why hydrogen chloride forms covalent bond
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).
