The electron-dot formula of the hydrogen chloride HCl is shown in the attached diagram below.
<h3>What is the lewis electron dot diagram?</h3>A lewis electron dot structure can be used to express the number of bonds, the bonding atoms, and the lone pairs remaining in the atoms in the molecule.
Lines are represented between atoms that are bonded with each other and excess electrons or lone pairs are shown as dot pairs and are placed next to the atoms.
As the valence electrons in the chlorine atom are equal to 7 from the electronic configuration of the chlorine atom. First, the total number of valence electrons in the HCl molecule is 7 + 1 = 8.
A chlorine atom requires only one electron to complete its octet configuration. As the octet completes, the rest of the electrons of Cl are assigned as the lone pairs of the Cl atom. Therefore, the chlorine atom has 3 lone pairs of electrons on it and the hydrogen atom completes its duplet.
