The maximum number of electrons that can be accommodated in a set of orbitals is six. Consequently, there are six groups occupied by the p block elements.
The p-block contains groups 13, 14, 15, 16, 17, and 18, except Helium. The principal quantum number “n” fills the p orbital. There is a maximum of six electrons that can occupy the p orbital.
- First group: group IIIA called as Boron group
- Second group: group IVA, called as Carbon group.
- Third group: group VA called as Nitrogen group.
- Fourth group: group VIA called Chalcogens.
- Fifth group: group VIIA called Halogens.
- Sixth group: zero groups or group 18 called as Inert or Noble gasses group.
In the p-block, all three sorts of elements are available, i.e. the Metals, Non-Metals, and Metalloids.
- Metals: Aluminium,Gallium, Indium,Thallium,Tin,Lead,Bismuth
- Non-Metals: Helium, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Phosphorus, Sulphur, Chlorine, Argon, Selenium, Bromine, Krypton, Iodine, Xenon, Radon
- Metalloids: Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, Polonium, Astatine
