(Polar molecules, Non-polar molecules, etc.)

If a molecule has one central atom with no lone pairs, four other atoms with two of them being the same, and the other two being the same (central atom + 2 A atoms + 2 B atoms, five atoms in total in this molecule.), would it still be a non-polar molecule? In other words, even though we have two different types of non-central atoms, would they still cancel each other in terms of partial charges?
It depends on the arrangement of the atoms, for example CH2Cl2 is polar.
It depends where the two atoms are placed. If they same atoms aren’t opposite of each other their dipole moments won’t cancel out thereby making it polar.
They would only be nonpolar if there was one central atom and all of the other atoms were the same element.
