Bridge elements are elements that belong to period 2 of the periodic table. They have acquired the name because of a unique characteristic that is , they show resemblance in properties with elements of the next group i.e. elements of the third period. This close resemblance can be due to several physical factors such as comparable atomic radius, electronegativity, the polarization of atoms, etc.
