Answer : The element is Arsenic (As).
Explanation :
The given electronic configuration is [tex]4s^24p^3[/tex] which means the lower shells are fully-filled.
Now the complete electronic configuration is,
[tex]1s^22s^22p^63s^23p^63d^{10}4s^24p^3[/tex]
The total number of electrons = 2 + 2 + 6 + 2 + 6 + 10 + 2 + 3 = 33
From the periodic table, we conclude that the Arsenic is the element which have 33 number of electrons.
