The increasing order of the melting point of the element should be identified. Concept Introduction: The atomic radius of a chemical element is a measure of the size of its atoms, the atomic radius is distance from the centre of the nucleus to the boundary of the surrounding cloud of electrons. The atomic radius decreases from left side to right side in the periodic table whereas atomic radius increases from top to bottom in the periodic table. When size of the atom increases the melting point is degreases, therefore the melting point is decreases from top to bottom of 1 and 2 metals groups. Generally the melting point of the alkali metals decreases down the group. This is because as the ions get larger the distance between the bonding electrons and the positive nucleus gets larger and reduces the overall attraction between the two. For similar reasons the electronegativity decreases. The melting point of the alkali metals decreases down the group, because the distance between the bonding electrons and the positive nucleus is larger.
