Introduction

In the realm of chemistry, understanding the behavior of electrons in an atom is crucial for grasping various chemical phenomena. One of the fundamental concepts in atomic physics is the quantum number, which describes the energy, shape, and orientation of an electron's orbital. In this article, we will delve into the calculation of quantum numbers for two specific elements: Z = 37 (Rb) and Z = 35 (Br).

What are Quantum Numbers?

Quantum numbers are a set of four numbers (n, l, m, s) that describe the energy, shape, and orientation of an electron's orbital in an atom. These numbers are used to specify the quantum state of an electron and are essential in understanding the behavior of electrons in an atom.

  • Principal Quantum Number (n): This number describes the energy level of an electron. It can take any positive integer value (1, 2, 3, ...).
  • Azimuthal Quantum Number (l): This number describes the shape of an electron's orbital. It can take any integer value from 0 to n-1.
  • Magnetic Quantum Number (m): This number describes the orientation of an electron's orbital in space. It can take any integer value from -l to +l.
  • Spin Quantum Number (s): This number describes the intrinsic spin of an electron. It can take any value of ±1/2.
