Potassium is the most reactive. All of the elements in the first column of the Periodic Table are extremely reactive to water. These elements all have on more electron than the stable noble gas configuration (an octet in the valence shell), and so by getting rid of that extra valence electron, the element becomes much more stable. In contact with water, these elements will give this extra electron off to the water, forming hydroxide (OH-) and becoming a positive ion. For example, when you add potassium metal (K) to water, you will form the positive ion K+, which has the same electron configuration as argon, with a completely filled valence shell. The other metals listed will not react very quickly at all with water (unless it is very acidic water).
All are metals.
Some of these metals are: Calcium, Magnesium, Sulfur, Sodium, Potassium, ...
Calcium is more chemically similar to magnesium than to potassium. Both calcium and magnesium are alkaline earth metals, while potassium is an alkali metal. This means that calcium and magnesium have similar chemical properties due to their position on the periodic table.
The reaction between potassium and a dilute acid or even just water (which is what an acid is diluted in) is very dangerous. On contact with the acid the potassium bursts into flame and may even explode, sending flaming molten pieces of potassium into the air.
Potassium and magnesium play vital roles in muscle function, nerve transmission, and maintaining healthy blood pressure levels. Potassium helps regulate fluid balance and muscle contractions, while magnesium supports enzyme function and energy production. Both minerals are essential for overall health and well-being.
All are metals.
These metals are very different.
Main group metals such as sodium, potassium, and magnesium tend to readily combine with chlorine to form ionic compounds known as metal chlorides. These metals typically lose electrons to achieve a full outer shell, while chlorine gains electrons to achieve a stable electron configuration.
Metals which are more reactive than aluminium. Eg= Sodium, Magnesium, Potassium, etc
Potassium bromide can react with elements like chlorine to form potassium chloride and bromine. It can also react with sulfur to form potassium sulfide and bromine. Additionally, it can react with metals like magnesium to form magnesium bromide and potassium.
When potassium, magnesium, and manganese are mixed with water separately, they will undergo different chemical reactions. Potassium will react vigorously with water, magnesium will react slowly to produce magnesium hydroxide and hydrogen gas, while manganese will not react with water under normal conditions.
Potassium and magnesium are not in the same period on the periodic table. Potassium is in the fourth period (row) while magnesium is in the third period. They are both in the same group (column), Group 2, which are known as the alkaline earth metals.

Calcium is more chemically similar to magnesium than to potassium. Both calcium and magnesium are alkaline earth metals, while potassium is an alkali metal. This means that calcium and magnesium have similar chemical properties due to their position on the periodic table.
Potassium, sodium, and lithium are the most reactive metals to water from the options provided. They react vigorously with water, producing hydrogen gas and forming alkaline hydroxides. Calcium and magnesium are less reactive compared to the other three metals when exposed to water.
The reaction between potassium and a dilute acid or even just water (which is what an acid is diluted in) is very dangerous. On contact with the acid the potassium bursts into flame and may even explode, sending flaming molten pieces of potassium into the air.
