Lesson: Ions Chemistry

In this lesson, we will learn how to write and interpret symbols of ions and calculate the ionic charges using protons and electrons.

Lesson Plan

Students will be able to

recall the different charges of the particles that make up an atom,
use the terms anion and cation to describe positive and negative ions,
use the number of electrons lost or gained from an atom to calculate the overall charge of the ion,
explain why atoms have no overall charge,
calculate the number of protons, neutrons, and electrons in atoms and ions,
relate an element’s position on the periodic table to the likely charge of its common ion,
define the charges and names of common polyatomic ions to write accurate chemical formulas.
