Define the term “compound”. Explain that a compound consists of two or more different elements bound
together. A compound has properties that are different from the properties of the elements which compose
them. Bring in salt as example. Sodium is a metal that reacts violently with water. Chlorine is a poisonous
gas. However, when they join to form the compound, sodium chloride (NaCl), they produce a white, edible
solid. Water (H20) is another example. Hydrogen and oxygen are both gases separately, but when they
combine, they form a liquid.
Read about compounds on page 79 of Pearson textbook.
