Question

which choice ranks the atoms from lowest to highest electronegativity? as < sn < s < f sn < as < s < f s < f < sn < as f < s < as < sn

Explanation:

Electronegativity increases across a period and decreases down a group in the periodic table. Sn is in Group 14 and Period 5, As is in Group 15 and Period 4, S is in Group 16 and Period 3, and F is in Group 17 and Period 2. So Sn has the lowest electronegativity among them and F has the highest.

Answer:

Sn < As < S < F
