[ne]3: 23p1
[ne]352302

Al- [Ne] 3s²3p¹

As- [Ar] 4s²3d¹⁰ 4p³

Explanation:

Electron configuration of an element shows the arrangement of electrons in the energy levels or orbitals in the atom.Noble-gas configuration involves use of noble gases to write the configuration of other elements.This is done by identifying the atomic number of the element and then identifying the noble gas that comes before that particular element on the periodic table.For example: Aluminium: The atomic number of Al is 13. The noble gas before Aluminium is Neon which has 10 electrons. Therefore the remaining 3 electrons fills up the 3s and 3p sub orbitals. Thus, the noble-gas configuration of Al is [Ne] 3s²3p¹

     2.  Arsenic, Atomic number is 33

Noble gas before Arsenic is Ar,. Argon has 17 electrons, then the remaining electrons fills up the 4s, 3d and 4p sub-orbitals.Thus, the noble-gas configuration of As is [Ar] 4s²3d¹⁰ 4p³
