Can Orbitals be described using 3 quantum numbers?
More or less. If you mean "orbital" in the sense "those things that can hold two electrons", then yes. A bound electron in an atom can be described by four quantum numbers, one of which is the spin and has two possible values, so any given "orbital" can be described by 3.The three are: n - Principal (shell), n > 0 l - azimuthal (subshell: s, p, d, f, g, h, etc.) n > l >= 0 m - magnetic (specific orbital within a subshell), -l <= m <= l
The principal energy level that consists of one s orbital and three p orbitals has a quantrum number of?
Its Principal quantum no is 2
Who hypothesized that only two electrons can occupy an orbital?
The bottom-line answer is because that is how nature works! However, there are somewhat less profound explanations, but they are really just rules which say that this must happen -- and don't ultimately answer "Why?". The Pauli Exclusion Principle says that all electrons in an atom must have four unique quantum numbers -- no two can have all four the same. This rule forbids more than 2 electrons existing in the same orbital because there are two possible quantum numbers available for that orbital -- electron spin of +1/2 and -1/2. But again, this rule just says that there can't be more than 2 electrons per orbital because of the uniqueness of quantum numbers -- but it doesn't say why quantum numbers must be unique! In the end, it really just is the way it because that's the way it is!
How many quantum numbers?
n = 2, l = 0, ml = 0, ms = -1/2 Only the radial function R(r) of the Schrodinger wave function (psi) is needed to calculate the Energy. The radial function only deals with the principle quantum number (n). Therefore, only n is required to find the Energy. As to find the Energy states, one must specify if we are dealing with a one-electron atom situation or multiple-electron system. For one-electron atoms, the Energy states is determined by the principle quantum number (n). For multi-electron systems, the Energy states depend on both the principle quantum number (n) and orbital quantum number (l). This explanation is valid unless we are using very high resolution spectroscopic techniques, deviations will appear.
What are the possible values of the magnetic quantum number?
The magnetic quantum number, ml, runs from -l to +l (sorry this font is rubbish the letter l looks like a 1) where l is the azimuthal, angular momentum quantum number. The magnetic quantum number ml depends on the orbital angular momentum (azimuthal) quantum number, l, which in turn depends on the principal quantum number, n. The orbital angular momentum (azimuthal) quantum number, l, runs from 0 to (n-1) where n is the principal quantum number. l= 0 is an s orbital, l= 1 is a p subshell, l= 2 is a d subshell, l=3 is an f subshell. The magnetic quantum number, ml, runs from -l to +l (sorry this font is rubbish the letter l looks like a 1). ml "defines " the shape of the orbital and the number within the subshell. As an example for a d orbital (l=2), the values are -2, -1, 0, +1, +2, , so 5 d orbitals in total.
What is amotic orbital?
Atomic Orbital is a math funciton which utilizes quantum mechanics. Atomic Orbital represents three-dimensional volume and indicates where an electron will be found.
Can two electron have the same set of quantum number?
Pauli's exclusion principle
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.

This element is bromine (Br).
Main energy levels?
Quantum numbers specify the properties of atomic orbitals and the properties of electrons in orbitals. The first three quantum numbers result from solutions to the Schrodinger equation. They indicate the main energy levels, the shape, and the orientation of an orbital.-source: "Modern Chemistry" text book Pg.107
What quantum number is a whole number?
The first three quantum numbers (principle, angular momentum, magnetic) are all whole numbers. The last quantum number (spin) is either ½ or -½.

Do electrons travel in pairs?
Electrons do not travel in pairs. An atomic or molecular orbital can hold a pair of electrons, which is probably what you're thinking of. The reason for this is that electrons are fermions: two electrons in an atom or molecule cannot have the exact same quantum state. Specifying the orbital uses up 3 of the 4 quantum numbers for describing an electron's quantum state; the last quantum number is the spin angular momentum which can either be +1/2 or -1/2, so two electrons per orbital. After that it's full and no more electrons can go into that orbital. Note that far from "traveling in pairs", fermions really don't like to be even that close to each other. If there are three orbitals at the same energy level, one electron will go into each before they start to "double up".
As many as four electrons can occupy the same orbitals?
No. Electrons are fermions, meaning they cannot share the same set of four quantum numbers. Usually when we say "orbital" we only mean the first three, so there is room for two electrons in an orbital (corresponding to the two possible ms values).
