1. Appointment of KIM for OGE- Evaluate the rіven of global lighting training in chemistry for graduates of the IX class of global lighting organizations with the method of sovereign attestation of graduates. The results of the test can be tested when you are admitted to a specialized class of a secondary school.
OGE is carried out according to the Federal Law Russian Federation dated December 29, 2012 No. 273-FZ “On education in the Russian Federation”.
2. Documents to be issued by KIM
3. Come to the selection of a replacement, a design of the KIM structure
The development of KIM for OGE in chemistry was carried out due to the improvement of the offensive positions.
- КІМ is oriented to re-verification of the acquired system of knowledge, as it is seen in the capacity of an invariant core of the same developing programs in chemistry for the main school. The Federal Component of the State Lighting Standard in Chemistry has a system of knowledge presented at a glance before the preparation of graduates.
- КІМ call to ensure the possibility of a differentiated assessment of the training of graduates. Therefore, the re-verification of the mastered basic elements of the chemistry course in the VIII-IX classes is based on three levels of folding: basic, advanced and high.
- The initial material, on the basis of which the students will be, is chosen as a sign of its importance for the education of graduates in the main school. For this reason, special respect is given to these elements of knowledge, as they will take their development in the course of chemistry X-XI classes.
4. Connection of the examination model OGE with KIM EDI
The most important principle that is insured during the development of KIM for the OGE, є їх decline from KІM ЄDI, is conditioned by the same approaches to the assessment of primary achievements in chemistry in basic and secondary schools.
The implementation of this principle is ensured: I could only, that they are presented to the choice of the council, that they are reviewed by the OGE tasks; similarity of the structures of the KIM exam options for OGE and EDDI; vikoristannyam analogous models zavdan, as well as the identity of systems for estimating zavdan similar types, as vikoristovuyutsya like in OGE, so in ЄДІ.
5. Characteristics of the structure of KIM 1
In 2017, the choice of bodies of higher authorities of the subjects of the Russian Federation, which controls the field of education, promotes two models of examination work, for its structure and change, include in it the task of similar models of examination work
The skin version of the examination work consists of two parts.
part 1 to avenge the 19th day with a short break, including the 15th day of the basic folding level (sequential numbers of these days: 1, 2, 3, 4, ... 15) and 4 days promoted equal folding (sequential numbers of the order: 16, 17, 18, 19). With all their authority, the heads of the divisions agree that the difference to the skin is recorded briefly in one digit or a sequence of digits (two or three). The sequence of digits is recorded in the form of identification without spaces and other additional characters.
part 2 in the fallow in the KIM model to take 3 or 4 heads of high level of folding, with a roaring wind. The retail of examination models 1 and 2 is folded in the morning and in the coming days until the end of the remaining examination tasks:
- exam model 1 to avenge task 22, which is passed on to the “obvious experiment”;
- exam model 2 to avenge the task on 22 and 23, which is passed on to a real chemical experiment.
The task of roztashovanі according to the principle of incremental growth of equal їх folding. A part of the dressing of the basic, advanced and high level of folding was folded in robots 68, 18 and 14% of the total.

2) characteristic reactions
3) do not separate from the water
4) avoid bromine water
5) enters into substitution reactions with chlorine

1) metal power is increasing and valency is increasing in water fields
2) the increasing charge of the nucleus of the atom and the radius of the atom
3) increasing number of electron balls in atoms and higher valency
