What is the definition of quantum number?
Quantum numbers are values used to describe various characteristics of an electron in an atom, such as its energy, angular momentum, orientation in space, and spin. These numbers are used to define the allowed energy levels and possible configurations of electrons in an atom.
How can you prove that angular momentum is quantized?
Angular momentum is one of three distiguishing properties of motion. It being quatized means that it cannot continuously vary, it varies only in quantum leaps between two set values.
What are the possible values of the magnetic quantum number ml?
The magnetic quantum number ml depends on the orbital angular momentum (azimuthal) quantum number, l, which in turn depends on the principal quantum number, n. The orbital angular momentum (azimuthal) quantum number, l, runs from 0 to (n-1) where n is the principal quantum number. l= 0 is an s orbital, l= 1 is a p subshell, l= 2 is a d subshell, l=3 is an f subshell. The magnetic quantum number, ml, runs from -l to +l (sorry this font is rubbish the letter l looks like a 1) so for an f orbital the values are -3. -2, -1, 0, +1, +2, +3, so 7 f orbitals in total. ml "defines " the shape of the orbital and the number within the subshell.
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.
How does Quantum number indicates the energy level an electron is found?
Quantum numbers help determine the energy level an electron is found in by specifying the electron's orbital. The principal quantum number (n) indicates the main energy level, with higher values corresponding to higher energy levels. Other quantum numbers like azimuthal (l) and magnetic (m) further specify the orbital within that energy level.
What is the second quantum number of a 3p3 elecotron in phosphorus 1s2 2s2 2p6 3s2 3p3?
The second quantum number (angular momentum quantum number) for a 3p electron is 1. This indicates the electron is in the p subshell, which has angular momentum quantum number values of -1, 0, 1.
Which quantum number specifies the direction of an electron's angular momentum?
"l" is known as the angular momentum quantum number. Principal Quantum Number = n Angular Momentum " " = l Magnetic " " = ml Spin " " = ms (Only possible values are 1/2 and -1/2) Search "Permissible Values of Quantum Numbers for Atomic Orbitals" for the values. You basically have to understand the concepts & be able to recreate the chart for tests, otherwise you can blindly memorize it. The chart should be in your book.

What is the relationship between the expectation value of angular momentum and the quantum mechanical properties of a physical system?
The expectation value of angular momentum in quantum mechanics represents the average value of angular momentum that we would expect to measure in a physical system. It is related to the quantum mechanical properties of the system because it provides information about the distribution of angular momentum values that can be observed in the system. This relationship helps us understand the behavior of particles at the quantum level and how they interact with their environment.
Does 2d orbital exist?
In the context of atomic orbitals, the 2d orbital does not exist. The electron orbitals in an atom are defined by three quantum numbers: principal quantum number (n), angular momentum quantum number (l), and magnetic quantum number (m). The angular momentum quantum number (l) can take values of 0 to (n-1), meaning the d orbitals start at l=2, corresponding to the 3d orbitals.
What feature of an orbital is related to the angular momentum quantum number l?
An atomic orbital is a mathematical term signifying the characteristics of the 'orbit' or cloud created by movement of an electron or pair of electrons within an atom. Angular momentum, signified as l, defines the angular momentum of the orbital's path as opposed to values n and m which correspond with the orbital's energy and angular direction, respectively.

The numerical values of the magnetic quantum number m1 depends on the?
The values of the magnetic quantum number depend on the value of the azimuthal quantum number (orbital angular momentum quantum number) and has values -l, .. 0 . ..+l l=1, p orbital, -1, 0, +1 - three p orbitals l=2 d orbital -2, -1, 0., +1,+2 five d orbitals etc.
What are the possible values of the magnetic quantum number ml?
The magnetic quantum number ml depends on the orbital angular momentum (azimuthal) quantum number, l, which in turn depends on the principal quantum number, n. The orbital angular momentum (azimuthal) quantum number, l, runs from 0 to (n-1) where n is the principal quantum number. l= 0 is an s orbital, l= 1 is a p subshell, l= 2 is a d subshell, l=3 is an f subshell. The magnetic quantum number, ml, runs from -l to +l (sorry this font is rubbish the letter l looks like a 1) so for an f orbital the values are -3. -2, -1, 0, +1, +2, +3, so 7 f orbitals in total. ml "defines " the shape of the orbital and the number within the subshell.
