magnesium (Mg)
The placement of the elements from least reactive to most reactive is xenon, nickel, and then lithium. Xenon is a noble gas and is generally unreactive, while nickel, a transition metal, has moderate reactivity. Lithium, an alkali metal, is highly reactive, especially with water and air.
Not necessarily. The reactivity of a metal does not determine its ease of extraction. Factors such as the abundance in nature, the type of ore it is found in, and the technology available for extraction play a greater role in determining the ease of extraction.
Radium is the least reactive among calcium, magnesium, strontium, and barium. Radium is a highly radioactive metal that readily reacts with other elements, but it is less reactive compared to the other listed elements.
The least reactive is bromine.
Generally, the least reactive elements are the noble gases.

Noble gases, such as helium, neon, and argon, are the least chemically reactive elements. They have a full outer shell of electrons, making them extremely stable and unlikely to form chemical bonds with other elements.

The most reactive metal is francium.
Lithium, (Li) element three and the least reactive of the alkali metals group.
less reactive.beacuse group-1 elements are the most reactive elements.
