Elements of the periodic table which belong to groups 13 to 18 are called "p-block" because their valence electrons are found in the p orbital. These elements display a wide range of chemical properties.
Here are some major properties of p-block elements:
1. On the right side of the periodic table p-block elements are located.
2. They have valence e- in the p orbital of their (p-block elements) outermost energy level. The no. of valence e- increases across the period from left to right.
3. These elements participate in various chemical bonding, including covalent, ionic, and metallic. Their reactivity depends on their position in the periodic table.
5. Some of the p-block elements exhibit different structural forms called “allotropes”. For example, carbon exists in various forms in nature like graphite, diamond, and many more, each with different properties. Some other elements like selenium, phosphorus, sulfur, etc. also have multiple “allotropes”.
