Which of the following is the Pauling scale of Barium?
- A.
0.89
- B.
7.12Â
- C.
1.53
- D.
0.95
Correct Answer
A. 0.89Explanation
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.Rate this question:
