"1 metal" is not a meaningful phrase in the context of chemistry or materials science.

It's like asking "what is 1 color?" You need to specify which metal you're talking about.

Here are some examples of metals:

* Gold (Au)

* Iron (Fe)

* Copper (Cu)

* Aluminum (Al)

* Silver (Ag)

Can you please clarify your question? What metal are you interested in?
