What does the principal quantum number tell you?
The principal quantum number, denoted by ( n ), describes the main energy level of an electron in an atom. It indicates the average distance of the electron from the nucleus and the energy level of the electron. An increase in the principal quantum number corresponds to the electron being in a higher energy level and farther away from the nucleus.
What quantum number of the hydrogen atom comes closest to giving a 31--diameter electron orbit?
The quantum number that determines the size of an electron's orbit in a hydrogen atom is the principal quantum number, denoted by "n." For an electron orbit with a 31 Å diameter, the closest principal quantum number would be n = 4, because the average radius of the electron for an orbit corresponding to n is approximately given by n^2 Å in hydrogen atom.
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 information is needed to find the general shape of an orbital?
To determine the general shape of an orbital, you need the quantum numbers associated with the electron, particularly the principal quantum number (n) and the azimuthal quantum number (l). The principal quantum number indicates the energy level and size of the orbital, while the azimuthal quantum number defines the shape (s, p, d, f). The values of l correspond to specific shapes: s orbitals are spherical, p orbitals are dumbbell-shaped, and d orbitals have more complex geometries. Additionally, the magnetic quantum number (m_l) can provide information about the orientation of the orbital within a given shape.
What is the relationship between n and the total number of sublevels in a main energy level?
An electron in an atom is described by four quantum numbers:n, the principal quantum numberl, the azimuthal quantum numberml, the magnetic quantum numberms, the spin angular momentum quantum numberThe principal quantum number is a positive integer: 1, 2, 3, etc.The azimuthal quantum number is a non-zero integer: 0, 1, 2, 3, etc.The relationship between n and l is that l must always be strictly less than n. So, for n=1, the only permissible l value is 0. For n=2, l can be 0 or 1. So the number of types of orbitals per level is equal to n.The relationship between l and ml is that ml is an integer between -l and +l. There are 2l+1 values of ml for any given value of l.Since each n, l, ml triple specifies an orbital, if you work it out it turns out that there are n2 orbitals with a given principal quantum number n.Each orbital can have two electrons (ms = +1/2 or -1/2), so there are twice that number of electrons.
All of the orbitals in a given electron shell have the same value of the?
Principal quantum number.
Is Magnetic quantum number ever larger than the principle quantum number?
No, for any given electron, the principle quantum number will be larger. For example, a second shell, p-subshell electron will have the quantum numbers {2, 1, ml, ms} where mlcan be -1, 0, or 1 and, as always, ms can be ½ or -½. The largest ml can be is +1, which is smaller than the principle quantum number, 2.
Which quantum number is also called sub-shell quantum number?
The azimuthal quantum number (l) is also known as the sub-shell quantum number. It represents the sub-shell of an electron within a given energy level. The value of l determines the shape of the orbital (s, p, d, f).
What is the angular nodes formula used to calculate the number of angular nodes in a given system?
The formula to calculate the number of angular nodes in a system is n-1-l, where n is the principal quantum number and l is the azimuthal quantum number.

What is an azimuthal quantum number?
The azimuthal quantum number, denoted by l, determines the shape of an orbital and ranges from 0 to n-1 for a given principal quantum number n. For example, when l=0, the orbital is an s orbital, l=1 corresponds to a p orbital, l=2 represents a d orbital, and l=3 signifies an f orbital.

The maximum number of electrons in a shell / energy level is given by 2n2.
How many electrons can possess this set of quantum numbers... principal quantum number 4... angular quantum number 2?
10 electrons.The angular momentum quantum number is l (small L). This quantum number is dependant on the principal quantum number, and has values, 0 1,2 ..(n-1), where each value of n refers to a subshell known to chemists as followsn= 0, s orbital; n=1, p orbital; n= 2, d orbital; n= 3, f orbital.So we are looking at the d orbitals.There are five d orbitals, with magnetic quantum numbers running from -l to +l, that is -2, -1, 0, +1, +2Each of these can hold 2 electrons (with spin quantum numbers -1/2, +1/2)So we have 10 electrons that can have pricipal quantum numbers of 4 and angular monmentum quantum number of 2.
