What is the valency of phosphorus?

Valence of phosphorus: 3, 5 or 6.


Why does periodic table show phosphate having valency of 5 yet it is really valency 3?

You have mistaken Phosphate for Phosphorus. Phosphorus is in Group 5 of the periodic table. Group 5 elements generally have a valency of 3, but it is also possible for them to have a valency of 5... Below are two examples of compounds, one using Phosphorus with valency 5 (V) and one using Phosphorus valency 3 (III) : Phosphate (phosphorus with maximum oxygen) This is formed by Phosphorus (V) + 4 Oxygen. Oxygen has valency -2, thus... 5 + 4 x -2 = 5 - 8 = -3 So we can see that Phosphate has a charge of -3 (or in other words a valency of 3) Phosphite (phosphorus with one less than maximum oxygen) This is formed by Phosphorus (III) + 3 Oxygen, and so... 3 + 3 x -2 = 3 - 6 = -3 So we can see that Phosphite also has a valency of 3 Hope this helps!


Can elements with variable valency can be stored in water?

Yes elements with variable valency can be stored in water. example Phosphorus.


Why does only phosphorus have valency more than 4?

No. Nitrogen does, as well.


Why PCl3 is called phosphorus trichloride but AlCl3 is aluminium chloride?

Aluminium has a valency of 3 and forms a compound called aluminium chloride with chlorine . It is stable . But phosphorus has a valency of 3 and 5. Hence , it is called phosphorous trichloride and phosphorous pentachloride.


What is the difference between sodium and phosphorus oxide?

sodium has valency of +1 while phosphorus has of +3 and +5 so the oxides they form are different and thus have different nature as well.


What is the basicity of phosphorus acid?

3! H3PO3....so its radical's valency is 3....so...eventually H gets 3


Is phosphorus a chemical?

If phosphorous occupie the gallium sites, it would be n type semiconductor since it has more number of valence electrons than gallium and if it occupie the sites of the arsenic sites there is no change since the valency of arsenic and phosphorous be the same


How many electrons does phosphorus have in its valence shell?

The atomic number of phosphorus is 15.its electronic configuration is 2,8,5.outermost shell has 5 electrons. it can accommodate 3 more electrons to complete its octet.so its valency is 3. and it has 5 electrons on its valence shell.
