“Write the atomic symbol for each of the following isotopes used in nuclear medicine: a. Copper-64 b. Selenium-75 c. Sodium-24 d. Nitrogen-15” Should be explained Concept introduction: ► Isotopes: The atoms of an element with different mass number or atomic mass are called isotopes. They have same number of protons and electrons but different number of neutrons. Therefore it is not necessary that all atoms of a given element contain the same number of neutrons in their nuclei. For example hydrogen has three isotopes H 1 , H 2 ,H 3 with 0, 1 and 2 neutrons in their nuclei respectively.

Answer 1

Question

Chapter 16.1, Problem 16.7QAP

Interpretation Introduction

Interpretation:

“Write the atomic symbol for each of the following isotopes used in nuclear medicine:

a. Copper-64

b. Selenium-75

c. Sodium-24

d. Nitrogen-15”

Should be explained

Concept introduction:

► Isotopes: The atoms of an element with different mass number or atomic mass are called isotopes. They have same number of protons and electrons but different number of neutrons. Therefore it is not necessary that all atoms of a given element contain the same number of neutrons in their nuclei. For example hydrogen has three isotopes $H^{1} {, H}^{2} {,H}^{3}$ with 0, 1 and 2 neutrons in their nuclei respectively.
