LI 4: We are learning to describe Atoms

Read this website and answer the following questions about atoms:

What is an atom?

A block of particles that mack up our planet. Every atom is different depending of the object.

What is a proton?

A positive charge in the nucleus.

What is a neutron?

Neutrons don’t have a charge. The mass of the neutrons affect the radioactivity.

What is an electron?

A negative charge outside the nucleus.

 Each element has a different number of protons. This is how we tell them apart. They also have different number of neutrons and electrons, but these can change. Helium has 2 protons so its atomic number is 2, it also has  1 or 2 neutrons and 2 electrons. This is different to Lithium which has 3 protons and an atomic number of 3. It also has  3 electrons and 3 or 4 neutrons. Each element has its own symbol.

Fast Rust Task


Work on this Doc together with a partner.

What 3 ingredients are needed for rust to occur.

Water Oxygen (from air) Iron

Write a brief paragraph explaining the rusting process (why rusting occurs)

You have an iron nail, put the nail in a bowl of water. Now what will happen is that the oxygen in your house will mix with the water. Then the water and iron reacts to each other and creates iron oxide aka rust. The iron oxide will continue to eat up the nail until the nail is all eaten up.

How could you prevent something from rusting?

Using as many coats of paint because the paint will cover the rust from spreading. The reason why you need as many layers of paint is because paint can also corrode after 2-4 years.

Another way is by applying wax as it not only makes your vehicle shine, but it also reduces the risk of rusting.

Write 3 sentences explaining something new you’ve learned from this reading.

I learned that rust happens when you put water and air near iron or steel.

An alloy is when a metal is mixed with an element to make the metal stronger.

Write down any new words you found in Fast Rust or the article about rust. Make sure you learn what the word means and write down a definition you understand for each new word.

Word Definition
Corrosion A breaking down of materials due to a chemical action like rusting.
Molecule An amount of a chemical substance. Like solids have molecules that are in a fixed position.
Alloy Mixing elements to a steel to make it harder.
Compound A combination of 2 elements.
Iron oxide The element that makes rust.

Create a word find that includes your new words found in the journal or article.
