How do you determine the number of electrons that go into the Lewis structure of a molecule? A polyatomic ion?
Solution 25E Step 1 of 2 If we consider a molecule. After writing the correct Lewis structure, the number of electrons in the molecule can be obtained by summing the valence electrons of every single atom in the molecule. If we consider a poliatomic ion. The procedure it’s the same of above, but we have to consider the charge of the whole ion. The charge can be determined by adding an electron for each negative charge and subtracting an electron for each positive charge
