NEET Chemistry The p-Block Elements – Group 13 to 18 Elements & Properties

The p-Block Elements are elements in which the last electron enters the p-orbital of the valence shell. These elements belong to Groups 13 to 18 of the modern periodic table and include metals, non-metals, metalloids, and noble gases.

This chapter is highly important for NEET Chemistry and frequently contributes direct and conceptual questions.

Classification of p-Block Elements

The p-block consists of:

Group 13: Boron Family
Group 14: Carbon Family
Group 15: Nitrogen Family
Group 16: Oxygen Family
Group 17: Halogens
Group 18: Noble Gases

Important Concepts

Electronic Configuration

The outermost electrons of p-block elements occupy the p-orbital, which influences their chemical behavior and bonding characteristics.

1 / 0 100%

Periodic Trends

Properties such as atomic size, electronegativity, ionization energy, and metallic character show regular trends across the groups and periods.

Important Compounds

Many compounds of p-block elements are industrially and biologically important, including ammonia, nitric acid, sulfuric acid, and various halogen compounds.
