Depends upon the atom and element, some have an energy level of 0 and it can be +/- for others depending on the number of protons or electrons in said atom.

in the third shell, an electron has more energy and is further from the nucleus

A energy pryramid shows that each feeding level has less energy than the one below it.
no , it only emits energy if it moves from a higher energy level to a lower energy level.
The energy state of an atom is an energy level.
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
There are 8 electrons in the third energy level of a calcium atom.
A boron atom has three electrons in its second energy level.
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
A neutral atom of magnesiumhas two electronsin its outermost energy level
The third energy level of an atom can hold eight electrons.
Electrons
When an atom releases energy in the form of visible wavelengths of light, it indicates that an electron in that atom has gone from an excited energy level, back down to a lower energy level.
Light is generated when photons are emitted from an atom. This occurs when an electron on one energy level of an atom falls to a lower energy level.
The outermost energy level of an atom typically has between 1 and 8 electrons.
