Hydrogen has a valency of 1
there is one valence electron in hydrogen, and it needs one more electron to become stable
Hydrogen has only one electron. Just the one. And it is a valence electron.
The number of valence electrons in cyclopentadiene C5H6 is 54. Carbon has 4 valence electrons and hydrogen has 1, giving a total of 30 for carbon atoms and 24 for hydrogen atoms.
.. H - S - H (please see explanation below)*** .. *****The valence electron pairs are suppose to be on top and on bottom of the sulfur, instead of the hydrogen. This follows the octet rule for the sulfur and the duet rule for the hydrogen.
Hydrogen atoms have one valence electron which is also the only electron they have.
The valence of hydrogen peroxide is -1.
The valence number for Hydrogen is 1. This means that hydrogen typically forms one bond in chemical compounds.
One. A hydrogen atom contains only one electron, and it is a valence electron.
Two. One hydrogen atom has one valence electron, so two hydrogen atoms will have two valence electrons :)

A hydrogen atom has 1 valence electron.
Hydrogen chloride (HCl) has 7 valence electrons. Hydrogen contributes 1 valence electron and chlorine contributes 7 valence electrons.
It's called a valence electron, and there's 1 for a hydrogen atom
H2 is not an atom, it is a diatomic molecule. Each hydrogen atom has 1 valence electron. When two hydrogen atoms covalently bond to form an H2 molecule, there are two valence electrons being shared by the two atoms.
One.Hydrogen has only 1 electron in total, and it is also a valence electron.
HCN, hydrogen cyanide, has a total of 10 valence electrons. Hydrogen contributes 1 valence electron, carbon contributes 4 valence electrons, and nitrogen contributes 5 valence electrons.
Hydrogen doesn't really have a valence shell. It has one electron only.
