Which element has the configuration AR 4s2?
This is because Ar represents 18 atoms, 2 atoms are in 4s2 4 s 2 , a0 atoms in 3d10, and 3 atoms in 4p^3. All the atoms are (18 + 2 + 10 +3) =33. The element with atomic number 33 in the periodic table is Arsenic. Therefore, the given electronic configuration belongs to Arsenic.
