Read the text «PERIODIC LAW» [2].

One of the cornerstones of modern chemical theory is

The Periodic Law. It can be simply stated as follows: The properties of the elements are a periodic function of the nuclear charges of their atoms.

In 1869, Mendeleyev arrived at the conclusion that by the arrangement of the elements in order of increasing atomic weight the similarity and periodicity of properties of various, valence groups of the elements were clearly delineated.

There were several vacant spaces in Mendeleyev's table, which led him to predict the existence of six undiscovered elements, (scandium, gallium, germanium, polonium etc.). His confidence in the new classification was clearly expressed in the predictions, which he made of the chemical properties of these missing elements. And within fifteen years gallium, scandium and germanium were discovered.

Although this table has been modified hundreds of times, it has withstood the onslaught of all new facts. Isotopes, rare gases, atomic numbers, and electron configurations have only strengthened the idea of the periodicity of the properties of the elements.

Task-1. True or false?

1)Symbols and formulas are used to indicate chemical reactions.

2)Groups of symbols are called equations.

3)Groups of symbols are called formulas.

4)There are 102 chemical elements now.

5)The more electropositive element is always designated last in the formula.

6)Subscriptions are used to designate the number of atoms of each element present in the molecule.

7)Mendeleyev made his discovery in 1879.

8)There were several vacant spaces in Mendeleyev’s table which led him to predict the existence of six undiscovered elements.

9)The table wasn’t modified.

Task-2. Answer the questions.

1)How many chemical elements are there now?

2)What is the symbol of Manganese?

3)What is a symbol usually derived from?

4)What does a subscript show?

5)What element is always designated first in the formula?

6)When did Mendeleyev discover the periodic law?

7)How can the Periodic Law be simply stated?

8)What elements were discovered after Mendeleyev modified the table?

9)Give some examples of polyatomic molecules of single elements.

10) What are simple diatomic molecules of a single element designated by?

Active form of training "Rotating circle". Students become in two circles face-to-face; the students of the outer circle ask questions to the inner circle. The rotation of the inner circle in a clockwise direction and again the outer circle pose questions to the inner one, and so on until a complete rotation is realized. All students are lined up in a single line at 1, 2, 3.

End

5min

At the end of the lesson, learners reflect on their learning:

Learners have to write their answers on the stickers and stick it on a tree:

- What have you learnt today?

What would you like to learn?

What would you like to work on?

stickers and stick

Additional/ in formation

Differentiation – how do you plan to give more support? How do you plan to challenge the more able learners?

Assessment – how are you planning to check learners’ learning?

Healthandsafetycheck

Differentiation can be achieved through the selection of activities, identification of learning outcomes for a certain student, provision of individual support to learners, selection of learning materials and resources based on the individual abilities of leaners (Theory of Multiple Intelligences by Gardner).

Teacher assesses learners achievements with formative assessment by gests and by traffic lights

Health saving technologies.

Using physical exercises and active activities.

Rules from the Safety Rules book which can be applied in this lesson.

Reflection

Were the lesson objectives/learning objectives realistic?

Did all the learners achieve the lesson objectives/ learning objectives? If not, why?

Did my planned differentiation work well?

Did I stick to timings?

What changes did I make from my plan and why?
