Atomic Model Revision

All matter is made up of

• Matticles

• Atoms

• Only protons

• Helium

When multiple atoms join together to make matter we call it a...

• Carbon

• Really big atom

• Oxygen

• Molecule

What are the three subatomic particles that make up all atoms?

• Protons, neutrons and electrons

• Pringles, Nandos and Eclipse Mints

• Hydrogen, helium and lithium

• Oxygen, nitrogen and helium

Electrons are configured in layers called electron...

Using this table, calculate the correct electron configuration for chlorine, which has atomic number 17 and therefore 17 electrons. Hint: Chlorine is before calcium on the periodic table.

• 2,8,18

• 2,8,8

• 2,8,7

• 2,10,5

Which chemical produced a green emissions spectrum when it was heated in the practical last lesson?

• Sodium Chloride (NaCl)

• Copper Sulfate (CuSO4)

• Potassium chloride (KCl)

• The bamboo skewer.

What was something else you remember from yesterday's lesson that wasn't in the quiz?

How would you rate your own understanding of chemistry so far?

• 1 (I a lost...)

• 2 (I am a bit confused but following a little bit)

• 3 (I am following along but I have some knowledge gaps)

• 4 (I get this!)

• 5 (I could teach the class!)
