The answer is: The addition of a small dense nucleus at the center of the atom.
The center of an atom is called the nucleus.
Hope I helped!

The work-energy theorem explains the idea that the net work - the total work done by all the forces combined - done on an object is equal to the change in the kinetic energy of the object. After the net force is removed (no more work is being done) the object's total energy is altered as a result of the work that was done.
This idea is expressed in the following equation:
is the total work done
is the change in kinetic energy
is the final kinetic energy
is the initial kinetic energy

Excitation to a higher energy state requires energy which is absorbed from the electromagnetic waves applied.
