Dmitri Mendeleyev — Дмитрий Менделеев

In 1869 the great Russian scientist Dmitri Mendeleyev announced the discovery of the Periodic Law of elements. So science received the key to the secrets of matter.
All the greatest discoveries which have been made since then in the fields of chemistry and physics have been based on this law.
The elements in Mendeleyevs Periodic Table follow one another in the order of their atomic weights. They are arranged in periods and groups.
Mendeleyev s discovery made it possible for the scientists to find 38 new chemical elements to fill the empty spaces left in the Periodic Table.
At the same time they tried to find elements heavier than the last element in the Periodic Table.
In 1955 the American scientist Dr. Glenn Seabord obtained element No 101 and named it Mendelevium in honour of the creator of the Periodic Law.

Дмитрий Менделеев

В 1869 г. великий российский ученый Дмитрий Менделеев

объявил об открытии Периодической таблицы элементов. Таким образом наука получила ключ к тайнам бытия.
Все самые большие открытия, которые были сделаны с тех пор в области химии и физики, были основаны на этом законе.
Элементы в Периодической таблице Менделеева следуют друг за другом в соответствии с их атомным весом. Они систематизированы в периоды и группы.
Открытие Менделеева позволило ученым обнаружить 38 новых химических элементов, заполнивших пустые места, оставленные в Периодический таблице.
В то же самое время они попытались найти элементы более тяжелые, чем последний элемент в Периодической таблице.
В 1955 г. американский ученый д-р Гленн Сиборд получил элемент номер 101 и назвал его Менделевиум в честь создателя Периодического Закона.
