important of metals in human body of alkali metals

When sodium, potassium or lithium is reacted with dry ethanol, the hydrogen atom of the hydroxy group is replaced by the metal atom to form alkoxides. Hydrogen is liberated in the process. The reaction takes place with effervescence. This reaction also serves as an identifiction test..

Traces of metal is necessary for the human and animal system to function efficiently. Some of the important metals required are iron, copper, zinc, sodium and potassium. Iron metal is a constituent of haemoglobin in blood which carries oxygen to var..

>Within the general reactivity or activity series there are some periodic table trends: Down Group 1 (I) the "Alkali Metals" the activity increases Cs > Rb > K > Na > Li. Down Group 2 (II) the activity increases eg Ca > Mg. On the same period, the Group ..

.e., its reaction is fast and more exothermic. This also implies that the reverse reaction becomes more difficult i.e., the more reactive a metal, the more difficult it is to extract from its ore. The metal is also more susceptible to corrosion with oxygen and water. The reactiv..

Introduction - Sodium belongs to Group I in the periodic table. This group is otherwise known as the alkali metals group. Since the atomic number of sodium is 11, its electronic configuration is 2,8,1. Sodium easily loses the lone electron to attain the stable configuration of n..

The specific heat of a substance is an important physical property because it tells us the suitability of a given substance for a specific purpose. Aluminium vessels are used in cooking because aluminium is a light metal. Hence, for a given volume, its thermal capacity will be l..

1. The position of hydrogen is still not settled since it shows properties of both alkali metals as well as halogens. 2. Lanthanides and actinides are not accommodated in the main body of the periodic tabl..

Minerals - Minerals are inorganic nutrients. They include both metallic and non-metallic elements, which are taken by the body in the form of salts. There are 24 elements that are used in our body. They have various functions such as formation of tissues such..

The industrial wastes should be treated before being let into the water bodies. The toxic materials should be removed, the metallic compounds should be precipitated, the acids and alkalis should be neutralized and the temperature of the hot waters should be reduce..
