I need to write the lewis structures of two ionic compounds. Can anyone help me out? Thank you.
1) (NH4)2SO3
2) LiBH4

A Lewis structure is a diagram that represents the bonding and nonbonding electrons in a molecule. It is named after Gilbert N. Lewis, who first introduced the concept in 1916.
To draw a Lewis structure, you must first determine the total number of valence electrons in the molecule. Then, arrange the atoms in the molecule and connect them with single bonds. Finally, add lone pairs of electrons to fulfill the octet rule for each atom.
The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full outer shell with 8 electrons. This results in greater stability for the atom.
Yes, atoms in the third row of the periodic table and beyond can have expanded octets, meaning they can have more than 8 electrons in their outer shell. This is because these atoms have d orbitals available for bonding.
The central atom in a Lewis structure is typically the least electronegative atom. It can also be the atom with the lowest ionization energy or the most available valence electrons.
