Explain, in terms of electron configuration why atoms of the radioisotope produced by the sixth decay in the u-238 disintegration series do not readily react to form compounds?

The reason they don't react is because Elements with full octets are stable, the Elements with no unpaired electrons do not react at all in the decay.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
