Ten Factors Howcome Earth 4 Energy Are Greater As Compared To Its Competitors

These elements are harder and denser as compared to alkali metals. However, in case of alkaline earth metals no typical pattern or trend is noticed. These solutions are quite valuable in various chemical processes. Magnesium ranks as the eighth most abundant element in the Earth's crust and seventh most abundant element in the human body. They are shiny and typically white or silvery in colour. In case of alkaline metals, as the atomic quantity increases, the boiling point and melting point are noticed to lower in the group. These six metals also burn with distinctive flames and have unique flame coloration, which is why they are employed in fireworks. This is since the smaller atomic size causes the electrons to be packed far more closely, thereby forming powerful metallic bonds. Some are found in the human body, whereas other people are damaging to the human body but helpful for other purposes like radioactive processes and so on. Beryllium has the highest melting and boiling point in the group and Magnesium has the lowest. Nevertheless, this causes the ionization energy to decrease down the group. This is why these metals are harder and denser than alkali metals. The six chemical components that constitute the periodic table are beryllium, magnesium, calcium, strontium, barium and radium. They react with water to form metal hydroxide and hydrogen gas. Reactivity Alkali earth metals are not as reactive as alkali metals, however, they are far more reactive than other components in the periodic table. Because these components have higher reactivity, they are identified in the kind of compounds such as sulfates and carbonates rather of the cost-free kind. Chemically, these elements are strong reducing agents as they have two valence electrons in their valence shell, which they readily give away throughout chemical bond formation. They share several similar characteristics as the alkali metals of Group I in the periodic table, and hence are placed just next to alkali metals. As we move from Be to Ra in the group, it is observed that the atomic radius increases due to the improve in the atomic quantity, quantity of shells and screening effect. The other components of this group also kind oxides when reacted with oxygen. Metallic Character and Density Alkaline earth metals are electro-positive in nature, which increases down the group. Barium and beryllium are poisonous and radium, becoming radioactive it's exposure is dangerous to humans. The most striking resemblance is their high reactivity. Magnesium in its pure form is combustible in nature and burns with an intense white light when brought in get in touch with with air (as it combines with air to type magnesium oxide). They are soft metals but tougher and denser than alkali metals. When freshly reduce, these metals have a gray-white appearance, which is observed to tarnish as quickly as it is exposed to air.

Boiling and Melting Points The temperature at which a solid element turns into liquid state and liquid element into vapor state is named melting and boiling points respectively.
