Why is phosphorus in group 5 periodic table?

Answer 1

Group 5A (or VA) of the Periodic Table are the pnictogens: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi). The name "pnictogen" is not in common usage; it derived from the Greek work pnigein, "choke" or "stifle," which is a property of breathing pure nitrogen gas.

The Group 5A elements have five valence electrons in their highest-energy orbitals (ns2np3). Nitrogen, phosphorus, and arsenic can form ionic compounds by gaining three electrons, forming the nitride (N3-), phosphide (P3-) and arsenide (As3-) anions, but they more frequently form compounds through covalent bonding. Antimony and bismuth can lose either their outermost p electrons to form 3+ charges, or their outermost s and p electrons to form 5+ charges.

Compounds of Group 5 Elements

The title of this lesson doesn't really do the topic justice. Compounds made from elements in Group 5 of the periodic table can help athletes increase endurance and build muscle. They're involved in making chemical weapons used in war. And, you might even them find in your favorite beverages.

Answer 2

Phosphorous atom is an atom of element phosphorous. It contains 15 protons, 15 electrons and

16 neutrons. The phosphorous atom is never found in free state because phosphorous always exists as a polyatomic molecule which is P4.

Answer 3

* Name: phosphorus * Symbol: P * Atomic number: 15 * Atomic weight: 30.973762 (2) * CAS Registry ID: 7723-14-0 * Group number: 15 * Group name: Pnictogen * Period number: 3 * Block: p-block

Answer 4

No. Phosphate is not on the periodic table, as it is a group or ion involving two elements (phosphorus and oxygen).

Phosphorus, however, is on the periodic table.

Answer 5

Phosphorus belongs to Group-15 and Period-3 in the modern periodic table.

Answer 6

Phosphorus is placed i group-15. its period number is 3.
