Answer 1

Holaaa Mate

Answer:

Chemistry is one of the most important branches of science which we practically apply in our daily lifestyle.

Also the chemical elements are also important in our daily lifestyle because most of the objects in our surrounding,are made out of these chemical elements.

And the periodic table was established to efficiently classify these chemical elements, to get a idea about the characteristics of these chemical elements.

That's why the periodic table is very important for ourselves.

Hope it helps..!!

Hello. buddy...

Explanation:

The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and non-metals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals.

Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals.The organization of the periodic table can be used to derive relationships between the various element properties, and also to predict chemical properties and behaviours of undiscovered or newly synthesized elements. Russian chemist Dmitri Mendeleev published the first recognizable periodic table in 1869, developed mainly to illustrate periodic trends of the then-known elements. He also predicted some properties of unidentified elements that were expected to fill gaps within the table. Most of his forecasts proved to be correct. Mendeleev's idea has been slowly expanded and refined with the discovery or synthesis of further new elements and the development of new theoretical models to explain chemical behaviour. The modern periodic table now provides a useful framework for analyzing chemical reactions, and continues to be widely used in chemistry, nuclear physics and other sciences.
