The science of extracting metals from their ores and utilizing them for various useful purposes is called metallurgy. The nature and properties of metals make its extraction difficult by using single method. Thus, it is … Read more
Group 13 of the long form of the periodic table consists of five elements: Boron (B), Aluminium (Al), Gallium (Ga), Indium (In) and Thallium (Tl). All these elements collectively are named as boron group elements, because Boron (B) is the first element of this group. These elements form the first group of the p-block elements. … Read more

The long form of periodic table can be divided into four main blocks. These four main blocks are s, p, d and f –blocks. The division of elements into blocks is purely based upon the electronic configuration. The nature of the subshell in which the last electron of that atom enters, determines the block to … Read more
