Question

Define Group B elements of the Periodic table.

Answer 1

Group B elements:

• These elements are known as transition metals.
• In a periodic table they are placed in between Group II A and Group III A.
• They provide the transition between the base from the left and acid from the right.
• They have partially filled d sub-shell.
• These include Chromium$\left(\mathrm{Cr}\right)$, Manganese$\left(\mathrm{Mn}\right)$, Copper$\left(\mathrm{Cu}\right)$, Iron$\left(\mathrm{Fe}\right)$, Cobalt$\left(\mathrm{Co}\right)$, Zinc$\left(\mathrm{Zn}\right)$, Silver$\left(\mathrm{Ag}\right)$, Mercury$\left(\mathrm{Hg}\right)$, and Gold$\left(\mathrm{Au}\right)$.

Characteristics of group B elements:

• These are harder and brittle.
• They have a higher melting point and boiling points.
• They are used as a catalyst.
• These metals are unstable and have transition characteristics between s and p block elements.
• They are good conductors of electricity.
