According to the Bohr model of the atom, the single electron of a hydrogen atom circles the nucleus

• in specific, allowed orbits.

• in s,p,d,f orbitals

• at any of an infinite number of distances, depending on its energy.

• counterclockwise.

When an electron moves from a higher energy level to a lower energy level....

• energy is absorbed

• energy is released

• an element slits into two elements

• nothing happens
