Hydrogen is a non metal element. There are 1 electrons in a single atom.
One neutral hydrogen atom contains one electron.
H-H or H:H depending on what you and your professors prefer.
They have a lot of electrons associated with hydrogen Source mastering biology
There are a infinitely growing number of bond pairs between atoms.
Hydrogen contains 1 electron, 1 proton, and 0 neutrons. It is on the periodic table represented by the letter H.
No, the former answer (striked through below this) is very wrong!Hydrogen (elemental H atom) contains only 1 (one!) electron (1s1) and since a H ion (H+) has lost that one to become stable, this H+ ion has no (zero!) electrons at all.Only the very rare and exceptional, negatively charged hydride ion H- ion contains two electrons (1s2 configuration, not favoured, not enough electronegativity)Yes. A Hydrogen atom "wants" to be stable, so it gains an electron to be iso-electronic with helium. After that, its electron configuration is 1s2. H+
There are 20 valence electrons in CH2Cl2. C => 4 e-* x 1 (number of C in chemical formula) = 04 v.e-** H => 1 e- x 2 = 02 v.e- Cl => 7 e- x 2 = 14 v.e- CH2Cl2 = 20 v.e- *e- - this means electrons in short form **v.e- - this means valence electrons in short form
12. Xe has +4 oxidation state in this compound. so if you use VSEPR Theory then you can understand the actual structure and total valence shell does it has.
Lewis dot for H2O2 can be done this way H:O:::O:H well actually it can't O has 6 valence electrons and the way you used only uses 4 the correct way would be H-(:O:)-(:O:)-H Actually they were trying to show a triple bond, not 6 valance electrons. Unfortunately, a triple bond is incorrect. H(:O:)-(:O:)-H is correct due to bond math.

In the dot structure for H2S, there are two hydrogen atoms bonded to a sulfur atom. Sulfur has 6 valence electrons, hydrogen has 1 valence electron, so a total of 8 valence electrons are used in the structure. The sulfur atom has two lone pairs of electrons.
H . . / .. Xe --H / \ H H Something like that. There are 4 lone electrons (or two pairs) and the Xe is bonded to 4 H in this fashion (for some reason the dashes look like they are connected to the lone electrons, but they are not! The are bonded to the Xe). Hope this helps.
