Beryllium
Melting Point: 1287.0 °C Boiling Point: 2469.0 °C
Members of the alkaline earth elements have two electrons in their outermost energy level, giving them similar chemical properties. They are all shiny, silvery-white metals that are relatively reactive and form alkaline solutions when they react with water. They are found in group 2 of the periodic table and have similar physical properties such as high melting and boiling points.
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.
Calcium is considered an alkaline earth metal.
Some examples of metals with low melting and boiling points include mercury, cesium, and gallium. These metals have melting and boiling points significantly lower than traditional metals like iron and copper.
Beryllium has a high melting and boiling point compared to other alkaline earth metals due to its small atomic size and strong metallic bonding. The small size of beryllium atoms allows for more efficient packing in a solid structure, leading to stronger bonds that require more energy to break, resulting in higher melting and boiling points.
Alkaline earth metals do not exist , only alkali earth metals
* alkaline metals contain the higher melting and also the boiling points. * These metals are present in the earths crust which does not have a basic form. * Alkaline earth metals are distributed in structure which is named as rock. * These metals have density which is low. * Alkaline earth metals have low electron affinity and as wells as low electronegativity. * One of the basic characteristic is, it contains two electrons in their outer shell.

Alkali metals have weaker metallic bonding due to their larger atomic size and lower charge density compared to alkaline earth metals. This results in lower melting and boiling points for alkali metals because less energy is required to overcome the forces holding the metal atoms together. Additionally, alkali metals have only one valence electron, making it easier for them to lose this electron and transition into a liquid or gaseous state.
Alkaline earth metals have two valence electrons, while alkali metals have one valence electron. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Additionally, alkaline earth metals are less reactive than alkali metals.
Alkali metals are found in Group 1 of the periodic table and are highly reactive metals with one electron in their outer shell. On the other hand, alkaline earth metals are found in Group 2 and are also reactive but less so than alkali metals, with two electrons in their outer shell. Alkaline earth metals also have higher melting and boiling points compared to alkali metals.
alkali metals are the "mad" elements who explode when exposed to a certain element. for example, sodium cannot be exposed to hydrogen, or it will explode. on the other hand, alkaline earth metals are good conductors, but they do not explode. they also come only from the earth and its crust.
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.
Alkali metals are in Group 1 of the periodic table and are highly reactive, while alkaline earth metals are in Group 2 and are less reactive. Alkali metals have one electron in their outer shell, while alkaline earth metals have two. Alkali metals are softer and have lower melting points compared to alkaline earth metals.
