Yes, it tarnishes after coming in contact with the air because it gradually reacts with oxygen in the air to produce sodium peroxide and sodium oxide. When exposed to water, it produces sodium hydroxide (lye) and flammable hydrogen gas.
Yes.
either potassium, sodium, zinc, iron or copper !
Metal reacting with oxygen is known as oxidation. A common form of this process is found in the rusting of iron, where the iron reacts with oxygen to form iron oxide (known as rust).
Iron oxide is rust. It is formed when the element iron reacts with oxygen in the water or air.

Yes.
It's a displacement reaction as the sodium displaces the iron
2Na + FeO ---> Na2O + Fe
Magnesium, Iron, Copper,sodium and potassium
None of them act violently with water, but the answer is Iron because Copper only reacts with dilute acids.

Water. ---------- Oxygen
Metal reacting with oxygen is known as oxidation. A common form of this process is found in the rusting of iron, where the iron reacts with oxygen to form iron oxide (known as rust).
Rust ( iron hydrated oxides) are formed.
Sodium displaces the sulfate to make sodium sulfate; iron displaces the hydroxide to make ferrous hydroxide which becomes brown.
It takes the oxygen from air because without the presence of air, iron cannot turn into ferric oxide. The iron first reacts with air and then reacts with water to form rust.
