When drawing a Lewis structure for a free radical, which type of atom is more likely to receive the unpaired electron?

The less electronegative atom

Explanation:

The less electronegative atom have less electrons surrounding them, hence they are more likely to receive the unpaired electron. On the other hand, the more electronegative atom are more likely to be surrounded by more electrons, making them fulfill their octet.

The unpaired electrons are what cause free radicals to be highly chemically reactive.
