In this activity you will:
• learn about compounds and how they are formed.
• write a paragraph using the facts that you find.

Compounds
• Compounds are formed when atoms of different elements are combined.
•When the elements are combined their identities change.

Water:
• Water is formed from hydrogen and oxygen.
• Both elements are gases.
• When combined they turn to a liquid.
• Hence their identities change.

Analogy:
• Think of elements as letters of the alphabet and compounds as words formed by combining the letters.
• We can spell all of the English words with just 26 letters.
• We can form millions of compounds with just 109 elements.
• Ex: Sodium(Na) + Chlorine(CI) = Salt(NaCI)

Forming Compounds:
• What type of change occurs when forming compounds?
• Chemical changes• Do the characteristics of an element change when
combined with another?• Yes• What happens when 2 or more elements combine
and their properties change?• A compound is formed
