Potassium and sodium.
The 2 most important alkaline earth metals are Calcium and Magnesium
The most important are potassium and sodium.
No, but they are 2 of the most important men in history.
They just are. Fact of life. Like cheese.
The transition elements are placed in center of periodic table. Examples are: zinc and copper
Alkali metals (Group 1) and alkaline earth metals (Group 2) are the most reactive groups of metals. They readily lose electrons to form ions and participate in chemical reactions with nonmetals to achieve a stable electron configuration.
Group 2, or the alkaline earth metals.
There are 2 most general categories. These are metals and non-metals.
The most active metals, including alkali metals and alkaline earth metals, are located in groups 1 and 2 of the periodic table, respectively. Alkali metals are in group 1, while alkaline earth metals are in group 2. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
The most common charge for alkaline earth metals is +2. This is because they have 2 valence electrons, which they tend to lose to achieve a stable octet electron configuration.
Potassium and sodium are the two most reactive metals in the periodic table. They can react vigorously with water and air to form compounds.
Chemical elements can be divided into metals and non-metals. Metals typically have properties like luster, conductivity, and malleability, while non-metals are generally less shiny, poor conductors, and more brittle.
