What does a quantum number describe?
n is the first quantum number. It is the principle quantum number. It refers to what energy level it is and will be one greater than the number of nodes in the orbital. l is the second quantum number. It is the angular momentum quantum number and refers to the shape of the orbital. ml is the third quantum number. It is the magnetic quantum number and it refers to the orientation of the orbital. ms is the fourth quantum number. It is the spin quantum number and refers to the magnetic character of the orbital.
What is the quantum number for helium?
There are several different quantum numbers for a given atom (principle quantum number, the angular quantum number, the magnetic quantum number, the spin quantum number, etc) .I assume you are looking for the Principle Quantum number, n, which is equal to the row (period) in the period table in which the element is situated.For helium, the principle quantum number is 1.i.e. n = 1As another example; the principle quantum number for potassium (K), n = 4.
What are three quantum numbers that correspond to a 5s orbital?
3s has a principle quantum number of n=3 5s has a principle quantum number of n=5
How many electrons have quantum numbers values n l m?
In theory, the number of electrons with each quantum number is not limited. However, for any given "main quantum number" (n), the number of electrons having the other quantum numbers is limited - but it depends on the value of "n". For more information, the Wikipedia article on "quantum number" seems to give a good overview.
Names and symbols of the four quantum numbers required to define the energy of electrons in atoms?
These are: principal quantum number (n), azimutal quantum number (ł), magnetic quantum number (m), spin quantum number (sd).
