Explanation:

The atomic radius (r) of an atom can be defined as one half the distance (d) between two nucli in a diatomic molecule. Atomic radii have been measured for elements. The units for atomic radii are picometers, equal to 10−12 meters.

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.
