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.

What is the valency of sulphur in hydrogen sulphide?
The valency of sulfur in hydrogen sulfide is 2. This means that sulfur in hydrogen sulfide forms two bonds with other elements or ions, such as hydrogen in this case.
How chemical symbol of sodium zincate is formed by valency?
The chemical symbol of sodium zincate is Na2ZnO2. It is formed by balancing the valencies of sodium (Na), zinc (Zn), and oxygen (O). Sodium has a valency of +1, zinc has a valency of +2, and oxygen has a valency of -2. By combining these elements in the appropriate ratios, the compound is represented by Na2ZnO2.
Is hydrogen more active than Zinc?
Hydrogen is more reactive than zinc. Hydrogen reacts readily with many elements, while zinc is considered moderately reactive. Hydrogen's reactivity is seen in its ability to form compounds with a wide range of elements, while zinc tends to form compounds with a more limited subset of elements.
What is the valency of zincate?
Zinc has a valency of 2. It is represented by the symbol Zn.
What elements are in this chemical reaction Zn s HCl g ZnCl s H?

What valency is Hydrogen?
The valency of hydrogen in one.
How does valency of element with respect to hydrogen vary in a period?
in a period from left to right valency of elements with respect to hydrogen increases from 1 to 4 and then decreases upto 1 and with respect to oxygen increases from 1 to 7.
What is the valency of ZnO2 in Na2ZnO2?
The valency of ZnO2 in Na2ZnO2 is 2. This is because Zinc (Zn) typically has a valency of +2, and since there are two oxide ions (O2-) associated with the Zinc in this compound, the overall valency of ZnO2 is +2.
What is the valency of zincate?
Zinc has a valency of 2. It is represented by the symbol Zn.
What is the valency of hydrogen sulphate?
The valency of hydrogen sulfate is -1. It has the chemical formula HSO4-.
What are examples of elements with one as their valency i.e.give examples of monovalent elements.?
Examples of monovalent elements include hydrogen, sodium, and potassium. These elements have one valence electron, which allows them to easily form ions with a +1 charge.
What is the valency of all 2A elements?
All 2A elements show the valency of two.
What is the valency of the smallest element?
the smallest element is hydrogen of which its valency is one.
Radical - positive and negative radical in chemistry?
Valency is the number of hydrogen atoms that can combine with [or displace] one atom of the element [or radical] to form a compound. For example, one atom of hydrogen combines with one atom of chlorine to form hydrogen chloride [HCl]; so, the valency of chlorine [chloride] is one. Similarly, the valency of the nitrate radical [NO3] in the compound nitric acid [HNO3] is 1, and the valency of the sulfate radical in the compound sulfuric acid [H2SO4] is 2. For elements that do not combine with hydrogen, the valency is the combining power of the element with another element whose valency is known. Valency may also be defined as the number of electrons that an atom donates or accepts to form the duplet state (i.e., 2 electrons in outermost shell) or octet state (i.e., 8 electrons in outermost shell). The valency of an element [or radical] is always a whole number. Elements [or radicals] with valency one are monovalent, those with valency two are divalent, and those with valency three are trivalent
