Either +1/2 or -1/2; the fourth quantum number is ALWAYS either +1/2 or -1/2 and it's not generally possible to say which (other than that two electrons in the same atom which have the same first three quantum numbers will always have different values for the fourth).

What is the second quantum number of the 3p1 electron in aluminum?
The principal quantum number n = 3 and the azimuthal or orbital angular momentum quantum number would be l =1 .l = 1
What is the principal quantum number value for the highest energy electron in carbon atomic number 6?
The principal quantum number for the highest energy electron in carbon would be 2. It is easy to spot this, since carbon exists in row 2 of the period table. The row in which an element resides always shows the highest value of n, or the principal quantum number, that an electron can reside in.
Which quantum number represents the distance between an electron shell and the nucleus?
Based on Heisenberg's uncertainty principle, there is no way possible to have a quantum number for position since the electron's second quantum number already gives you an exact value for its angular momentum.Bohr calculated the most probable radius of the electron cloud (which he mistakenly thought was an actual distance) getting the number 5.29X10-11 m.What I think the asker is speaking of is the quantum number that refers to energy level, n. Though not a physical distance it may be interpreted, using the Bohr model, how "far" away an electron is from the ground state, which some would believe (incorrectly) that this is a function of distance from the nucleus.
Why do two electrons in the same orbital have to have opposite spin states?
Yes. Always. Otherwise they would break the fundamental rules of quantum mechanics, which say that no two electrons can have the same four quantum numbers -- and spin is the 4th quantum number. If two e- are in the same orbital, they share 3 quantum numbers, but the spin quantum number must then be different.
What is the second quantum number for the electrons in the 4p energy sublevel of bromine?
The second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
What is the first quantum number of a 1s2 electron in phosphorus?
The first quantum number (n) represents the energy level (shell), so for a 1s2 electron, it would have a value of 1.
What is the second quantum number of the 3p1 electron in aluminum?
The principal quantum number n = 3 and the azimuthal or orbital angular momentum quantum number would be l =1 .l = 1

Why is it impossible for an electron to have the quantum numbers n3 i1?
I am checking the Wikipedia article on "quantum number", and don't find a quantum number "i" for the electron. If you mean "l", it seems that "l" can be between 0 and n-1. So, for n = 3, l can be between 0 and 2. If this is what you mean, I don't see any reason that would forbid this particular combination.
How big is a quantum leap?
A quantum leap is the smallest possible change that an electron can make in an atom. It involves a discrete jump in energy levels when an electron transitions from one orbit to another. The size of a quantum leap is determined by the difference in energy levels between the initial and final states of the electron.
What are three main parts of an electron's address used in the current atomic theory that describes an electron's location?
I think you are referring to the 3 quantum numbers, n, l m; principal azimuthal and magnetic. Together with the spin quantum number they "define" an electron- but I would hesitate to call this the electrons location- Heisenbergs uncertainty principle gets in the way of a simultaneous knowledge of energy and location.
When would quantum theory change?
when data shows electron energy levels are not related to light wavelengths.
The Quantum Number that defines the probable distance an electron is from the nucleus is the quantum number.?
secondary quantum numberI don't think it is a number, but it could be referring to the Orbitals, being S, P, D, and F. Each orbital is a specific shape and the orbitals are determined in blocks on the Periodic Table. The energy, or Quantum Number would go in front, such as 4p, which means the principal quantum number or energy level is 4 and the orbital shape is p. Hope this helps
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.
Why do two electrons in the same orbital have to have opposite spin states?
Yes. Always. Otherwise they would break the fundamental rules of quantum mechanics, which say that no two electrons can have the same four quantum numbers -- and spin is the 4th quantum number. If two e- are in the same orbital, they share 3 quantum numbers, but the spin quantum number must then be different.
If the electron in a hydrogen atom obeyed classical mechanic instead of quantum mechanics?
It would spiral into the nucleus, emitting x-rays all the way in. Matter would collapse.
