Electron Affinity
When an element undergoes a chemical reaction, it either gains energy or loses energy. This gain or loss of energy is due to the phenomena that occur at atomic level. During reaction, atoms either gain electrons from other atoms or lose electrons to othe…
P-Block Elements
Elements which are present on the right side of the periodic table are called p-block elements. In addition to the noble gases, they include the families of boron, mercury, nitrogen, oxygen and fluorine. These elements have diverse real-life implementati…
Metals and Non-metals
The periodic table is composed of metals, semi-metals and nonmetal elements. The physical and chemical properties of metals and nonmetals differ from each other. The study of metals and nonmetals will help one to understand the appropriate application of…

Chapter 2, Problem 27E
Interpretation Introduction

Interpretation: The densities of a hydrogen nucleus and a hydrogen atom by using the mass of the proton, the mass of the electron, and the sizes of the nucleus and the atom are to be calculated.

Concept introduction: Density is a ratio relating to the mass of a substance to its volume. It is symbolized by using the symbol ρ and is mathematically expressed by the formula which is as follows;

  Density(ρ)=Mass(m)Volume(V)
