Study Notes
P-Block Elements
- P-block elements belong to groups 13 to 18 of the periodic table.
- The hallmark of p-block elements' chemistry is the ability to expand their valence shell to accommodate more than eight electrons.
Electronic Configuration
- The valence shell electronic configuration of p-block elements is ns² np¹ to ns² np⁶.
- The valence shell electronic configuration of helium is 1s².
Location in Periodic Table
- P-block elements are located to the right of the s-block and d-block in the periodic table.
Reactivity
- P-block elements are distinguished by their reactivity, which is influenced by the availability of electrons in their outermost energy level.
Group 15 Elements
- Group 15 of the periodic table includes nitrogen, phosphorus, arsenic, antimony, and bismuth.
- Nitrogen is the predominant form of nitrogen in the earth's atmosphere by volume, accounting for about 78% of the atmosphere.
- Phosphorus is a non-metal from Group 15.
- Phosphorus is present in bones as well as in living cells.
- Arsenic is typically grayish-black in color and has a metallic luster under normal conditions.
- Antimony occurs mainly as sulphide minerals.
- Phosphorus is the predominant form of nitrogen in the earth's crust.
- Arsenic is considered a metalloid.
- Phosphate rocks are primarily composed of phosphorus.
