(a)

Interpretation Introduction

Interpretation:

The number of protons and electrons present in neutral copper atom has to be given.

(b)

Interpretation Introduction

Interpretation:

The number of protons and electrons present in ${\text{Cu}}^{\text{+}}$ has to be given.

Concept Introduction:

Identifying the number of protons and electrons in an ion:

The number of protons can be determined by identifying the element.  The charge present the number of electrons present in the element.

If a positive charge is present, the number of protons will be more than electrons.

If a negative charge is present, the number of electrons will be more than protons.

(c)

Interpretation Introduction

Interpretation:

The number of protons and electrons present in ${\text{Cu}}^{\text{2+}}$ has to be given.

Concept Introduction:

Identifying the number of protons and electrons in an ion:

Refer to part (b).

(d)

Interpretation Introduction

Interpretation:

The formula of zinc acetate has to be given.
