Group 2 elements are referred to as “ alkaline earth ” metals (tan column below). The name “ alkaline ” comes from the fact that compounds of these elements form basic (pH greater than 7) or alkaline solutions when dissolved in water. If the Group 1 elements all have one electron in their outer orbital, we can predict that the Group 2 elements will have two electrons in that outer shell.

Alkaline earth metals melt at such high temperature that they remain solids ("earths") in fires. Also these metals provide a good example of group trends in properties in the periodic table, with well-characterized homologous behavior down the group.
Sep 07, 2019· Properties of the Alkaline Earth Metals . The alkaline earths possess many of the characteristic properties of metals.Alkaline earths have low electron affinities and low electronegativities.As with the alkali metals, the properties depend on the ease with which electrons are lost.The alkaline earths have two electrons in the outer shell.
Metals & Non-Metals > Alkali and Alkaline Earth Metals . Cesium metal obtained from its ore and Uranium ore. Cesium is found in the minerals pollucite and lepidolite. The abundance of cesium in the Earth's crust has been estimated at about 1 to 3 parts per million. Cesium is used in atomic clocks, which are incredibly accurate.
Anderson (2005) reported extractions for various metals after leaching a range of As-and Sb-containing materials in an alkaline sulphide solution for 6 h at 105°C. The leach media was prepared by

Apr 23, 2019· 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 this article, we will explain the electronic configurations, ionization enthalpy, hydration enthalpy and atomic, ionic radii and other physical and chemical properties of the group one alkali metals.
All alkaline earth metals are placed under group number 2 and s-block of periodic table. These metals are somewhat reactive at standard conditions. Alkaline earth metals appear shiny, silvery-white and are found in the earth's crust. They can be easily distinguished from the other metals
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).They are harder and less reactive than the alkali metals of Group 1A. The name comes from the fact that the oxides of these metals

Alkali metals or Group 1A elements belong to a common group due to its ns 1 valence electronic configuration. The properties of an element have periodic dependence on its atomic number but not
Interesting Facts about Alkaline Earth Metals. They burn with various colored flames as follows: beryllium (white), magnesium (bright white), calcium (red), strontium (crimson), barium (green), and radium (red). The name "alkaline earths" comes from an old name for the oxides of the elements. They are called alkaline
Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit.Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.. The grade of ore
