hey mate here is your answer..

When metals react with oxygen, specifically an oxygen atom, the process of oxidation takes place, hence it's name. ... In short, when metals react with oxygen, the metal atoms tend to lose electrons to the oxygen atoms, changing their oxidation state and characteristically their colour..

• magnesium + oxygen → magnesium oxide
• magnesium + oxygen → magnesium oxideiron + oxygen → iron oxide
• magnesium + oxygen → magnesium oxideiron + oxygen → iron oxidecopper + oxygen → copper oxide

hope this answer helps you..❥❥❥❥

Answer 2

Answer:

Many metals react with oxygen to form metal oxides. The general equation for this reaction is: metal + oxygen → metal oxide

Potassium and sodium are soft metal which are easily cut exposing a shiny surface which changes to dull rapidly. The change from shiny to dull is called tarnishing.

Explanation:

2Mg + O2 = 2MgO

magnesium + oxygen → magnesium oxide

Iron + Oxygen = IronOxide

Fe + O2 = Fe2O3
