using contraction and expansion
Many infinite sets appear in mathematics: the set of counting numbers; the set of integers; the set of rational numbers; the set of irrational numbers; the set of real numbers; the set of complex numbers. Also, certain subsets of these, such as the set of square numbers, the set of prime numbers, and others.
The validity or invalidity of a function are not abstract but depend on its domain and codomain or range. If for any point, A, in the domain there is a unique point, B, in the range such that f(A) = B then the function is valid at A. The validity of a function can change from point to point. For example, f(x) = sqrt(x) is not a function from the set of Real Numbers to the set of Real Numbers because any negative number in the domain is not mapped to any value in the range. This can be corrected either by changing the domain to the set of non-negative Real Numbers or (if you are a more advanced mathematician) change the range to the set of Complex Numbers. Similarly the reciprocal function, f(x) = 1/x is valid everywhere except for x = 0. Or f(x) = tan(x) is valid except for x = 90+k*180 degrees for all integer values of k - so it is not valid at an infinite number of points.
In a certain sense, the set of complex numbers is "larger" than the set of real numbers, since the set of real numbers is a proper subset of it.
electrical engineers and quantum mechanics use them.
The set of quantum numbers n=1, l=2, ml=0 cannot occur together to specify an orbital. This is because the quantum number l (azimuthal quantum number) ranges from 0 to n-1, meaning l cannot be greater than or equal to n.
Pauli's exclusion principle
The set of quantum numbers for nitrogen can be written as follows: n=2, l=1, ml=0, ms= +1/2 or -1/2. This corresponds to the second energy level, p orbital, zero magnetic quantum number, and either spin up or down.
The four quantum numbers for germanium are: Principal quantum number (n) Azimuthal quantum number (l) Magnetic quantum number (ml) Spin quantum number (ms)
The highest energy electron in Zirconium (Zr) corresponds to the 4th energy level (n=4) with an angular momentum quantum number of l=3 (d-orbital), a magnetic quantum number ml ranging from -3 to 3, and a spin quantum number of ms=+1/2. This set of quantum numbers specifies the 4d subshell in which the electron resides.
1p is not a valid orbital designation according to the rules for assigning quantum numbers to atomic orbitals. Orbitals are defined using the principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m), and spin quantum number (s). The orbital with n=1 and l=1 is designated as 2p, not 1p.
The allowable sets of quantum numbers are n (principal quantum number), l (azimuthal quantum number), ml (magnetic quantum number), and ms (spin quantum number). n determines the energy level and size of an orbital, l determines the shape of an orbital, ml determines the orientation of an orbital in space, and ms determines the spin of an electron in an orbital. Each set of quantum numbers must follow specific rules based on the principles of quantum mechanics.
from Max Planck's theory, quantum numbers are units of energy.
Quantum numbers are a set of 4 imaginary numbers which explain the position and spin of electrons in an atom it can not explain an atom as a whole Iodine has 53 electrons so there are 53 sets of quantum numbers for Iodine.The above is correct. Assuming you meant to ask for the quantum numbers for the last electron added to Iodine, that would be n=5, l=1, m=0, s=1/2.
The quantum mechanical exclusion principle was formulated by Wolfgang Pauli in 1925. This principle states that no two electrons in an atom can have the same set of quantum numbers, preventing identical particles from occupying the same quantum state simultaneously.
The Pauli exclusion principle, which states that no two electrons in an atom can have the same set of quantum numbers. This includes the spin quantum number, which can have values of +1/2 (up) or -1/2 (down). So, in the 1s orbital, the two electrons must have different spin quantum numbers to adhere to this principle.
Four quantum numbers are required to completely specify a single atomic orbital: principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m), and spin quantum number (s). These numbers describe the size, shape, orientation, and spin of the atomic orbital, respectively.
