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 electron could have quantum numbers n4 i2 mi-2 ms-12?
The provided quantum numbers appear to be inconsistent or incorrect. In quantum mechanics, the principal quantum number ( n ) must be a positive integer, while the azimuthal quantum number ( l ) (denoted as ( i ) in your question) should be an integer where ( 0 \leq l < n ). Additionally, the magnetic quantum number ( m_l ) must range from (-l) to ( l), and the spin quantum number ( m_s ) can only be ( +\frac{1}{2} ) or ( -\frac{1}{2} ). Given that ( i = 2 ) is not a valid azimuthal quantum number for ( n = 4 ) (where ( l ) can only be 0, 1, 2, or 3), and that ( m_s ) is incorrectly given as (-12), the electron described by these quantum numbers does not exist.
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 the relationship between principal quantum number and nodes?
The principal quantum number (n) indicates the energy level and size of an electron cloud in an atom. As n increases, the number of nodes, or regions where the probability of finding an electron is zero, also increases. Specifically, the number of nodes in an orbital is given by the formula (n - 1), which includes both radial and angular nodes. Thus, higher principal quantum numbers correlate with more complex electron distributions and increased node counts.

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 total number of electrons inan electron shell is reepresented by the formula 2n . is this correc?
The maximum number of electrons in a shell / energy level is given by 2n2.
Why 2d and 2f orbitals are not possible?
The 2d and 2f orbitals are not possible because of the constraints imposed by quantum mechanics and the principal quantum number (n). The principal quantum number n specifies the energy level and size of the orbital, and for any given n, the maximum angular momentum quantum number (l) can only take values from 0 to n-1. Therefore, for n=2, l can only be 0 (s orbital) or 1 (p orbital), making the 2d and 2f orbitals non-existent.
