Ehamples: valence +1, low density, low hardness, strongly reaction with water, form strong bases, high reactivity.
alkaline metal property
One characteristic property of alkaline earth metals is their tendency to form ionic compounds with a +2 oxidation state. This makes them readily react with nonmetals to form stable compounds. Additionally, alkaline earth metals have relatively low electron affinities, making them less reactive than alkali metals.
they are harder than alkali metals
One characteristic property of alkaline earth metals is their tendency to form 2+ cations during chemical reactions. They also have relatively low electronegativity and reactivity compared to alkali metals.
Shiny metal is a physical property because it can be observed without changing the chemical composition of the metal. It is a characteristic related to how light interacts with the surface of the metal.
