Platinum
The least reactive is bromine.
This metal is gold.
Gold
calcium
The most reactive metal is francium.
No, Potassium is one of the most reactive metals.
magnesium (Mg)
The least reactive metal in group 1 of the periodic table is francium. Francium is highly radioactive and has a very short half-life, making it extremely rare and difficult to study its chemical properties.
Gold is the least metal reactive in the list, followed by copper, magnesium, and then potassium. Gold is known for its resistance to corrosion and chemical reactions, making it one of the least reactive metals.
Gold is least reactive with aqueous solutions of metal ions among tin, zinc, gold, and calcium. Gold is a noble metal and does not readily react with most common reagents, including aqueous solutions of metal ions.
Lithium
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.
