The elements are just the same. If you look at the periodic table, you can see all the metal elements are on the left hand side of the table and all the non-metals are on the right hand side. You can see that there are many more metal elements than non-metal elements. All metals have some things about them which are the same. Here is a summary of all the physical properties of metals.
Metals are usually solid substances at room temperature .
If you want to melt metals, you have to heat them up to a very high temperature - they have a high melting point. An exception to this is mercury. It is one of only two elements which is a liquid, but it still is a metal. Most metals are pretty strong and hard. This strength makes them useful for making things which need to be strong.
