Consider a hydrogen atom in the ground state, what is the energy of its electron?

Now consider an excited-state hydrogen atom, what is the energy of the electron in the n=4 level?

by

The equation for energy is given by: At its ground state [math]n=1[/math] At [math]n=4[/math] This is the best answer for considering a hydrogen atom in the ground state. what is the energy of its electron?

Energy of an electron in a hydrogen atom is:

E= (-2.179 x 10 ^-18 J)(1/n^2)

where n is the principle energy level of the electron.

E= (-2.179 x 10 ^-18 J)(1/4)

E= -2.179 x 10 ^-18 J

E = -5.4 x 10 ^-19 J
