Chapter 2, Problem 119IP

Interpretation Introduction

Interpretation:

The number of protons present in sulfur analog of ${\text{Ta}}_{\text{2}}{\text{O}}_{\text{5}}$ should be determined.

Concept Introduction:

The number of proton in a neutral atom is equal to the atomic number of the atom.  The sum of neutrons and protons is equal to the mass number of atom.  In a neutral atom, the number of electrons is equal to the number of protons but in case of ion, they are different.  The charge (positive or negative) on the ion is the difference of number of proton and number of electrons.
