Answer:
An impurity is something that ruins the uncontaminated nature of something. If someone accuses you of impurity, they think you or your nature has been spoiled in some way by sin. When water is pure, the only thing in that water is water.
The correct electronic configuration of vanadium 23 is
1s^22s^22p^63s^23p^64s^23d^3
This electronic configuration is correct because it obeys the Aufbau principle which state that electrons fill the atomic orbital of the lowest energy before occupying the higher level. S orbital can occupy a total of 2 electrons, p orbital can occupy a total of 6 electrons while d orbital can occupy a total of 10 electrons. in the electronic configuration above an s orbital is filled before p orbital while the p orbital is filled before the d orbital .
There are eight bonded electrons in this molecule! :)
Families are another names for the columns
