1. What we will do What we will learn 10C 15 Mahuru 2017
Quick quiz and preliminaries
How to start well
&
Revisit what ionic compounds are and why they are formed PLUS
Do some examples in class
- extend to complex ions:
What ionic compounds are, why they are formed and how to tackle some examples
Write down the chemical formulae and names of the three main acids used in school labs
What they are and how to write them (both ways)
If time, do more examples from the NCEA1 resource booklet
How to get ready for 2018

4. “Effervescence” is…another name for fizz.
It happens in some chemical reactions, for example, when an acid reacts with a carbonate.
Acid + Carbonate  Carbon Dioxide gas +
some other compounds

7. Atom 3: Lithium
3 protons
3 or 4 neutrons
3 electrons

8. Helium, Neon, Argon and Krypton do not lose or gain electrons
Helium, Neon, Argon and Krypton do not lose or gain electrons. This is because none of them need to gain electrons or lose electrons. They all already have a full outside layer.

9. There are two main types of change: Physical Change and Chemical Change.
A physical change in a substance doesn't change what the substance is. A chemical change, where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed. Chemical Changes are generally MUCH HARDER to reverse than Physical Changes.

10. Examples of Physical Changes:
A piece of paper is folded.
A piece of paper is torn.
A block of ice is melted.
Milk and water are mixed.
Lead is melted to make fishing sinkers.

11. Examples of Physical Changes:
A piece of paper is folded.
A piece of paper is torn.
A block of ice is melted.
Milk and water are mixed.
Lead is melted to make fishing sinkers,
Examples of Chemical Changes:
A cake is cooked.
Toast is burnt.
Vinegar and baking soda make fizz.
Steel goes rusty.
Concrete goes hard after it is poured.
Milk turns into cheese.
Firewood becomes ash when burnt.

12. Discuss the similarities and differences between H, Li, Na and K atoms
They all have one electron in the outside layer
They all react really strongly
They are all flammable. E.g sodium in water and hydrogen in the airship crash
They all form ONE PLUS ions.
They all react by losing one electron
DIFFERENCES
They all have different numbers of layers of electrons
Although they are all very reactive, the bigger ones react more strongly than the little ones.

13. Revisit some ions. Eg H, Li, N, O, F, Na, Mg, Al, P, S, Cl, K, Ca
