Energy level | Definition, Diagram, & Facts | Britannica
WEBenergy level, in physics, any discrete value from a set of values of total energy for a subatomic particle confined by a force to a limited space or for a system of such particles, such as an atom or a nucleus.
Energy level - Wikipedia
WEBA quantum mechanical system or particle that is bound —that is, confined spatially—can only take on certain discrete values of energy, called energy levels. This contrasts with classical particles, which can have any amount of energy. The term is commonly used for the energy levels of the electrons in atoms, ions, or molecules, which are ...
Energy Level - Principal Quantum Number | Bohr's Atomic Model | Physics
WEBBohr developed an atomic model of a hydrogen atom. Bohr’s model provided a proper clarification for the stability of electrons revolving in fixed orbits. He termed these orbits as energy shells. Different orbits in which electrons revolve are called energy levels or stationary states.

WEBSep 20, 2022 · What Are Energy Levels? Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. Electrons are tiny, negatively charged particles in an atom that move around the positive nucleus at the center. Energy levels are a little like the steps of a staircase.
Energy Level and Transition of Electrons - Brilliant
WEBIn this section we will discuss the energy level of the electron of a hydrogen atom, and how it changes as the electron undergoes transition. According to Bohr's theory, electrons of an atom revolve around the nucleus on certain orbits, or electron shells.
Energy Level: Concept of Energy Level, Formula, Bohr model
WEBEnergy level refers to a fixed distance from an atom’s nucleus where electrons may exist. An energy level is a certain discrete value of energy. The common use of the term ‘energy level’ is for the energy levels of the electrons in atoms, molecules, or ions whose bounding takes place by the nucleus’s electric field.

WEBApr 25, 2022 · In a classical Bohr model, electrons have discrete quantities of energy, called energy levels, as they orbit the central nucleus. An atom is thought to contain several "shells" in which electrons orbit the nucleus, and each shell represents a …
Energy Level: Definition, Equation (w/ Diagrams) - Sciencing
WEBDec 28, 2020 · Energy levels are energy values that an electron in an atom can have or occupy. The lowest energy state or energy level is called the ground state. Since the electrons are attracted to the positively charged protons in the nucleus, they will generally fill the lower energy levels first.
Energy level - Vocab, Definition, and Must Know Facts - Fiveable
WEBAn energy level is a specific quantized state that an electron can occupy in an atom, defined by a set of quantum numbers. Each energy level corresponds to a certain amount of energy, and electrons can transition between these levels by absorbing or emitting energy in the form of photons.
