Trivia Quiz About Barium - Quiz

Barium is a chemical element which is symbolized with Ba and which is also a member of group 2. It is a soft, silvery alkaline earth metal and because of its high chemical reactivity, it is never found as a free element in nature. The most common naturally occurring minerals of Barium are barite. This short quiz is to put your knowledge of Barium to test to ascertain all that you may know as well as those you don't.


Questions and Answers
  • 1. 

    Which of the following is the atomic number of Barium?

    • A.

      39

    • B.

      48

    • C.

      56

    • D.

      69

    Correct Answer
    C. 56
    Explanation
    Barium has an atomic number of 56. The atomic number represents the number of protons in the nucleus of an atom, and it is unique to each element. In the periodic table, elements are arranged in order of increasing atomic number. Therefore, 56 is the correct answer for the atomic number of Barium.

  • 3. 

    Which of the following is the Pauling scale of Barium? 

    • A.

      0.89

    • B.

      7.12 

    • C.

      1.53

    • D.

      0.95

    Correct Answer
    A. 0.89
    Explanation
    The Pauling scale is a measure of electronegativity, which indicates the ability of an atom to attract electrons towards itself in a chemical bond. Barium, being an alkaline earth metal, has a relatively low electronegativity value. Among the given options, 0.89 is the lowest value and therefore the correct answer for the Pauling scale of Barium.
