient and reliable operation of the fuel cell.

10. How many stable isotopes has terbium?

3

1

4

5

Terbium has only one stable isotope. Isotopes are variants of an element that have the same number of protons but different numbers of neutrons. Stable isotopes do not decay over time, unlike radioactive isotopes. In the case of terbium, it has one stable isotope with 65 protons and 94 neutrons, which is terbium-159.
