Gold reacts the least out of copper, gold, iron, and silver. Gold is a noble metal, which means it is less reactive and does not easily corrode or tarnish when exposed to air or moisture. Copper, iron, and silver are more reactive than gold and can form oxides or other compounds more readily.
The discovery of the order of elements calcium, gold, and iron is attributed to their differing reactivities. Calcium is more reactive than gold and iron is less reactive than both. This reactivity trend helps explain why these elements were discovered in that particular order historically.
Zinc is the metal that will replace iron in an iron solution through a displacement reaction because it is more reactive. Copper, gold, and lead are less reactive than iron and would not displace it in a solution.
Yes, silver is more reactive than gold. Silver is more chemically reactive because it has a tendency to form compounds with other elements more readily than gold. Gold is known for its resistance to corrosion and is considered a noble metal.
In a short answer No. But I can't really explain why.
No. Sulfur is more reactive than iron.
Sodium is more reactive than iron because sodium has a higher tendency to lose electrons and form ions compared to iron. Sodium reacts vigorously with water and air, while iron reacts more slowly under normal conditions.
Sodium is more reactive than either magnesium or iron.
When iron is added to gold nitrate solution, no reaction occurs because iron is not reactive enough to displace gold from its nitrate compound. Gold nitrate would remain unchanged.
zinc
Sodium is more reactive than iron(It is above iron in the raectivity series). In fact , it is so reactive that it catches fire when exposed to air.It is stored dipped in kerosene oil.
