Les ions hydrogénoïdes

a.\(\quad\) n = 2 \(~\) l = 3 \(~\) m = 2\(\quad\) impossible car l ne peut être supérieur à n

b.\(\quad\) n = 2 \(~\) l = 1 \(~\) m = 0\(\quad\) possible

c.\(\quad\) n = 2 \(~\) l = 2 \(~\) m = 1\(\quad\) impossible car l doit être strictement inférieur à n

d.\(\quad\) n = 3 \(~\) l = 0 \(~\) m = 0\(\quad\) possible

e.\(\quad\) n = 2 \(~\) l = -1 \(~\) m = 0\(\quad\) impossible car l est positif ou nul

f.\(\quad\) n = 5 \(~\) l = 3 \(~\) m = -1\(\quad\) possible
