# How many quantum numbers are used to describe the energy state of an electron in an atom?

*n* = 2, *l* = 0, *ml* = 0, *ms* = -1/2 Only
the radial function R(r) of the Schrodinger wave function (psi) is
needed to calculate the Energy. The radial function only deals with
the principle quantum number (n). Therefore, only n is required to
find the Energy. As to find the Energy states, one must specify if
we are dealing with a one-electron atom situation or
multiple-electron system. For one-electron atoms, the Energy states
is determined by the principle quantum number (n). For
multi-electron systems, the Energy states depend on both the
principle quantum number (n) and orbital quantum number (l). This
explanation is valid unless we are using very high resolution
spectroscopic techniques, deviations will appear.

### What is a quantum number?

Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.

### What is the definition of quantum number?

Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.

### What is a quantum of energy as defined by quantum mechanics?

The value of the quantum of energy depends on the particulars of the quantum system being modeled. A quantum of energy is a quantity of energy which a quantum system will accept. The energy of a photon can be any value on the continuum, but quantum mechanics predicts that an electron will only absorb certain specific amounts of energy that depend on the electronic forces the electron is exposed to.

### What is gained when an electron moves to a higher energy level?

When an electron is moved to a higher energy level, after absorption, the quantum no longer exists as a separate entity -- its energy has been seamlessly integrated ... into the orbital energy of the electron. If the electon absorbs another quantum, that is likewise integrated seamlessly. if the electron drops down a level toward the nucleus, it emits some of its energy as a quantum, outside the electron, that quantum exists as a photon…

### What are the four main quantum numbers?

The names of the quantum numbers are: Principal Quantum number (n) Angular Momentum Quantum Number (l) Magnetic Quantum Number (m) Spin Quantum Number (+1/2 and -1/2) The "n" gives the energy level of the electron then the "l" which is the sublevel then "m" which tells you which orbital it is in and last "s" which tells you if the electron is going to have a positive or negative 1/2 spin

### What are the difference between energy levels and energy states?

These terms are used to describe quantum particles like atoms. Energy level and energy state are used interchangeably, however, specifically energy level is used to describe physically where an electron is located in an atom and energy state describes the definite activity of the electron. Since the activity of an electron will dictate its location, this is where the terms become to mean nearly the same thing.

### What happens to an electron during a quantum leap?

during a quantum leap an electron transitions from one quantum energy signature to another energy signature by absorbing or admitting a photon of energy in this process the electron simultaneously transitions directly from one electron shell level to a higher or lower electron shell level without moving through the space or time in between the two electron shell levels.

### What is the quantum mechanical model of the atom?

The Quantum atomic model is the most recent model of the atom. it's based on quantum mechanics (mathematical solutions of theoretical equations) quantum numbers are quantum solutions to quantum equations and are used to find the probable position and location of an electron in an atom. the first Principal quantum number identifies which energy level an electron is in. There are 7 possible energy levels in an atom in the ground state (stable) the azimuthal…

### What is law of quantum energy and quantum mass?

In the universe energy, matter and go as per quantum. Energy is released in quantum of photon. Electron has a quantum mass. Proton has quantum mass. Both has a quantum charge. Neutron has a quantum mass. Speed of light is a quantum. Big bang is a quantum event essentially occurring at particular mass. It takes a quantum energy for shifting of electrons from one shell to other. In photo-luminescence light energy is released in quantum.
