202-- How many of the following statements are correct?
Every sublevel is identified by the quantum numbers $n$ and $l$.
In filling sublevels, only the principal quantum number is relevant.
From the relation $a = 4l + a$, the electronic capacity of sublevels ($a$) can be determined.
In the atom $_{29}$Cu, the ratio of electrons with $l = 0$ to $l = 2$ is $0.7$.
