#n=2# and #l=0#

Explanation:

A quick revision,

#n# is the principle quantum number and takes values =1, 2, 3, ...

#l# is the azimuthal quantum number and takes the values = 0 to #n-1#

so for;
#n=1#, #l=0#
#n=2#; #l=0, 1#
#n=3#; #l=0, 1, 2#... and so on.
(here, #0# stands for #s#-orbital, #1# for #p#-orbital, #2# is #d#-orbital and so on)

So, the value of #n# and #l# for #2s# orbital would be
#color(blue)(n=2)#, (the #2# from "#2s#") and
#color(blue)(l=0)# (as #0# represents s-orbital)
