How do you know if it's a polar molecule or a nonpolar molecule

And plz go easy I'm only taking biology and I am kinda slow!!

So decribe it thoroghly!!!

    Polar means the molecule has one side that's slightly positive and the other is slightly negative (ex water: the hydrogens are on an angle and because the oxygen pulls the electrons harder than the hydrogen, it becomes slightly negative (more electrons than protons) and the hydrogens are slightly positive.

    Generally polar molecules are only soluble in polar solvents and the same for non polar. This is why oil doesn't mix with water.

    Polar molecules are molecules that have different electron distribution.

    Thus, different parts of the molecules have different poles.

    Non-polar molecules are molecules that have the same electron distribution.

    Thus, every part of the molecules are equally charged.

    Non-polar molecules are usually diatoms or both atoms in the single molecule are the same. Polar molecules usually have two different atoms in the single molecule because different atoms have different charge distributions.

    a polar molecule has different partial charges around it and is hydrophilic (attracted to water). A non polar molecule is neutrally charged around it and is hydrophobic (does not mix with water)
