Valency of phosphorous?
-3 to metals and hydrogen (phophide) +3 in oxo-compounds (phosphite) +5 in oxo-compounds (phosphate)
What is the charge for a group six ion?
The most common charge (or valency) is -2. But there are compounds formed by elements of group VIA with valency from -2 to +6
What is the valency for plumbic?
+4 valency
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!
What is similar about oxygen and lead?
Very little. They can both have a valency of two. They are both elements. They can both form compounds with sulfur. I am reaching here!
What is the valency of Iodine?
1 (in most of the compounds)
Why carbon compounds form covalent compounds?
This because it has the valency 4 (called tetra valency) by which it can combine with lots of elements and also it has a property of forming stable compounds
Why do the nonmetals in group 18 rarely react with other elements to form compounds?
They are the noble gases whose outermost (valency) orbitals are full.
What is the valence atoms of oxygen?
Oxygen has the valency of 2 in most of the compounds.
Valency of phosphorous?
-3 to metals and hydrogen (phophide) +3 in oxo-compounds (phosphite) +5 in oxo-compounds (phosphate)
Is the periodic table a chart of compounds?
No. It's a chart of elements. Compounds are made up of 2 or more elements.
Why does neon have zero valency?
The outer (valance) ring is full.
What is the charge for a group six ion?
The most common charge (or valency) is -2. But there are compounds formed by elements of group VIA with valency from -2 to +6
How many valence electron's is in xenon?
Eight: the valency shell is full.
Why is Hydrogen Lithium Sodium and Potassium are all stacked on top of each other on this chart.?
Assuming that the unspecified chart is the periodic table, the reason is that they all have one electron in their valency shell.
What is the valency of bromine?
Bromine typically has a valence of 1, but it may have a valence 3, 5, or 7 in some compounds.
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.
