When do you use roman numerals in an element?
we usually use roman numerals in writing names of compounds of transitional elements which have more than one valency . for example we have two compounds of iron chloride , iron(II)chloride and iron(III)chloride depending on the valency of iron in each compound.
Can a hexagon have more than 8 sides?
No. A hexagon can only have six sides. No more, no less.
Is 657 is 28 more than 685?
Yes, only if you mean 685 is 28 more than 657 because 657+28 = 685
A number having more than 2 factors?
A number that has only two factors is prime. A number that has more than two factors is composite.
Why is 100 a composite number?
Because it has more than two factors whereas a prime number has only two factorsBecause it has more than two factors.
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!
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
Can an element have more than one valency?
yes
Is phosphorus more electronegative than sodium?
Phosphorus is more electronegative than sodium. The electronegativity of phosphorus is 2.19. The electronegativity of sodium is 0.93.
Is carbon more reactive than phosphorus?
NO, not in their pure form. Phosphorus is much more reactive.
Why is the phosphorus cycle slower than the nitrogen cycle?
It occurs more slowly because phosphorus rarely occurs as a gas.
What is more reactive than phosphorus?
NOONE
Which bond is more polar a phosphorus fcholrine bond or a phosphorus fluorine bond?
The bond between phosphorus and fluorine atoms is more polar than the bond between phosphorus and chlorine atoms.
Why is nitrogen more electronegative than phosphorus?
Chlorine is more electronegative than phosphorus. Generally, the trend of the periodic table is that electronegativity increases as you go from left to right, and it decreases as you go down.
Is sulfur more reactive than phosphorus?
Yep :)
Why some elements in the periodic table have more than one valency?
because the valency is no of electrons present in last shell and different element have different electronic configuration.
Is oxygen more electronegative than phosphorus?
According to the Pauling scale, the electronegativity of oxygen is 3.44 while that of phosphorus is 2.19. Therefore oxygen is more electronegative than phosphorus, i.e. the oxygen atom has a greater tendency to attract electrons towards itself than the phosphorus atom. Fluorine is the most electronegative element in the periodic table, with an electronegativity value of 3.98.
