Properties of the Basic Metals Element Group

Metals, shiny solids, are room temperature (except mercury, which is a shiny liquid element), with characteristic high melting points and densities.Many of the properties of metals, including a large atomic radius, low ionization energy, and low electronegativity, are because the electrons in the valence shell of metal atoms can be removed easily.. One characteristic of metals is their ability

Compounds Of Alkaline Earth Metals - Study Material for

Calcium fluoride or fluorospar (CaF 2) is by far the most important of all the fluorides of the alkaline earth metals since it is the only large scale source of fluorine. CaCl 2 is widely used for melting ice on roads, particularly in very cold countries because 30% eutectic mixture of CaCl2/ice freezes at 218 K as compared to NaCl /ice at 255K.
