. The element zinc in nature consists of five isotopes with higher than0.5% natural abundances, with mass numbers 64, 66, 67, 68, and 70. Write the nuclear symbol for each of these isotopes. How many protons does each contain? How many neutrons does each contain?

Interpretation Introduction

Interpretation:

Interpret the nuclear symbol and number of proton and neutron for isotopes of zinc with mass number 64, 66, 67, 68, 70.

Concept Introduction:

The symbol of element can be shown as Z XA

Where, Z is atomic number or number of proton

A is mass number

Number of neutron = A - Z.

Explanation

Nuclear symbol for isotope of zinc with mass number 64 is 3 0 Zn64 and it contains 30 protons.

Number of neutron = 64 -30 = 34

Nuclear symbol for isotope of zinc with mass number 66 is 3 0 Zn66 and it contains 30 protons.

Number of neutron = 66 -30 = 36

Nuclear symbol for isotope of zinc with mass number 67 is 3 0 Zn67 and it contains 30 protons
