How many subshells are possible with (n+1) equal to 6?
Well, there are five subshells POSSIBLE, but only the first two are ACCESSIBLE.
Well... apparently, you want the principal quantum number PLUS ONE to be:
#n+1 = 6#
so the energy level specified, is
#l = 0, 1, 2, 3, 4, 5, 6, 7, . . . , overbrace(n - 1)^(l_max)#
and each of these values of
#color(blue)(l = 0, 1, 2, 3, 4)#
are allowed. Clearly, it means there are FIVE subshells possible (five values of
#s, p, d, f, g#
i.e. there are one
However, only the
