Actually chlorine and hydrogen will not share electrons; the chlorine atom steals the electron from the hydrogen atom, creating two separate oppositely charged ions.
Hydrogen atoms share electrons in a covalent bond.
Hydrogen shares its electrons to complete the octate so it gains 1 electrons. it can also its electrons.
The covalent bonds that oxygen shares with hydrogen gives it a full outer shell of 8 electrons.
Eight. Oxygen has 6 electrons and shares two more with the hydrogen atoms in covalent bonds
Hydrogen atoms have one valence electron which is also the only electron they have.
IT gains, looses, or shares outer electrons.
In water molecules there are 2 atoms of hydrogen of and 1 atom of oxygen present. each hydrogen atom shares 1 electron with the oxygen atom. So the total number of electrons shared with oxygen are 2,total no. of electrons shared by hydrogen is 2 and the total no. of electrons shared by each hydrogen atom is 1.
