Answer: <span>The main interactions between molecules of hydrogen chloride are examples of
Dipole-Dipole Interactions.
Explanation: The bond between Hydrogen and Chlorine is
Polar Covalent Bond as the
electronegativity difference between these two elements is
0.96 which is greater than 0.4. Chlorine being more electronegative attracts the electrons from Hydrogen making the Hydrogen
partial positive and itself
partial negative. The two poles on HCl makes it a dipole. Now, one HCl (a dipole) interacts with another HCl (another Dipole) through their opposite charges and creates
Dipole-Dipole Interaction. The picture is as below, the
green dashed lines are interactions,

Halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
I hope this helps you.
If you look at the periodic table you will see the atomic number (the smaller number) which is 3. that identifies how many protons there are. since the lithium is neutral that means there’s a same amount of electrons.
therefore there’s 3 electrons and 3 protons
