Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom.
The four quantum numbers, the principal quantum number (n), the angular momentum quantum number (l), the magnetic quantum number (ml), and the spin quantum number (ms) have strict rules which govern the possible values.
Identity allowable combinations of quantum numbers for an electron. Select all that apply.
a) n = 3, l = 2, ml = −2, ms = −1/2
b) n = 4, l = 0, ml = 1, ms = −1/2
c) n = 3, l = −2, ml = −2, ms = +1/2
d) n = 5, l = 4, ml = 4, ms = +1/2
e) n = 3, l = 3, ml = 1, ms = +1/2
f) n = 2, l = 1, ml = 0 ,ms = 0

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
