Problem: Consider the A2X4 molecule depicted below, where A and X are elements. The A- bond length in this molecule is exttip{d_{ m 1}}{d_1}, and the four A- bond lengths are each exttip{d_{ m 2}}{d_2}.In terms of exttip{d_{ m 1}}{d_1} and/or exttip{d_{ m 2}}{d_2}, how could you define the bonding atomic radius of atom X?

Problem Details

Consider the A2X4 molecule depicted below, where A and X are elements. The A- bond length in this molecule is , and the four A- bond lengths are each .A diagram shows A single bonded to A; each A is also single bonded above and below to X.  The distance between A and A is d1 and the distance between each A and X is d2.

In terms of and/or , how could you define the bonding atomic radius of atom X?
