Answer
See the answer below.
Work Step by Step
a) energy level
The highof nodal planes.
c) moreer the value of n, the bigger the energy level.
b) $\ell$
Determines the number
Shorter wavelength, since orange is closer to red.
d) 7
$2\ell+1$ orbitals per subshell.
e) 1
The orbital is specified by $m_\ell$
f) left to right: d, s, p
See the number of nodal planes: 2,0 and 1
g) 0 to 4
$0\leq\ell\leq n-1$
h) 16
$n^2$ orbitals per shell.
