Question

Then, using information from the “Atomic Zoom-In” article, explain why two substances have different properties to a member of your household.

You may work with more than one member of your household.
You might need to explain a little about what properties are and the different properties the two substances have in order for your household member to be able to work with you.
When you are finished, ask the person what she learned about properties. Record the answer below.
What did your household member learn about properties?

Answer 1

Answer: Two substances have different properties because they are made of different types and numbers of atoms that repeat.

Explanation: According to the article “Atomic Zoom-In”, all matter is made of tiny pieces called atoms, and there are 118 different types of atoms in the universe. Every substance is made of a unique combination of atoms, which can be represented by a chemical formula. The chemical formula shows the types and numbers of atoms that repeat to make up a substance.

For example, water has a chemical formula of H2O, which means it is made of groups of 2 hydrogen atoms and 1 oxygen atom. Substances have different properties because they are made of different types and numbers of atoms that repeat.

For example, water and ethanol are both clear liquids, but they have different properties such as boiling point, density, and flammability. This is because water is made of H2O groups, while ethanol is made of C2H6O groups.

The different types and numbers of atoms affect how the molecules interact with each other and with other substances, resulting in different properties. Therefore, to explain why two substances have different properties, we need to look at their chemical formulas and see how their atoms differ.

Hope this helps, and have a great day! =)
