Week 10 Highlights - End of term mayhem to look forward to

As we've now know how metals bond with non-metals and how non-metals bond with other non-metals it looks like we only have one more type of bond to look at which is obviously the bond between metals and metals, called metallic bonding strangely enough.

This week we'll finish off looking at covalent bonds and look at some different covalent structures and compare these with ionic structures. The properties of ionic and covalent molecules will be related to their structure then the properties of metals will be explained by looking at metallic bonding.

Before we begin next week it may be a good idea for you to all get familiar with the various properties of metals, so that nothing comes as a surprise to you next week.

As we finish week 9, we'll investigate how the structure of molecules defines their properties by looking at allotropes of sulphur and carbon, and seeing how diamond and graphite compare.

In next weeks lessons, we'll look at Metals in great detail then we'll cover one of the most important topics you have covered so far - the reactivity series.

Now here's the good bit - the reactivity series includes one of the most exciting demos in the whole sylabus - the thermite reaction. This is so dangerous it will involve us taking a lesson outside because it is too dangerous to do inside.

So if we manage to get through all the required work the last lesson of term will be absolutely BRILLIANT!

ummm sir cant you post us some worksheets that we can print out and benefit from because honestly i don't understand anything on this website so worksheets would be better and easier !!!!!!!!

hey sillycon,
'metal and non-metal' bonding is ionic bonding and 'non-metal and non-metal' bonding is covalent bonding.

Anonymous is absolutely right. Non-metals combine with other non-metals by covalent bonding. They SHARE an electron. Each atom has to share one (or two to make a double bond) electron(s) so their atoms 'overlap'

Ionic bonds are formed between 2 ions of metal and non-metal. The opposite charges attract each other.
