Hydrogen atoms have one valence electron which is also the only electron they have.
A water molecule is made up of two atoms of hydrogen and one atom of oxygen. Oxygen atom has six electrons in its outer most shell and a hydrogen atom has one electron in its outer most shell. Oxygen and hydrogen atoms are unstable because they have less than eight electrons in their outer most shells. Oxygen needs two electrons and hydrogen atom requires one electron tocomplete their valence shell. Oxygen atom combines with two hydrogen atoms by sharingelectrons. The bonds present between hydrogen atoms and oxygen atom are called single covalent bonds. In this way, oxygen and hydrogen atoms complete their outer most orbits. Oxygen shares two electrons with hydrogen atoms but its four electrons remain free in the water molecule. Therefore, there are two electron pairs or four electrons present in a water molecule.
One lone pair. The central atom is N (nitrogen) which has 5 valence electrons. Three of them are shared with 3 hydrogen atoms, leaving 2 electrons (1 lone pair) on the N.
There is 1 hydrogen atom and 1 chlorine atom in Hydrogen Chloride.
There is one lone pair of electrons in a molecule of ammonia: The single nitrogen atom in the molecule has five valence electrons; one of these is in a covalent bond with each of the three hydrogen atoms; and the remaining two valence electrons from the nitrogen atom constitute a lone pair.
A neutral barium atom has 56 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.
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

counting the shared electrons, 8.
There are 6 electrons in the outer most shell
Hydrogen shares its electrons to complete the octate so it gains 1 electrons. it can also its electrons.
Hydrogen is a metal element. There are 1 electrons in a single atom.
