You look for if the molecule can have dipole moments based on the difference of electronegativity between the two atoms. Electronegativity increases across and up the table. However, beware that a molecule can be overall non polar but still have polar bonds. This is because, for example, in a CO2 molecule each C-O bond is polar. However, using vector addition, the two dipole moments cancel each other out thus making CO2 non polar.
