Solubility: The solubility of the sulphates in water decreases down the groups i.e. Metal halides are compounds between metals and halogens.Some, such as sodium chloride are ionic, while others are covalently bonded. The elements in Group 2 are called the alkaline earth metals. Alkali metals have only a weak tendency to form complexes with simple Lewis bases. All nitrates are soluble. Atomic radius increases down the group Mg–Ba Explanation: the number of shells of electrons increases in each element as the group is descended. are solved by group of students and teacher of NEET, which is also the largest student community of NEET. 6.8k SHARES. The alkali metals react with halogens (group 17) to form ionic halides; the heavier chalcogens (group 16) to produce metal chalcogenides; and oxygen to form compounds, whose stoichiometry depends on the size of the metal atom.

However, due to transit disruptions in some geographies, deliveries may be delayed. 1. MgO is basic and Mg(OH)2 is weakly basic and do not dissolve in NaOH solution. The sulphates of alkaline earth metals are all white solids. Covalently bonded metal halides may be discrete molecules, such as uranium hexafluoride, or they may form polymeric structures, such as palladium chloride.. Alkali metals belong to the s-block elements occupying the leftmost side of the periodic table.Alkali metals readily lose electrons, making them count among the most reactive elements on earth. In order to prevent the corrosion, alkalis are added as the neutralization reagent, which result in generation and precipitation of alkali metal salts. In association with Nuffield Foundation. Data on some, such as cesium and rubidium fluoride, nitrate, carbonate, and sulfate, appear to be reported for the first time.
