properties of alkali earth

Defects of the Long form Periodic Table - 1. The position of hydrogen is still not settled since it shows properties of both alkali metals as well as halogens. 2. Lanthanides and actinides are not accommodated in the main body of the periodic tabl..

The long form of the periodic table is based upon the filling of a particular shell and has been accordingly divided into four blocks i.e. 's', 'p', 'd' and 'f' blocks. The 's' block elements involve the filling of 's' subshell. This block includes the elements of group 1 (or I A) and group 2 (or I..

The melting and boiling point of alkaline Earth metals are characteristically low and do not show regular trends down the group. However these points are higher than the corresponding alkali metals in the same period as atoms of alkaline Earth metals have smaller size..

Alkali and alkaline Earth metals are the most violently active of all the metals. These occur in the combined form with halide, sulphate, carbonate, silicate ions, etc. and are not found in the free state in nature, as these are readily oxidized. A number of alkali an..

Introduction - The long form of the periodic table is based upon the filling of a particular shell and has been accordingly divided into four blocks i.e. 's', 'p', 'd' and 'f' blocks. The 's' block elements involve the filling of 's' subshell. This block includes the elements of group 1 (or I A) an..

Magnesium belongs to group 2 of the periodic table along with other elements like Calcium (Ca), beryllium (Be), strontium (Sr), barium (Ba) and radium (Ra). These elements are called alkaline Earth metals. Due to their smaller size, the electrons are more tightly bound in them and s..

>The modern periodic table is also known as the long form of the periodic table or the extended form of the periodic table. In this table, the elements are arranged in the order of increasing atomic numbers in such away that elements with similar properties fall in the same vertical colum..

Alkaline Earth metals are denser and harder than the alkali metals of group. 1. The comparatively smaller atomic size of alkaline Earth metals leads to more closely packed crystal lattices and hence stronger metallic bonds. This accounts for their increased hardness a..
