Chapter 4, Problem 89CP

(a)

Interpretation Introduction

Interpretation:

The number of protons, neutrons and electrons in Sr-87 needs to be determined.

Concept Introduction :

The atomic number represents the number of electrons revolving round the nucleus in an atom. It also represents the number of protons in the nucleus of an atom.

The sum of the number of neutrons and protons in the nucleus of an atom represents mass number.

(b)

Interpretation Introduction

Interpretation:

The most abundant isotope in a strontium sample needs to be determined.

Concept Introduction :

From the given set of isotopes of an atom, the most abundant isotope will have maximum percentage abundance.

(c)

Interpretation Introduction

Interpretation:

The number of neutrons in Sr-84 needs to be determined.

Concept Introduction :

The atomic number represents the number of electrons revolving round the nucleus in an atom. It also represents the number of protons in the nucleus of an atom.

The sum of the number of neutrons and protons in the nucleus of an atom represents mass number.

(d)

Interpretation Introduction

Interpretation:

This is to be explained why any isotope of strontium does not have atomic mass of 87.62 amu.

Concept Introduction :

Atomic mass of any element listed on periodic table is average atomic mass of all its isotopes and it is calculated by taking average of product of atomic mass and percent abundance of isotope of that element.
