#### Answer

See the answer below.

#### Work Step by Step

From definition: $0\leq\ell\leq n-1$ and $-\ell\leq m_\ell\leq \ell$. a) $n=4, \ell=2$ means 4d subshell and $m_\ell=-1$ means it's the second in energy level. b) From definition $n^2=25$ orbitals, $n-1=4$ subshells labeled s, p, d, f and g. c) From definition $2\ell+1=7$ orbitals per subshell, with $-3\leq m_\ell\leq3$
