What is the valency of zincate?
Zinc has a valency of 2. It is represented by the symbol Zn.
What elements produce hydrogen gas with ammonium hydroxide?
Magnesium, Iron, and Zinc
What is the valency of a hydrogen carbonate ion?
A hydrogen carbonate ion has the formula HCO3- so the valency of a hydrogen carbonate ion is -1.
Which of the following elements are in this chemical reaction Zn (s) HCl (g) ZnCl2 (s) H2?
Zn (zinc) is an element. H (hydrogen) is an element. Cl (chlorine) is an element. H2 (hydrogen gas) is NOT an element.
What is the formula h3p?
I'm betting on hydrogen phosphide (hydrogen which has a valency 1 combines with phosphide which has a valency 3)
What are examples of elements with one as their valency i.e.give examples of monovalent elements.?
hydrogen silver gold
What valency is Hydrogen?
The valency of hydrogen in one.
What is the valency of zincate?
Zinc has a valency of 2. It is represented by the symbol Zn.
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 hydrogen and why?
The valency of hydrogen is +1 because it has a tendency to lose an electron while combining with an Elelment. This gives it a positive valency.
What elements produce hydrogen gas with ammonium hydroxide?
Magnesium, Iron, and Zinc
What is the valency of a hydrogen carbonate ion?
A hydrogen carbonate ion has the formula HCO3- so the valency of a hydrogen carbonate ion is -1.
What is the valency of all 2A elements?
All 2A elements show the valency of two.
Which of the following elements are in this chemical reaction Zn (s) HCl (g) ZnCl2 (s) H2?
Zn (zinc) is an element. H (hydrogen) is an element. Cl (chlorine) is an element. H2 (hydrogen gas) is NOT an element.
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
What is the valency of the smallest element?
the smallest element is hydrogen of which its valency is one.
What is the formula h3p?
I'm betting on hydrogen phosphide (hydrogen which has a valency 1 combines with phosphide which has a valency 3)
