The number of different HCl molecules possible from the combination of 35 Cl, 37 Cl, 2 H and 3 H atoms need to be deduced Concept introduction: Atoms are composed of fundamental subatomic particles: protons, neutrons and electrons and are characterized by atomic mass and atomic number . Atomic mass = number of protons + number of neutrons. Atomic number = number of protons = number of electrons. Isotopes are atoms of the same element which have the same atomic number but different atomic masses.

Question

Chapter 2, Problem 50E

Interpretation Introduction

Interpretation:

The number of different HCl molecules possible from the combination of ³⁵Cl, ³⁷Cl, ²H and ³H atoms need to be deduced

Concept introduction:

Atoms are composed of fundamental subatomic particles: protons, neutrons and electrons and are characterized by atomic mass and atomic number.

Atomic mass = number of protons + number of neutrons.

Atomic number = number of protons = number of electrons.

Isotopes are atoms of the same element which have the same atomic number but different atomic masses.

Interpretation Introduction

Interpretation:

The first and second most abundant isotope of the possible HCl molecules needs to be identified.

Concept introduction:

Isotopes are atoms of the same element which have the same atomic number but different atomic masses.

Isotopic abundance refers to the amount of a particular isotope present in a given element or a compound.
