Bohr and the Periodic table

Bohr model atoms have three main parts: electrons, protons and neutrons. Each part costs a charge. It is positive, negative, or neutral. Electrons are always charged negatively. The proton is always negatively charged. Finally, neutrons are neutral or zero charged. If the charge of the whole atom is zero, it means there are the same number of positive and negative slices. Electrons are seen anywhere around the nucleus, and protons and neutrons are in the nucleus.

Based on the early (1882) T. Bayley model, J Tomsen designed a new watch in 1895. This is based on the electronic structure of the atom in 1922 by Niels Bohr. In this table (FIG. 2), since the length between inert gases has been lengthened for a while, the table shows two elements, two out of eight elements, two out of eighteen elements, and a period of 32 elements Included one of them and incomplete period. Elements of each period can be connected to one or more elements of the next period via connecting lines. The main disadvantage of this table is that the space required for the 32 element period is large and it is difficult to keep track of a series of very similar elements. A useful compromise is to list 14 elements, including 14 lanthanides (also called actinides) and 14 act elements (also called act elements), on a special two line under other periods . The cycle is compressed to 18 spaces.

Danish physicist Niels Bohr applied the quantum theory for the first time to the atomic structure and was moved by element placement in the periodic system. In the Bohr atomic model developed in 1916, electrons inhabit a series of concentric shells surrounding the nucleus. Mr. Boer believes that the outermost layers of the same element group in the periodic table can assume the same electron configuration. The chemical nature of the element largely depends on the arrangement of electrons in the atomic shell.
