Electrons wavelengths and frequency

[JustinHorriat_4f]

so is an electron is its own energy source? does that mean it has wavelengths and frequency? and I Just don't get how if its excited it drops down energy levels? I thought if its excited it is given off

I am pretty sure everything in the universe has its own energy. An electron can absorb energy from photons, which causes it to jump up electron levels. When the electron loses that energy, it drops down energy levels, releasing the energy it absorbed originally from the photon. It has its own wavelength and frequency, which is related to the de Broglie equation.

Yes, electrons have its own wavelength and frequency, just as everything, its wavelength is determined by De Broglie equation. But don't mess it up with energy level. After absorbing energy of a photon, the electron jumps to a higher energy level.
