Terbium has an atomic mass of?
- A.
158
- B.
188
- C.
198
- D.
101
Correct Answer
A. 158Explanation
Terbium has an atomic mass of 158. This is the correct answer because atomic mass refers to the average mass of all the isotopes of an element, taking into account their relative abundance. In the case of terbium, the average atomic mass is 158 atomic mass units (amu).Rate this question:

- A.
Cral Roger
- B.
Carl Gustaf
- C.
Ellie Ristik
- D.

Terbium has an atomic number of?
- A.
88
- B.
65
- C.
92
- D.
111
Correct Answer
B. 65Explanation
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.Rate this question:

Terbium is used as a dopant in which of these compounds?
- A.
Calcium fluoride
- B.
Zinc oxide
- C.
Zinc fluoride
- D.
Magnesium oxide
Correct Answer
A. Calcium fluorideExplanation
Terbium is used as a dopant in calcium fluoride. Dopants are added to a material to alter its properties. In the case of calcium fluoride, terbium is added to enhance its luminescent properties. Terbium-doped calcium fluoride is commonly used in scintillation detectors, X-ray imaging, and other applications that require the detection and measurement of radiation.Rate this question:

What function does Terbium perform in fuel cells which operate at elevated temperatures?
- A.
Drying agent
- B.
Catalyst
- C.
Crystal stabilizer
- D.
Dopant
Correct Answer
C. Crystal stabilizerExplanation
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.Rate this question:

Which of these is an ore of terbium?
- A.
Chlorite
- B.
Bastnasite
- C.
Lorite
- D.
Metite
Correct Answer
B. BastnasiteExplanation
Bastnasite is an ore of terbium. Terbium is a rare earth element that is commonly found in minerals such as bastnasite. Bastnasite is a group of rare earth carbonate minerals that contain a variety of rare earth elements, including terbium. Therefore, bastnasite can be considered as an ore of terbium.Rate this question:

Terbium reacts with hot water to form?
- A.
Terbiumite
- B.
Terbium oxide
- C.
Terbium hydroxide
- D.
Terboxide

How many stable isotopes has terbium?
- A.
3
- B.
1
- C.
4
- D.
5
Correct Answer
B. 1Explanation
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.Rate this question:
