Algorithm for drawing up a diagram of the formation of molecules of a compound with a covalent polar

Algorithm for drawing up a diagram of the formation of molecules of a compound with a covalent polar bond (for example, H2S) 1) Determine the number of electrons at the external level (N) for nonmetal atoms and the number of unpaired electrons using the formula 8-N 2) Write down the electronic diagrams of nonmetal atoms (an element represented by one atom, write in the center) through the “+” sign so that the unpaired electrons are facing the adjacent sign. 3) Write down the electronic formula of the formed molecule, showing the shared electrons between the interacting atoms. 4) Write down the structural formula of the formed molecule, marking each common electron pair with a line. 5) Show the displacement of electron pairs to the atom (s) with a higher EO, ​​replacing the dashes with arrows and indicating the partial charges.

1) for the H atom – 1e, for the S atom – 2e, unpaired the same
2) H: S: H 2H * + * S
3) H: S: H
4) H-S-H
5) H-> S
