Answer:
Absorption Spectrum
Explanation:
The hot, dense source emits high energy photons of all wavelengths. Some of these photons are absorbed by electrons of cloud to excite them to a higher energy level which appear as dark lines in the spectra and we get Absorption Spectrum.
Kinetic energy. I hope that helps
In the atom, the nucleus is charged positive and the electron is charged
negative. So we know that they're attracted to each other. It takes energy
to keep the electron from falling into the nucleus.
-- If you want to drag the electron farther out from the nucleus, you have to
do work on it ... put energy in to it.
-- When the electron loses energy, it falls in closer to the nucleus. The more
energy it loses, the closer to the nucleus it falls.
-- From the list of choices in the question, the <span>electron moving <em>two energy levels </em>
<em>closer to the nucleus</em> loses more energy than any other choice.
