Chapter 5, Problem 5.120SP

Interpretation Introduction

Interpretation:

The increasing order of atomic radius of S, F and O needs to be determined.

Concept introduction:

An atom consists of three sub-atomic particles; electrons, protons and neutrons. The Bohr’s model purposed the concept of energy levels around the nucleus. It was first most accepted atomic model. The quantum mechanical model is based on certain concepts like quantum numbers, Heisenberg uncertainty principle, etc. The atomic structure can be described with the help of these principals and atomic models.

All known elements are placed in the periodic table according to their atomic number. The atomic number of elements increases from left to right by 1 unit in the periodic table. The vertical columns of periodic table are called as groups.
