Free Web Service - Periodic Table

Question

Hi,

I was wondering whether someone would be so kind as to show me how to use a web service.

I understand you use Add Service Reference > http://www.webservicex.net/periodictable.asmx?WSDL

But from this point i have no idea what to do and was wondering if you could help.

Even if you could just show me one simple function it would be most appreciated.

Thanks in Advance

PS. Im using VS 2010 Pro and a Win Form
