Question

from their positions in the periodic table, arrange the atoms in each of the following series in order of increasing electronegativity.

Explanation:

Step1: Recall the trend of electronegativity in the periodic table

Electronegativity increases across a period from left to right and decreases down a group.

Step2: Analyze the positions of the given elements

• As (Arsenic) and Sb (Antimony) are in Group 15. Since electronegativity decreases down a group, \(As < Sb\).
• C (Carbon) and N (Nitrogen) are in Group 14 and 15 of the second period. As electronegativity increases across a period, \(C < N\).
• H (Hydrogen) has an electronegativity value of 2.2. C has an electronegativity of 2.55, so \(H < C\).

Combining these, we get the order \(As < H < C < N < Sb\).

Answer:

\(As < H < C < N < Sb\)
