They are extremely reactive with acid -explosively in some cases. They are also very reactive with water and form alkaline solutions and also very reactive with halogens. Apart from that they have the usual properties of metals such as ductility and lustre etc.
The alkaline earth metals and especially barium.
they are harder than alkali metals
highly reactive with alkali metals and alkaline earth metals
Alkaline Earth Metals
Alkali metals and alkaline earth metals differ in their reactivity and properties. Alkali metals are more reactive and have one electron in their outer shell, while alkaline earth metals are less reactive and have two electrons in their outer shell. Additionally, alkali metals are softer and have lower melting points compared to alkaline earth metals.
All alkaline earth metals loss two electrons.
Group 2 metals are classified as alkaline earth metals because they share similar properties: they are shiny, silvery-white, relatively reactive metals with two electrons in their outer shell. They react with water to form alkaline solutions and are generally less reactive than the alkali metals in Group 1.
Group 2A in the periodic table is known as the alkaline earth metals. This group includes elements such as beryllium, magnesium, calcium, strontium, barium, and radium. Alkaline earth metals share similar chemical properties, including being reactive and having two electrons in their outer shell.
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
Alkali metals and alkaline earth metals are both groups of elements on the periodic table, but they have distinct differences in their properties and reactivity. Alkali metals are located in Group 1 of the periodic table and are highly reactive, soft metals that easily lose their outermost electron to form positive ions. In contrast, alkaline earth metals are located in Group 2 and are less reactive than alkali metals, but still have a tendency to lose electrons to form positive ions. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Overall, alkali metals are more reactive and have lower melting points than alkaline earth metals.
Alkaline earth metals have similar properties because they have the same number of valence electrons in their outermost energy level, leading to similar chemical reactivity and bonding behavior. These metals also have similar atomic and ionic radii, which affects their physical properties such as melting points and densities. Additionally, alkaline earth metals share common oxidation states and form similar types of compounds with other elements.
Group 2 elements in the periodic table are the alkaline earth metals.
