New bonds formed! Poetry in motion!

Lots of energy released when metals like magnesium bond with oxygen!

Ionic Bonding Poem – a snippet of chemical poetry

(anon Y11 student, Whitby Community College, Oct 31st 2002)

How do I long for a full outer shell!

being chlorine having seven, is a horrid hell

but my name is sodium and I have one spare!

I want to lose it, can we not share?

No? for are we not a perfect match

chuck it to me, I promise to catch

then we can live our separate ways

and live with full shells to the end of our days!

and so our tale comes to an end

as positive and negative we shall remain friends
