Quantum numbers specify the properties of atomic orbitals and the properties of electrons in orbitals. The first three quantum numbers result from solutions to the Schrodinger equation. They indicate the main energy levels, the shape, and the orientation of an orbital.

The main energy levels are also known as the electron shells of an atom. An electron is permitted to be around an atom.
The principal quantum number, n, designates the main energy levels occupied by electrons. The number of orbitals in an energy level is n2 (n squared), so that the first energy level, n = 1, contains 1 orbital; the second energy level, n = 2, contains 4 orbitals; the third energy level, n= 3, has 9 orbitals; and the fourth energy level, n=4, has 16 orbitals, and so on.
It is all because of a man named Charles Barkla. He was measuring the energy levels of X-rays, and noticed that they came in two main categories, one of which had a higher energy level than the other. He first called them A and B, then realized that there might be levels higher than the one he had called "A". Wanting to leave some room, he decided that K would be a good starting point, and if he later discovered an even higher energy levels he could call them J, I, H and so on down. It turns out there aren't... the K-series was the highest possible energy level for a given atom. But the name had stuck by that point.
The main source of energy is from the sun.
Each main energy level (1 to 7) has at least an s-orbital, p-orbitals are possible from the second level onwards (2 to 7) d-orbitals from 4th level f-orbitals from 6th level

There are located outside the nucleus , revolving it in different energy levels , no positions are 100% sureNeutrons and Protons make up the main mass of an atom, electrons orbit this main mass.They ae around the nucleus. They are in energy levels

The area in which electrons are arranged in energy levels is called "Main Energy Levels." The chart also includes configurations of the electrons. I have attached a link to explain.
the first one because it is closer to the nucleus. :)

Citalopram is primarily used to treat depression and anxiety, so its main effect is on mood rather than energy levels. It can sometimes improve energy levels indirectly by alleviating feelings of fatigue that are associated with depression. However, if you are experiencing significant fatigue or low energy, it's best to discuss this with your doctor to explore appropriate treatment options.

A stairway is a good model for the energy levels in an atom because there is a 'main floor' ( the nucleus ) and steps ( the energy levels ). The nucleus is the start of the stairway of the energy levels, and the other energy levels go off of the nucleus. The first energy level can hold 2 electrons, the second energy level can hold 8. The third energy level can hold 18, and the fourth energy level can hold 32 electrons. In order for an element to be as stable as a noble gas, the outermost energy level has to be full, so sometimes an atom will gain or lose electrons to fill it's outer energy level. Other times it might share electrons with other atoms, so that they don't have to gain or lose a lot of electrons. An example of this would be H2O ( water ). There is one oxygen atom with two hydrogen atoms connected to it, and sharing their electrons with each other.

Coenzyme Q10 is an antioxidant. You produce it naturally in your body. It's main function is to provide energy to your cells. As you age you produce less of it. That's why you tend to have lower energy levels as you get older. http://www.wealthy-choices.com
