Question: how many valence electrons does each atom have in hydrogen chloride (hcl)?
Answer: HCl (hydrogen chloride) H has 2 valence electrons as a result of sharing with Cl and the CL has 8 valence electrons as a result of sharing. Since there are only two atoms, the structure of a HCl molecule is linear. The electronegativity of H is 2.20 and the electronegativity of Cl is 3.16.
