pblokkiin
The p-block, or p-block region, of the periodic table comprises the elements whose outermost electrons occupy p orbitals. In most modern layouts, this block lies to the right of the s-block and includes the elements in groups 13 through 18, with helium not considered a p-block element. The defining feature is that the last electron enters a p orbital.
The p-block spans multiple periods, from period 2 to period 7 in standard tables. It contains a
Properties within the block vary considerably. Bonding can be covalent or ionic, and compounds span a wide
Applications and significance are broad. Carbon underpins organic chemistry and biochemistry; silicon dominates modern electronics and
