Quantum Numbers | Principal Energy Levels | Energy Sub-levels and Orbitals

Determine whether each of the following sets of quantum numbers 
for the hydrogen atom are valid. If a set is not valid, indicate 
which of the quantum numbers has a value that is not valid: 
(e) n = 2, l = 1, ml = 1, ms = -12

n = 8, l = 3 , mll = 0, ms = 0

n = 7, l = 2, ml = 1, ms = –1/2

n = 9, l = 1, ml = – 2, ms = +1/2

n = 3, l = 0, ml = +3, ms = +1/2

n = 4, l = 2, ml = –2, ms = +1

Which of the following set of quantum numbers is possible?

Quantum Numbers, Atomic Orbitals, and Electron Configurations

A certain orbital of the hydrogen atom has n = 4 and
l = 3. (b) What are the possible values of ms for the orbital?

Give the allowable combinations of quantum numbers for each of the following electrons.
(a) A 4s electron
(b) A 3p electron
(c) A 5f electron
(d) A 5d electron

What is Quantum Spin?

If an electron has n = 2, it possesses only s and p orbitals.

Each orbital within a given atom can hold up to 2 electrons.

The second shell of an atom possesses d orbitals.

A set of f orbitals can hold a maximum of 14 electrons.

The first energy level contains only s orbitals.

Which of the following statements is false?

n = 6, l = 3 , mll = 0, ms = 0

n = 6, l = 2, ml = 1, ms = –1/2

n = 6, l = 3, ml = 0, ms = +1/2

Which of the following set of quantum numbers is possible for an electron in a set of 6f orbitals?

n = 5, l = 3, ml = – 4, ms = +1/2

n = 4, l = 4, ml = +1, ms = +1/2

n = 5, l = 2, ml = +1, ms = +1/2

n = 5, l = 5, ml = – 2, ms = +1/2

n = 5, l = 2, ml = +5, ms = +1/2

Wavelength and Frequency

Wavelength&nbsp;is the distance from one crest of a wave to another, whereas frequency is the number of waves within a second.&nbsp;

The Spin Quantum Number deals with the spin of an electron within an orbital.

Speed of Light

The Speed of Light in a vacuum is related to the wavelength and frequency of a light particle.

Bohr Equation

In the Bohr Equation, the energy and wavelength a photon is related to its energy shell transitions.

Quantum Numbers: Angular Momentum Quantum Number

The&nbsp;Angular Momentum Quantum Number&nbsp;gives the shape of the atomic orbitals.

Emission Spectrum

Emission Spectra is a series of lines formed when emitted light is focused by a slit and passed through a prism. &nbsp;

Introduction to Quantum Mechanics

The 4 Quantum Numbers provide us the coordinates to find the theoretical location of an electron.

Quantum Numbers: Nodes

A node is the region in an atom with zero electron density and where an electron is least likely to exist.

The Energy of Light

The Energy of Light&nbsp;involves the use of a new variable Planck's Constant.

Electromagnetic Spectrum

The Electromagnetic Spectrum is the different forms of radioactive energy that exists in our universe.

Heisenberg Uncertainty Principle

Heisenberg's Uncertainty Principle&nbsp;tries to explain the potential duality of an electron behaving as either a particle or wave.&nbsp;

Quantum Numbers: Number of Electrons

The Quantum Numbers can give both the quantity and location of electrons within a given atom.&nbsp;

Quantum Numbers: Principal Quantum Number

The Principal Quantum Number gives both the size and energy of an electron shell.&nbsp;

Photoelectric Effect

What happens when light strikes the surface of a metal? The Photoelectric Effect&nbsp;can help to explain that.&nbsp;

Quantum Numbers: Magnetic Quantum Number

The Magnetic Quantum Number gives the location of an electron within a specific orbital.

Bohr Model

In the Bohr Model, electrons can move up and down to different orbitals or shells based on absorbing or releasing of energy.&nbsp;

De Broglie Wavelength

The&nbsp;De Broglie Wavelength equation relates wavelength to velocity or speed.&nbsp;
