im just learning the quantum model of the atom now and i have a few questions,(adsbygoogle = window.adsbygoogle || []).push({});

1st: why does the different energy levels represented by the primary quantum number n have different numbers of subshells represented by l such as 0,1,2,3. Energy level 1 can only have s or 0 but Energy Level 2 can have 0 or 1 which is s and p. Why is this, what is the difference between the two energy levels that causes this to be possible.

2nd: I dont understand what the m is for, it stands for magnetic or something but im just confused about it, could someone explain that part of the 4 quantum numbers for describing an electron.

Thanks in advance.
