The Compound Challenge

The Element/Compound Challenge

In a previous lesson we learned that every atom is made up of 3 sub-atomic particles; protons, neutrons and electrons. We also learned that the electrons on the orbit furthest away from the nucleus are called valence electrons.

​

Atomic Structure

We also learned that elements in the same vertical column are called a group and elements in the same horizontal row are called a period.

​Groups & Periods

Video Response

Challenge #1

You were assigned an element at the beginning of class. Make an intro video based on your element where you give the following info.

-Name

-Number of protons, neutrons and electrons

-Number of valence electrons

-Group number

-Period number

Elements that belong to the same group have the same number of valence electrons (except for group 18). As a result those elements create similar bonds when forming compounds. For that reason, groups in the Periodic Table are also called a "family"

Challenge #2

Find the other members of your family and make where everyone introduces themselves (name only).

Elements in the same period are very different from each other except for one similarity, they all have the same number of electron orbits.

Periods

Challenge #3

Find the members of your period and record a team lineup video.

When 2 or more different atoms combine, they form a chemical bond and create a compound. The compound is represented using a chemical formula. The smallest unit of a compound is a molecule.

​

​Compounds

To create a compound, atoms can for 2 types of bonds. A covalent bond is where valence electrons are shared. An ionic bond occurs when one atom loses an electron which is picked up by another atom.

Challenge #4

Find another atom that you would be able to create a bond with and create a video where you introduce the compound you have just created.
