Consider the two electron arrangements for neutral atoms A and B. The outer electron of atom B has moved to a higher energy state. What could cause this difference? A - 1s22s22p63s1
B - 1s22s22p65s1

Electrons were knocked out of B by high energy particles.
Atom B has lost energy, perhaps by cooling.
Atom B has absorbed energy, perhaps by heating.
