The beginning of the lesson 0-3 minutes 4-6 minutes 7-20 minutes 21-23 minutes	Ө Questions are asked about the previous lesson. Using the algorithm, students need to draw a diagram of the formation of a chemical bond formed from the atoms of these elements. To do this, students are given a schedule. Algorithm for the formation of ionic bonds in the first column of the table, consisting of 5 points: 1. The electron of the external energy level of the metal atom write the formula. 2. Determine the charge of an ion formed from a metal atom. 3. The electron of the external energy level of the nonmetal atom write the formula. 4. Determination of the charge of an ion formed from a non-metallic atom. 5. Write a diagram of the formation of ionic bonds, if necessary setting the coefficients. A) calcium and fluorin B) sodium and oxygen The task is for 10 minutes. Ask students why a solution of common salt conducts electricity, and why a solid salt does not conduct electricity. Why does distilled water not conduct electricity? And why does technical water conduct electricity? What do you think? What is a crystal lattice? Students search for themselves. Introduction of the idea of ​​"dots and crosses" diagram Dot-and-cross diagrams are used to show the electronic configurations of elements and ions. The electronic of one element in the compound are shown by dots, those of the second element by crosses.
