n-1 is the max l
Principal quantum number.
n = 2
The first quantum number of a 2s electron in phosphorus is the principal quantum number, which specifies the energy level of the electron shell. For a 2s electron, the principal quantum number is 2.
An electron in an atom is described by four quantum numbers:n, the principal quantum numberl, the azimuthal quantum numberml, the magnetic quantum numberms, the spin angular momentum quantum numberThe principal quantum number is a positive integer: 1, 2, 3, etc.The azimuthal quantum number is a non-zero integer: 0, 1, 2, 3, etc.The relationship between n and l is that l must always be strictly less than n. So, for n=1, the only permissible l value is 0. For n=2, l can be 0 or 1. So the number of types of orbitals per level is equal to n.The relationship between l and ml is that ml is an integer between -l and +l. There are 2l+1 values of ml for any given value of l.Since each n, l, ml triple specifies an orbital, if you work it out it turns out that there are n2 orbitals with a given principal quantum number n.Each orbital can have two electrons (ms = +1/2 or -1/2), so there are twice that number of electrons.
The quantum numbers of calcium are: Principal quantum number (n): 4 Angular quantum number (l): 0 Magnetic quantum number (ml): 0 Spin quantum number (ms): +1/2
The four quantum numbers for germanium are: Principal quantum number (n) Azimuthal quantum number (l) Magnetic quantum number (ml) Spin quantum number (ms)
The four quantum numbers are: Principal quantum number (n) - symbolized as "n" Azimuthal quantum number (l) - symbolized as "l" Magnetic quantum number (ml) - symbolized as "ml" Spin quantum number (ms) - symbolized as "ms"
The first quantum number is the principal quantum number, denoted by "n." In aluminum, the 3p1 electron would have a principal quantum number of n = 3, since it is in the third energy level orbiting the nucleus.
Atomic orbitals are regions in space where electrons are likely to be found. The sizes of atomic orbitals increase as the principal quantum number (n) increases. The energy of atomic orbitals increases with increasing principal quantum number and decreasing distance from the nucleus. The shape of atomic orbitals is determined by the angular momentum quantum number (l).
n = 3
the answer is "no".
