Question

Rank from largest to smallest atomic radius. To rank items as equivalent, overlap them. A. Mg B. P C. Cl D. Al E. Ar

Answer 1

Mg > Al > P > Cl > Ar

Step-by-step explanation:

Mg / P / Cl / Al / Ar

The tendency of atomic radia is that the higher the period, the higher the radius; and that the higher the group, the smaller the radius.

• Mg is the furthest left and down between the options, so that's the largest one.

• Just right of Mg there's Al, so that's the next one.

• Going by the tendency, the next ones should be P and Cl.

• Ar is the furthest right, so that's the smallest one.
