According to the Bohr model of an atom, what happens when an electron moves from the second energy level to the third energy lev
el and then back to the second energy level? Energy is absorbed and then stored in the atom. Energy is released and then absorbed to form an absorption line. Energy is absorbed and then released to form an emission line. Energy is released from the atom, and the outer level is weakened.
<span>Energy is absorbed and then released to form an emission line.
When electrons absorb energy they increase there energy level. This is only temporary and the excited electron then relaxes back down to its original energy level releasing energy.
The energy is released in form of EM radiation of a specific frequency depending on the element and how many energy levels the electron relaxes. This forms an emission line.</span><span />
When water vapor in the atmosphere loses heat and cools down, condensation happens. As the water vapor cools down and condenses, it attaches to small particles of dust floating in the atmosphere, forming tiny liquid water droplets.
