The p-block of the periodic table of the elements consists of the last six groups minus helium (which is located in the s-block). In the elemental form of the p-block elements, the highest energy electron occupies a p-orbital. The p-block contains all of the nonmetals (except for Hydrogen and Helium which are in the s-block) and semimetals, as well as some of the metals.
The groups of the p-block are:
| Nonmetals | Metalloids | Poor metals | atomic number in red are gases | atomic number in black are solids | atomic number in green are liquids | solid borders are primordial elements (older than the Earth) | dotted borders are radioactive, synthetic elements |
