What is the third quantum number of a 3s2 electron in phosphorous 1s22s22p63s23p3?
Zero. First n=3; second l = 0; third m = 0.
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 does a quantum number describe?
n is the first quantum number. It is the principle quantum number. It refers to what energy level it is and will be one greater than the number of nodes in the orbital. l is the second quantum number. It is the angular momentum quantum number and refers to the shape of the orbital. ml is the third quantum number. It is the magnetic quantum number and it refers to the orientation of the orbital. ms is the fourth quantum number. It is the spin quantum number and refers to the magnetic character of the orbital.
Who first wrote the electron wave equation that led to quantum mechanical model?
It was Erwin Rudolf Josef Alexander Schrödinger who first wrote the electron wave equations that led to the Quantum Mechanical model. He formulated it in late 1925, and published was published 1926.

n = 3
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 information does the first quantum number if an electron give?
The energy level an electron gives
What information does the first quantum number of an electron give?
The energy level the electron is in
What is the first quantum number of a 2s2 electron in phosphorus?
N = 2
What is the first quantum number of a 2s2 electron in phosphorus 1s22p63s23p3?
n=2
What does the second quantum number?
It's the azimuthal quantum number. It specifies the angular momentum of the orbital, which can broadly speaking be thought of as its "shape." (The reason I'm putting that in quotation marks is that it's possible for two orbitals with the same azimuthal quantum number to appear rather different in overall shape.)

Which number represents the shape of an electron subshell?
The shape of the electron cloud is determined by the secondary quantum number. The first is n, or the energy level, the second is the sublevel, the third is the specific cloud, and the fourth is the spin.
