A chlorine atom has 7 electrons in its outer shell. Chlorine is in group 7 of the periodic table. A hydrogen atom has 1 electron in its outer shell. Hydrogen can only form 1 bond. The hydrogen atom will share its 1 electron with chlorine to form one covalent bond and make a hydrogen chloride molecule (HCl).This is a picture of a hydrogen chloride molecule. hydrogen atom has 1 electron in its outer shell. Hydrogen can only form 1 bond. The hydrogen atom will share its 1 electron with chlorine to form one covalent bond and make a hydrogen chloride molecule (HCl).
When two chlorine atoms come together to form a covalent bond, each atom contributes one electron to form a pair of electrons shared equally by the two atoms, as shown in the figure below. When a sodium atom combines with a chlorine atom to form an ionic bond, each atom still contributes one electron to form a pair of electrons, but this pair of electrons is not shared by the two atoms.
