A key concept is:

Compounds are formed by chemically combining two or more elements.

5.2 Q2.  Question?

5.2 Q2

A substance made of atoms from 2 or more different elements, joined by a chemical bond is called a Compound.

Compounds have properties different from their constituent elements.

5.2 Q3.  Question?

5.2 Q3

In the process of Chemical Reaction substances change into new substances. 

Atoms rearrange into new combinations, joining into different patterns. 

This is how new substances are formed.

5.2 Q4 Question?

5.2 Q4

Table Salt

Water

Citric acid

Carbon Dioxide

Baking Soda

The properties of a new compound are different from the properties of the elements that formed the compound.

5.2 Q6.  Question?

5.2 Q6.

In a Compound:

elements join in a specific ratio

according to their masses.

for water:  1 hydrogen to 8 oxygen

Water = 1:8 mass ratio of hydrogen to oxygen

5.2 Q7  Question is?

5.2 Q7

Compounds are broken down by chemical changes.

5.2 Q8  Question is?

5.2 Q8

A Compound found in all living things is Protein.
