The number of elements among the following which have lower electronegativity than ' S '
N, Na, P, O, F, B, Se
Answer:
4
Solution:
Electronegativity (Pauling scale approx):
S ≈ 2.58
Compare:
N (3.0) higher
Na (0.9) lower
P (2.19) lower
O (3.44) higher
F (3.98) higher
B (2.04) lower
Se (2.55) slightly lower
Lower than S: Na, P, B, Se → 4 elements
