The most reactive metals (those in the first group of the Periodic Table) are called Alkali metals.
I believe that the answer you are looking for is Transition Metals.
Metals that are less reactive than alkali and alkaline earth metals are called transition metals. They are typically less prone to reacting with other elements and have distinctive properties such as variable oxidation states and the ability to form colored compounds.
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 alkali metals, such as lithium, sodium, and potassium, are the most reactive elements in the periodic table. They easily lose their outermost electron to form ions, which leads to their high reactivity.
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.
Assuming "very reactive" to mean spontaneous and energetic in reaction, lower Alkaline metals are among the most reactive.
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
The most reactive non metals are Halogens which may combine most of the metals as well as non metals.
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
These metals are called alkaline earth metals.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
Metals that are non-reactive are called "inert" metals. Metals like Copper (Cu), Gold (Au), Silver (Ag), and to a certain extent Iron (Fe) are some of the most non-reactive metals on the periodic table. However, Tantalum is usually regarded as the most unreactive metal.
the alkali metals are the most reactive... either cesium or francium would be the most reactive out of this group.
in the Periodic Table it is the most reactive metals!
The most reactive metals are in the group 1 of the Periodic Table - the alkali metals.
Alkaline metals (Group 1) are the most reactive metals.
