Valency of carbon is 4 and for hydrogen 1
hydrogen always has a valency of +1
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.
The valency of hydrogen in one.
A hydrogen carbonate ion has the formula HCO3- so the valency of a hydrogen carbonate ion is -1.
the smallest element is hydrogen of which its valency is one.
Hydrogen chloride is a neutral compound made of H+ and Cl- ions. Therefore, it has no valency.
I'm betting on hydrogen phosphide (hydrogen which has a valency 1 combines with phosphide which has a valency 3)
Hydrogen sulphide is neutral.
it does. for example in H2O oxygen has a valency 2 while in hydrogen peroxide H2O2 oxygen exhibits valency 1
It all depends on the valency of Hydrogen with other elements.
hydrogen is an alkali metal because it has "one" valency or due to its oxidation no.
Possible valencies: +1, 0, -1.
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
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.
oxidation state is always represented with a positive or negative sign but valency has no sign the valency of hydrogen is one but the oxidation state may b plus 1 or minus 1
elements whose valency is 1.. lyk hydrogen
When hydrogen loses one electron from its 1s atomic orbital, then it forms hydrogen ion. Hydrogen ion only take that atom which has only -1 valency .
hydrogen silver gold
They have 1 valency electron.
-1 hco3-1 all bases are - and most if not all the ones with hydrogen in front are -1 for example- hydrogen sulfate (hso4-1)or hydroxide (oh-1)
Valency relates to atoms not molecules. A valency of one means that an atom can form one bond. Chlorine has 7 electrons in its outer shell, so forming one bond achieves the octet, so it is said to have has a valency of one. In Cl2 there is a single bond. Hydrogen has just one electron in its outer shell so forming a bond gives it a full shell of two like helium, it therefore has a valency of one. In H2 there is a single bond. In HCL there is a single bond. Valency is an old idea, predating Lewis diagrams, octets, and energy levels. It was the number of hydrogen atoms an elemnt could bond to.
