Among the elements listed in the question, potassium, by a large margin, is most reactive.
Iron does not react with potassium hydroxide under normal conditions because iron is a less reactive metal compared to potassium. Potassium hydroxide is a strong base that can react with more reactive metals such as aluminum and zinc, but typically not with iron.

Iron is considered a moderately reactive metal. It reacts slowly with oxygen in the air to form iron oxide (rust), but it doesn't react as vigorously as highly reactive metals such as sodium or potassium.
Potassium is the most reactive, followed by caesium, and then calcium. This is because reactivity generally increases moving down Group 1 of the periodic table due to decreasing ionization energy and increasing atomic size.
potassium, gallium, mercury, francium, plutonium.
Potassium is the most reactive. It is in the 1st group. It is an alkaline metal.
Potassium is the most reactive element among potassium, iron, and aluminum. It is a highly reactive metal that easily forms compounds by losing one electron to achieve a stable electron configuration.
no, potassium.

Answer is potassium. You have seen silver,iron and aluminium. You must not have handled potassium.
Sodium is more reactive than either magnesium or iron.

Metals are elements, such as Iron (an element) and Copper (also an element), and they react for various reasons.
Yes, potassium is more reactive than iodine. Potassium is a highly reactive alkali metal, while iodine is a nonmetal that is less reactive. Potassium reacts vigorously with water and air, while iodine is less reactive under normal conditions.
The element in the same group as lithium (Group 1) and the same period as iron (Period 4) is potassium.
Iron has the strongest metallic bond among potassium, lithium, and iron. This is because iron has a higher atomic number and more closely packed electrons, leading to stronger metallic bonding within the iron element.
In this reaction, sodium metal will replace iron in the iron chloride, forming sodium chloride and iron metal. This is an example of a single displacement reaction, where a more reactive element displaces a less reactive element in a compound.
