Answer: Noble gases
Explanation:
Electronegativity is the ability of an atom to gain an electron. Noble gases already have 8 electrons, so they don’t need to gain electrons. If they don’t gain electrons, it has no electronegativity.
In this question, XB3(aq) is an ionic compound which will have the releasing of 3 B⁻ ions ions in water for every molecule of XB3 that dissolves.
XB3(s) --> X+(aq) + 3 B⁻(aq)
[B⁻] = 0.22 mol XB3/1L × 3 mol B⁻ / 1 mol XB3 = 0.66 M
The answer to this question is [B⁻] = 0.66 M
