Yes they do.
The matter is if you mean pass as a permanent action or not.
In polar bonds the atoms share their orbitals and the electon pass in both the atoms.
With an ionic bond the more electronegative atom gets the electon and charges negatively, the other gets his electon carried away and charges positively. And this a permanent action which usually generates ionic composites such as Na+Cl-.
Electons run into orbitals (wich are teoric they don't really exists, they are just the representation of the area where the electon spend the 90% of his time).
Orbitals
One - assuming the atom is not an ion.
In one atom of Oxygen there are 8 electrons
A Conductor :)
Hydrogen like atoms are assumed to have just the one electron. This enables estimations to be made discounting the complex effects of other electons round the atom.
In the normal sense of "react", no parts meet: The nuclei remain distinct but electons may be shared.
There is one electron per hydrogen atom, and two atoms per molecule of hydrogen. So if you mean hydrogen gas, there are two electrons.
explain why electrial charges flow from one atom to another
Electron
Metals conduct electricity, because their atoms have a "sea" of "delocalised" electrons which pass on electrical energy from one atom to another.
When an atom is ionized, that means that it is sharing one or more electrons with another atom.
