An electron moved from shell n = 2 to shell n = 1. What most likely happened during the transition?
mariarad [96]

Answer: A photon of energy was released.

Explanation: The energy of the orbitals keep on increasing as the size of the orbitals keep on increasing or the value of n keeps on increasing.

The electrons absorb energy when they are irradiated or put at high temperatures and move to higher energy states. The electrons then get back to their ground state by releasing energy in the form of radiations. Thus when an electron move from n = 2 to shell n = 1, the absorbed energy is given off in form of photons of energy.

Energy is released or absorbed in the form of discrete packets of energy called as photons.

A uranium atom has 92 protons in it nucleus use what you know about atoms to predict how many electrons a neutral uranium atom h
sladkih [1.3K]
A neutral atom is one that has no net charge. In other words, the number of positive charges cancels out with the number of negative charges, so the number of protons equals the number of electrons. Uranium has 92 protons, which means it has a total positive charge of +92. To have a neutral charge, the atom MUST have 92 electrons, as that is a negative charge of -92, and the net charge is ultimately (protons + electrons) = ([+92] + [-92]) = 0.
