What kind of intermolecular forces act between a tetrachloroethylene molecule and a carbon dioxide molecule? Note: If there is more than one type of intermolecular force that acts, be sure to list them all, with a comma between the name of each force.

indium, and thallium have three electrons i think

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

it's filtration, but this is an assumption so my apologies if i got this

the answer is c. nacl
