Chapter 3, Problem 3.65AP

a.

Summary Introduction

To determine:

The name and symbol of the ion that has $3$ protons and $2$ electrons.

Concept introduction:

Atomic number is the total number of protons or electrons present in an atom.

A neutral atom consists of the same number of protons and electrons. This corresponds to the atomic number of an element. If the positively charged ion is given then, it has number of protons than electrons whereas if the negatively charged ion is given then, it has more number of electrons than protons.

b.

Summary Introduction

To determine:

The name and symbol of the ion that has $35$ protons and $36$ electrons.
