Electrons in the outermost energy level are called valence electrons. The number of valence electrons on an atom largely determine its behavior and characteristics.
Valence electrons.
Yes, electrons in an atom exist in specific energy levels known as electron shells. These energy levels are quantized and discrete, with electrons occupying the lowest available energy level first before moving to higher ones.
Covalent [the sharing of a pair of electrons] bond energy.
No. The outermost layer of the Earth is called the crust.
We call that ionizing radiation.

The aufbau principle (text books may also call it the Madelung ordering or the Klechkowski rule) predicts the order in which orbitals are filled. The 4s orbital is filled before the 3d orbitals. Wikipedia has an article see link

Simple answer: Valence electrons losing energy. Expanded answer: Atoms, the most basic unit of matter, contain charged particles call electrons and protons, along with neutral particles called neutrons. Protons and neutrons are found in the nucleus of an atom. Electrons are arranged in specific areas called shells (or orbits). When the electrons are excited (for example, by heat), they jump from one shell to another. Once they fall back they start to emit photons--light. Each element has a different color based on how many valence electrons it has.
We call that ionizing radiation.
Niels Bohr referred to each possible orbit of an electron around the nucleus as a "stationary state." In these stationary states, electrons can occupy specific energy levels without radiating energy. The energy levels are quantized, meaning electrons can only exist in these distinct orbits and not in between them. Each stationary state corresponds to a specific energy level, allowing for the characteristic spectral lines of atoms.
The laser that is shot out of a blaster is powered by a gaseous substance. It worked by introducing the energy to a medium. Most of the gas that was used was Tibanna Gas. When an atom of the medium was exited by the energy source the electrons that were available would transfer or "jump" to another, higher energy level. When they calmed down and returned to their original energy level a photon was released. The photon is what we would call the "laser beam". And there you have it.
When you move an electron in an atom from a lower energy level to a higher energy level, it is called an electron excitation. This process requires the electron to absorb energy to move to a higher energy state.
