My children love the Julia Donaldson story, ‘The Stick Man’ but did you know that we had our own chemical stick man.
Apparently it exists…..

Atomic Orbitals Viewer
This website is pretty useful for helping students to visualise orbitals.
Not dead easy to use ….. you may be better off using it as a demo in a lesson, rather than giving it directly to the students.

It’s all gone quiet
Sorry for my recent lack of blog posts – we have just had an inspection and focus has been elsewhere…… That said, I hope that normal business will now apply once again!
I always keep an eye on Geoff Neuss’ blog for ‘Inthinking‘ – it makes good reading. One of his recentish postings was made with regards to the curriculum review of Chemistry.

Topic 3: Periodicity – Trends in the Frist Ionisation Energies
Perhaps the most important part of the periodicity topic is the the trends and patterns in first ionisation energies both down a group and across a period. This is found under section 3.2.2 and 3.2.3 of the syllabus.
It builds on the ideas we covered yesterday – namely, the electron arrangement in the atom, as well as shielding of the outer electrons by the inner shells, the distance of the outer electrons from the nucleus and the number of protons in the nucleus. It is therefore improtant that your students are secure in these ideas.

Topic 3 – Periodicity – Trends in the Atomic Radii
Yesterday I dealt with electronegativity. Once your students are secure in this concept, you will be able to expand upon your teaching of this topic.
Section 3.2.2 and 3.2.3 of the syllabus deals specifically with trends both across period 3 and down group 1 and 7.
