electron
A hydrogen ion can change into an atom by gaining an electron. When a hydrogen ion, which is essentially a hydrogen atom that has lost its electron, gains an electron back, it will become a neutral hydrogen atom.
No element is lighter than hydrogen. Not even stripping the electron off a hydrogen atom would make a lighter item, because electrons have almost no mass and the proton would just grab it back anyway.
yes
Hydrogen atoms have one valence electron which is also the only electron they have.
The simplest atom that contains one proton, one electron, and no neutrons is the hydrogen atom.
The hydrogen atom has 1 electron.
There is one electron in a hydrogen atom. Hydrogen has 1 valence electron and is therefore very unstable by itself. Hydrogen is diatomic, which means that it naturally occurs bonded with another Hydrogen atom: H2
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Chlorine is very electronegative and pulls on the hydrogen's single electron, forming a positive end where the Hydrogen atom is, and a negative charge where the Chlorine is. This is because the Chlorine pulls much harder on the electron than Hydrogen does.
The single electron in a neutral hydrogen atom resides in the 1s orbital.
Yes, a neutral hydrogen atom does exhibit an attraction for an additional electron.
None. A hydrogen atom has one proton and one electron (no neutron). Removing the electron leads to just a proton, no electrons.
