Is each compound best represented by an ionic or a covalent Lewis structure?
(d) K2 S
Here, we are going to identify whether the given compounds are best represented by an ionic or a covalent lewis structure.
The Lewis dot structure provide a picture of bonding in molecules and ions in terms of the shared pairs of electrons and the octet rule. While such a picture may not explain the bonding and behaviour of a molecule completely, it does help in understanding the formation and properties of a molecule to a large extent. Writing of Lewis dot structures of molecules is, therefore, very useful.
