Calcium is a soft gray Group 2 alkaline earth metal, crust. Alkaline earth metals had a striking resemblance to other known alkalis, such as soda ash or potash, so they were classified as such. For example with lead it is used to make ‘white metal … It occurs naturally in many forms as marble, limestone, chalk, coral calcite etc. Mg-Al alloys are used in construction of aircrafts. The alkaline earth metals are the second group of metals on the periodic table.They are related to the Alkali metals, but they do not react as much because they need more energy to remove their two electrons, So they do not have to be stored in petrol.As ions they have a charge of +2a. Alkali metals group [Group 1A] Alkali metals group is located on the maximum left side of the modern periodic table.It is the first group of s-block, Despite the presence of hydrogen at the top of the group (1A), It is not one of the alkali metals but it is one of the nonmetals because it has a small atomic size and it is a gas.. General properties of alkali metals 3. Other alkali metal … The properties of an element have periodic dependence on its atomic number but not on atomic weight. Because of its low atomic number and very low absorption for X-rays, it is used as radiation windows for X-ray tubes and X-ray detectors. M + H 2 O H 2 + M(OH) 2 (all alkali metals can reduce water to produce hydrogen gas, except Be) Note – Be has least reducing nature among alkaline earth metals. While most metals form arsenides, only the alkali and alkaline earth metals form mostly ionic arsenides. Be is used in the manufacture of alloys. Lithium metal is used to make useful alloys.
