Three electron shells.
Answer3 energy levels17 protons and electrons
A neutral atom of xenon has 6 energy levels, with 54 electrons occupying those levels. Xenon has 54 electrons in total, so no electrons would be left over in a neutral xenon atom.
There are 26 electrons in an iron atom. Each neutral iron atom has a total of 26 electrons occupying various energy levels or electron shells.
In an atom, electrons can occupy different energy levels, or orbits, around the nucleus. Electrons in the lowest energy level are closest to the nucleus and have the lowest energy, while electrons in higher energy levels are farther from the nucleus and have higher energy. Electrons can move between energy levels by absorbing or emitting energy in the form of photons.
A selenium atom has 36 inner shell electrons. This includes electrons in the first (2 electrons) and second (8 electrons) energy levels, as well as 18 electrons in the third energy level.

Electrons in the plutonium atom are placed in 7 energy levels.

A neutral atom of platinum has 78 electrons, at 78 energy levels in one cloud.
Maximum of 2n2 where n is the energy level
The period tells you how many energy levels an atom has.
Carbon has 2 energy levels. There are 6 electrons, 6 protons, and 6 neutrons.
An atom of oxygen has 2 energy levels that are occupied - the first energy level (K shell) can hold up to 2 electrons, and the second energy level (L shell) can hold up to 6 electrons. Oxygen has a total of 8 electrons.
None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.
