Calcium
Group 2 (alkaline earth metals): lithium, sodium, potassium, caesium, rubidium, francium.
No, aluminum is not an alkaline earth metal. Aluminum is a post-transition metal, not an alkaline earth metal. Alkaline earth metals include elements like calcium, magnesium, and barium.
I'm tempted to say; Gramma Tassium...Grampa Tassium...however; http://updatecenter.britannica.com/art?assemblyId=91&type=A shows the Family of 'Alkaline Earth Metals'; Francium, Cesium, Rubidium, Sodium and Lithium NOT, however, Hydrogen, despite it being in the same column!!!
Calcium is considered an alkaline earth metal.
The heaviest alkaline-earth metal is radium. Radium is a highly radioactive element and is the heaviest and most unstable of the alkaline-earth metals.
Potassium is not an alkaline earth metal, it is an alkali metal. The metals in the leftmost column of the periodic table. They are noted for their high reactivity and for the fact that most of their compounds are basic.
Potassium
The third most abundant element that is found in the Earth's Crust is Aluminum.
Group 2 (alkaline earth metals): lithium, sodium, potassium, caesium, rubidium, francium.
The answer is Potassium.
Potassium.

Strontium is not an alkali metal; it is an alkaline earth metal. Alkali metals are Group 1 elements, such as lithium, sodium, and potassium, while alkaline earth metals are Group 2 elements, including strontium.
Yes, alkaline earth metals are reactive to water. When they react with water, they form a metal hydroxide and hydrogen gas. However, their reactivity is lower compared to alkali metals like sodium and potassium.
prety sure that only Potassium (K) and Sodium (Na) can react with calcium. check the reactivity series for more info.
No. Alkali metals such as sodium and potassium are not usually considered contributors to water hardness. The alkaline earth and transition metals (such as calcium and iron) are. Potassium itself is a very soft metal that can be easily cut with a steel knife.
No. All the alkaline earth metals have 2 valence electrons, meaning they have two electrons in the outermost shells. No two alkaline earth metals have the same number of electron shells. Beryllium is the only one with two shells.
