Presentation transcript:

Draw dot-cross diagrams (like you did at GCSE) for: A lithium atom A sodium atom A potassium atom

Do you think we can review all our ideas about periodicity all in one lesson?

Homework Challenge Question Today To review periodicity and be able to tackle questions Homework A3 exam questions sheet Challenge Question What does the s, p d and f stand for?

Have you drawn something like this?

What is meant by ionisation energy? Can you write this is the form of an equation?

Which electron will be lost 1st?

Sketch a graph of IE vs atomic no. as you go from Li - K

Draw dot cross diagrams for lithium to neon Just show outer shell electrons and the charge on the nucleus

Why do the atoms get SMALLER as you go across this period?

What is meant by ionisation energy again?

Looking at your diagrams of lithium to neon, sketch a graph of how ionisation energy will change with atomic number

But…

Evidence for spd

Typical questions
