metal or a non-metal?





plz answer the question all of them please​

Answer 1

Answer:

The two metals which do not react with oxygen are gold and silver.

Here are some ways where we can prevent rusting :

Paint it - Paint the metal with any durable acrylic paint. ...

Keep moisture at Bay - Avoid contact with water or moisture. ...

Coat it with Oil - Use of oil or grease significantly reduces the chances of developing rust in iron.

a metal made by combining two or more metallic elements, especially to give greater strength or resistance to corrosion.

Alloying allows us to manipulate the properties of a metal by adding other elements to it. For example, adding a little carbon to iron makes it harder and more ware resistant. Adding Chromium to iron (13%) makes it resistant to rust harder (this is called stainless steel), and so on.
