Answer to Problem 85A

The element is Zinc.

Explanation of Solution

Even though ionic compounds are formed of ions, they have no electrical charge. The total negative charge of an anion is equal to the sum of the positive charges of cations.

Since the ion has 28 electrons, the element would have 30 electrons without loss of electrons.

The ionic compound formed is ZnCl2 .

The positive charge on zinc is two which is equal to the sum of one anion in each chlorine atom.

(b)

Interpretation Introduction

Interpretation : The number of neutrons present in the ion is to be identified.

Answer to Problem 85A

The number of neutrons present in the ion is 36.

Explanation of Solution

Even though ionic compounds are formed of ions, they have no electrical charge. The total negative charge of an anion is equal to the sum of the positive charges of cations.

Since the ion has 28 electrons, the element would have 30 electrons without loss of electrons.

The number of electrons in the element is 30.

The mass number given is 66.

The number of neutrons is the difference between the mass number and the number of electrons.

So, the number of neutrons is 36.
