Question

which element has the greatest electronegativity. nitrogen (n) or arsenic (as)?
arsenic (as)
nitrogen (n)

Explanation:

Step1: Recall periodic table trends

Electronegativity increases across a period and decreases down a group. Nitrogen (N) is in period 2, group 15. Arsenic (As) is in period 4, group 15.

Step2: Compare positions

Since N is above As in the same group (group 15), and electronegativity decreases down a group.

Answer:

Nitrogen (N) has greater electronegativity than Arsenic (As).
