five basic elements metal

Basic oxides are the oxides of metals. If soluble in water they react with water to produce hydroxides (alkalies) e.g., ..

Basic fluxes like lime (CaO), magnesium oxide (MgO) are used to remove acidic gangue such as SiO 2 ...

Ammonia molecule has a strong tendency to donate its lone pair of electrons of nitrogen to other molecules. Thus, it acts like a strong Lewis base. In aqueous solutions, NH 3 ionizes in accordance with the reaction...

Elements - "An element is a pure substance which is made up of only one kind of atoms having the same atomic number." "The smallest particle of an element is the atom which, has all the properties of that element." "An element..

Metals loose electrons and form positively charged ions, therefore metals are called electropositive elements. Sodium metal forms sodium ions Na + , Mg forms positively charged Megnesium ions Mg 2 + and aluminium forms aluminium ions Al 3 +..

All elements except hydrogen, which form positive ions by losing electrons during chemical reactions are called metals. Thus metals are electropositive elements. They are characterized by bright lustre, hardness, ability to resonate sound and are excellent c..

Acetic acid reacts with strongly electropositive metals like sodium and zinc to give the respective acetate and liberate hydrogen. ..

Besides the above reactions of chlorine with metals, chlorine also undergoes addition reactions with heated metals like aluminium, zinc, iron, etc. to form their chlorides. Metals with variable valencies always form the chloride of the higher metallic valenc..

On the basis of electronic configuration, the elements of the periodic table are classified into: (1) Noble gases, (2) Normal elements, (3) Transition elements, (4) Inner-transition elements, (5) Alkali metals and (6) Halogen..
