2. Protons: Identifying Elements

EXPLORE:

The periodic table of elements contains all the known elements found on Earth. They are all made up of atoms, but then how are they different. Each element has a different number of protons in its nucleus. The number of protons is also known as the atomic number.

Directions: Click on the elements below to learn more about their properties.

APPLY:

When you change the number of protons, electrons, and neutrons of an atom, its properties change. The elements combine together in different proportions to make up all matter. Realize that as the element changes the number of protons changes. The number of protons determines the identity of the element.

Directions:

1. Pick an element from the periodic table that is not already posted by your peers on Padlet below.

2. Identify the number of protons and the element's symbol.

3. Post your element and its details by clicking the + in the right corner.

4. Find a connection between your element and one of your classmates. It could be that they form a compound together, they belong to the same group, and so on.

5. Hover over your post and click on the ... to connect your element post to a classmate.

6. Make sure to add your similarity as a comment.

REFLECT:

In your portfolio, reflect on the patterns of the number of protons as you move across the periodic table. What was the main idea of this section? Add your ideas to your portfolio in any form you prefer.
