Cadmium.<\/p>\n<p>Potassium, sodium, and lithium are all alkali metals that react violently with water to produce hydrogen gas. Cadmium, on the other hand, is a transition metal that does not react with water.<\/p>\n<p>Alkali metals are very reactive because they have a single valence electron in their outer shell. This electron is easily lost, which makes alkali metals highly electropositive. When an alkali metal is placed in water, the water molecules surround the metal and form a hydration shell. The hydrogen atoms in the water molecules are attracted to the electronegativity of the metal, and they are pulled away from the oxygen atoms. This results in the formation of hydrogen gas and hydroxide ions.<\/p>\n<p>The reaction of alkali metals with water is very exothermic, meaning that it releases a lot of heat. This heat can cause the water to boil and the metal to melt.
