what type of molecule is hydrogen chloride gas
Chlorine and hydrogen are both non-metals. 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. By sharing the two electrons where the shells touch the hydrogen atom can count 2 electrons in its outer shell and the chlorine atom can count 8 electrons in its outer shell.
