Answer:
1s³ 1p⁹ 2s³ 2d¹ is a possibble when value of l=0 to n
n=1 ⇒ l=0 ,l=1
when, n=2 ⇒ l=0 l=1 l=2
this configuration is possible when each orbital as 3 electrons.
2d ( n+l =4) is filled before 3s (n + l = 3 )
principal quantum number (n) = shell
azimuthal quantum number (l) = sub shell
magnetic quantum nymber (m) = orbirtal
spin quantum number (s) = spin of electron.
