If you mean the first 2 elements in the periodic table, they are the Hydrogen H and the Helium He. The periodic table is always read horizontally.

Just for more information, Hydrogen is used in rocket fuels and hydrogen bombs, and the Helium is commonly used for filling balloons (And yes that's the element that gives you a funny voice if you inhale it :p )

Hope this Helps! :)

The dominant intermolecular force that causes gaseous hcl molecules to attract one another is

AnnyKZ [126]

Answer:

Dipole-dipole attractions

Explanation:

The Cl atom is more electronegative than H, so it attracts the electrons in the H-Cl bond more to itself.

The Cl end of the molecule becomes partially negative (δ-), and the H end becomes more positive (δ+). This separation of charge is called an electric dipole,

When two HCl molecules are near each other, they arrange themselves so that the negative and positive ends of the dipoles line up and attract the two molecules together.
