What is need of Spin quantum number?
The spin quantum number was created in the early twentieth century to account for the magnetic properties of the electron. It has only two possible values, +1/2 and -1/2, which indicates the two possible spin states of the electron. A single orbital can hold up to 2 electrons, which must have opposite spin states.
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.
If the principle quantum number is 3 what possible values can azimuthal quantum number have?
For a principle quantum number 3, there are three possible sub-shells. These are 3s, 3p, 3d. Azimuthal quantum no. is less than principle quantum number. There for 3s it is 0, for 3p it is 1, for 3d it is 2.
How many possible values are there for the spin quantum number?
two --- + 1/2 or - 1/2
How many possible values are there for spin numbers?
the spin quantum number has only two possible values__(+ 1/2 & -1/2)
How many orbitals in the fourth energy level?
The atomic states with principal quantum number 4 can have orbital angular momentum quantum numbers from -4 to 4. Hence there are 9 possible values of the orbital angular momentum quantum number. Each electron can have spin +1/2 or -1/2, so each of the states specified by a given orbital angular momentum quantum number can have at most two electrons in the state without violating Pauli's exclusion principle. So, in sum, there are 18 possible states for an electron with principal quantum number 4.
What are the possible values of ml for an electron in a d orbital?
2,1,0,-1,-2 are the possible values of ml for an electron in d orbital.
How many electrons can have the quantum numbers n 5 ℓ 0 ml0?
There can be two electrons with those quantum numbers in an atom. Each electron is completely described by four quantum numbers. The one that's missing in the list provided is ms, which can have only two possible values (+1/2 and -1/2).
What is the difference between two isotopes of an electron?
There is no difference. Electrons are subatomic particles and therefore identical.Added:In the same orbital, defined by one 'tri' set of quantum numbers (n, l, and ml ) the spin quantum number differs, the two values being ms = +1/2 and ms = -1/2, are each taken by one electron.
A quantum of energy as defined in the Quantum Mechanical Model is a?
It isn't so much a matter of there being a given "quantum of energy" as much as energy is quantized. This means that particles that behave quantum mechanical laws can only have certain values of energy and not the values in between. The most popular example of this is an electron in an atom. Quantum theory tells us that the electron can be in it's ground state energy, which has a given value, or it's first excited state, which has another given value, or any higher excited state. However, you cannot observe an electron with an energy value in between the ground state and first excited state, or between any two consecutive excited states. This is what it means to have quantized energy: only certain discrete values are allowed.
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 would the fourth quantum number of a 1 S 2 electron be?
Either +1/2 or -1/2; the fourth quantum number is ALWAYS either +1/2 or -1/2 and it's not generally possible to say which (other than that two electrons in the same atom which have the same first three quantum numbers will always have different values for the fourth).
