what are three chraracteristics of metalloids

and 2 characteristics of noble gases

Since this is not my area of expertise, I searched Google under the key words "metalloids 'noble gases' characteristics" to get these possible sources:

http://en.wikipedia.org/wiki/Metalloid
http://www.scienceclarified.com/everyday/Real-Life-Chemistry-Vol-2/Metalloids.html
http://www.periodic-table.org.uk/metalloids.htm
http://www.periodic-table.org.uk/noble-gases.htm
http://chemistry.about.com/od/elementgroups/a/metalloids.htm

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
