A hydrogen carbonate ion has the formula HCO3- so the valency of a hydrogen carbonate ion is -1.
I'm betting on hydrogen phosphide (hydrogen which has a valency 1 combines with phosphide which has a valency 3)
valency of lithium - 1
"Hydrogen has +1 valency and chlorine has -1 valency. So, they share a single electron and form a single covalent bondbetween them. "Chlorine is -1, meaning it has one extra electron. Hydrogen is +1, meaning it requires one electron to fill its valence (if only) shell. therefore HCl is an ionic bond where hydrogen is stealing one electron from chlorine.
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 .
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.
Hydrogen has a valency of 1

Hydrogen has a valency of one, meaning that a lone hydrogen atom is looking to pair up with one other atom of something-or-other; until it does, it has a positive electrical charge, but once that atom has paired up with another hydrogen atom (which will have also had a positive charge) the valency of both is satisfied, & so the bonded pair become neutral.
-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)
Possible valencies: +1, 0, -1.
it does. for example in H2O oxygen has a valency 2 while in hydrogen peroxide H2O2 oxygen exhibits valency 1
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.
The valency of an ammonium ion is 1 (positive).
Hydrogen is Positive.
