Chapter 11.9, Problem 11.2SC

Interpretation Introduction

Interpretation:

The complete electronic configuration and orbital diagram for each of the elements aluminium through argon should be written.

Concept Introduction:

The distribution of electrons in atom into orbitals is said to be electronic configuration. The electronic configuration for every element present in the periodic table is unique or different. Atomic number is equal to the number of protons, which is further equal to the number of electrons for neutral atom.

The electronic configuration is also denoted by the pictorial representations, known as orbital diagrams. Orbital diagram represents the pairing arrangement of electrons and individual orbitals. The filling of electrons in the orbital is done in the way; first the electrons are filled single in the orbital, after filling the single electron per orbital, if any electron is left in that energy level, then pairing of electrons occurs. Electrons are present with opposite spin in the orbital.
