Can elements with variable valency can be stored in water?
Yes, elements with variable valency can be stored in water. However, the reactivity of the element will determine how stable it is in water. Some elements may react with water to form oxides or hydroxides, while others may remain stable. It is important to consider the specific properties of the element in question when storing it in water.
Does gold exhibit a variable valency?
No, gold typically exhibits a fixed valency of +1. It commonly exists in its elemental form with a valency of 0 when not bonded to other elements.
What non-metals has no variable valency Zn Cu Fe N?
Out of the non-metals you listed, nitrogen (N) is the only one that does not exhibit variable valency. Zinc (Zn), copper (Cu), and iron (Fe) can exhibit variable valency in certain compounds.
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.
Why does a d-block elements a variable valency?
because they have one valence electron

Does gold exhibit a variable valency?
No, gold typically exhibits a fixed valency of +1. It commonly exists in its elemental form with a valency of 0 when not bonded to other elements.
Why some elements have variable valencies?
Certain elements combine with other atoms, donating, accepting or sharing electrons in different proportions depending on the nature of the reaction. For example, iron combines with oxygen to form ferrous oxide as well as ferric oxide. In the formation of ferrous oxide, iron exhibits a valency of +2, whereas in ferric oxide, it has a valency of +3. This is termed variable valency
Why transition elements show variable valency?
Transition elements contain 2 outermost shells incompleted including the valence shell. But when it reacts with other, it shares,gives or accepts elctrons from its inner shells.
What non-metals has no variable valency Zn Cu Fe N?
Out of the non-metals you listed, nitrogen (N) is the only one that does not exhibit variable valency. Zinc (Zn), copper (Cu), and iron (Fe) can exhibit variable valency in certain compounds.
How are the elements variable valency named?
Elements with variable valency are typically named using Roman numerals to indicate their oxidation states in a compound. For example, iron can have a valency of +2 or +3, and in compounds, it may be referred to as iron(II) for the +2 state and iron(III) for the +3 state. This nomenclature helps clarify which specific ion is present in the compound. Additionally, some elements may use traditional names, such as "cuprous" for copper(I) and "cupric" for copper(II).
What is the valency of all 2A elements?
All 2A elements show the valency of two.
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 do you mean by variable valency?
Variable valencies are the valencies which can change e.g. Fe (iron) can either have the valency of 2 (Fe II) or 3 (Fe III)
What is the valency of helium be?
helium's valency is zero as id does not combine with other elements
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)
