When Naming Chemical compounds a chemist must make some edits based on what's reacting. They follow the following rules (write them into your workbook)
Naming Compound rules
1. The metal is always written first
2. The name of the non-metal is changed to incorporate an 'ide' (see below) |
3. Depending on how many of each atom there is in the compound a prefix is added to the non metal as well.
|
4. When there is an oxygen in a compound of 3 or more elements, the suffix changes from "ide" to "ate"

Student Activities
1- Heading in Book: Writing Chemical Equations. 2- Write the following into your workbook. When writing chemical equations chemists follow two main rules. 1. They always write the cation then follow it with the anion. 2. They then use the cross method to help indicate how many atoms are needed to make the compound. |
So.... Let's define some things...
What is a Cation?
What is a Cation?
What do all the numbers around a chemical symbol mean?
Draw the formula above (make it big) - then copy the following:
- The two elements in this formula are Nitrogen (N) and Helium (H).
- The number 4 is small and is located at the bottom right of an element. This number ONLY applies to the element it is connected to. In this case Hydrogen. Therefore there are 4 Hydrogen atoms.
- The number 2 is big and located at the beginning of the chemical formula. This means it belongs to everything in front of it. Therefore there are 2 Nitrogen atoms AND 8 Hydrogen atoms (2 x 4 lots of Hydrogen)
- The +1 is located at the top right hand corner of the formula. This tells us the formula is a cation with a positive charge of 1. This numbers applies to the WHOLE formula before it.

The Cross Method
When we want to find the formula of an ionic compound we use the Cross Method to help us. There are three examples of the cross method that you need to be aware of.

Student Activity:
You are to create a Career Profile for a Biochemist in Australia.
Your Career Profile can be completed in the form of a fact sheet or a poster.
How to complete your Career Profile:
Watch the two videos above to get a general understanding about biochemistry (note: video number 2 is a Canadian video, so salaries and qualifications may differ!!!).
Use the internet to further your research about biochemistry as a career.
In your profile, consider aspects such as:
- What is a biochemist?
- What qualifications do you need in Australia to become a biochemist?
- What areas can a biochemists can operate in? eg Gatorade (athletes)
- What does a typical day look like for a biochemist?
- What are the salaries of a biochemist in Australia?
