Nitrogen (N), Phosphorous (P), Arsenic (As), Antimony (Sb) and Bismuth (Bi) all have a valence of 5, meaning they have 5 electrons in their outer shell. This means that they will readily accept three electrons, rather than lose five.

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!

Having more than one possible ionic charge?

Elements that can have more than one possible ionic charge are called elements with variable valency. This can occur when an element has multiple oxidation states, leading to the formation of ions with different charges in chemical reactions. Transition metals are common examples of elements with variable valency.

What are the Valency of elements hydrogen to zinc?

The valency of elements can vary depending on the conditions and compounds they are in. Generally, for hydrogen, it is +1, for elements in groups 1 and 2, it is +1 and +2 respectively, for elements in groups 13-18, it corresponds to their group number. Zinc typically has a valency of +2.


How do you find valency of elements?

The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.

How do you take out valency an element?

Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)


What the valency of So2 and So3?

The valency of SO2 is 4, while the valency of SO3 is 6. The valency of an atom is the combining power of an element, which indicates the number of bonds it can form with other elements.


How do you learn symbols and valencies?

You need to learn the symbols for the elements I am afraid. Start using a Periodic table (see the links below).You could also learn the valencies but if you know the periodic table and understand why elements appear where they do, you can work out the likely valencies from the positions of the elements in the table - they are where they are for a reason!You must ask your chemistry teacher to explain this reasoning to you - it should form part of your lessons.This will helpGroup number 1 = Valency 1group number 2 = valency 2group number 3 = valency 3group number 4 = valency 4group number 5 = valency 3group number 6 = valency 2group number 7 = valency 1group number 8 = valency 0 (noble gases, nonreactive)
