How do you draw the Lewis dot structure for a molecule?

To draw the Lewis dot structure for a molecule, first determine the total number of valence electrons for all atoms in the molecule. Then, arrange the atoms in the molecule, placing the least electronegative atom in the center. Next, connect the atoms with single bonds and distribute the remaining electrons as lone pairs to satisfy the octet rule for each atom. Finally, check that each atom has a full valence shell and adjust the structure if needed.
