Elements IIa of the periodic system of elements are characterized by very similar characteristics but there are big differences between sodium carbonate them. They have the same structure of the peripheral sodium carbonate electron layer, sodium carbonate and the presence of two electrons sodium carbonate in the peripheral layer affects their reactivity and their properties. Are very reactive in nature and is found only in the form of compounds. Different are widespread in nature. While some of them are very widespread others are found in very small quantities. By way of bonding with other elements also differ. Beryllium sodium carbonate with other elements and binds covalently polar covalent bond and all other building compounds Ionic bond. As for the importance of these elements for human and there are great differences between them, while some of them participate in the construction of plant and animal sodium carbonate life others are very harmful to them. Each molecule of chlorophyll, for example, contains magnesium ion, Mg 2 +. Without chlorophyll there would be no photosynthesis, and thus not many other forms of life. Calcium ions, Ca2 +, are an important component of bones, teeth, plants, shells of marine organisms, etc. The aim of this paper is to analyze the general characteristics of alkaline earth metals, the similarities and differences between them and their compounds, as well as analysis of their characteristics affect the use and significance for man. How to position in the periodic system sodium carbonate of elements, electron affinity, ionization energy, the size of the radius of atoms and ions affect the properties and reactivity of Group IIa elements of the periodic table? As the properties of the compounds of these elements are changing and affecting their use and importance to man?
Elements IIa of the periodic system of elements are called alkaline earth metals. Name comes from the fact that their oxides alchemists called "country", and they are in aqueous solutions react strongly alkaline, like oxides of alkali metals. This primarily refers to the oxides of calcium, strontium and barium. In IIa group of the periodic system of elements sodium carbonate include the following elements: beryllium (Be); magnesium sodium carbonate (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). The compounds of calcium limestone and gypsum have been known and used in ancient times. Metal beryllium are isolated and Velero Bisi independently 1828th year. Bisi got it the action of potassium on beryllium chloride -. Devi was isolated in 1808. Was an amalgam of magnesium, magnesium electrolysis - sulfate, using a mercury electrode as the cathode. In compact form given by the French chemist sodium carbonate Bisi 1828th action of potassium sodium carbonate to magnesium chloride sodium carbonate -. Devi gave him the name magnijum (called magnesium from magnesium = - oxide). It was later named magnesium. Calcium is first received Devi 1808th year electrolysis of molten calcium - chloride. Name given by Devi from the Latin word calx meaning lime or calcium - oxide. Strontium has also received Devi 1808th year electrolysis strontium "country" (strontium), which was first discovered by Crawford 1790th year. The name comes from the town of Strontian, Scotland. sodium carbonate Barium is first received Devi 1808th year but not in its pure form by electrolysis of salt. In its pure state is obtained sodium carbonate only 1,901th or 1929th year and won him the French chemist sodium carbonate Guncam. The name comes from the Greek word βαρύς meaning "heavy." The existence of radium is assumed Mendeleev in 1871. Was revealed by M. Curie 1898th year and it was the first radioactive sodium carbonate element to be discovered. Continue reading ..
