?✔ Atomic symbol is given bcz of admire the specific atom in millions of atoms. Atomic symbol helps us to determine the atom.
Dmitri Mendeleev was a Russian chemist who lived from 1834 to 1907. He is considered to be the most important contributor to the development of the periodic table. His version of the periodic table organized elements into rows according to their atomic mass and into columns based on chemical and physical properties.
Silicon was discovered by Jöns Jacob Berzelius, a Swedish chemist, in 1824 by heating chips of potassium in a silica container and then carefully washing away the residual by-products. Silicon is the seventh most abundant element in the universe and the second most abundant element in the earth's crust.
The element silicon is used extensively as a semiconductor in solid-state devices in the computer and microelectronics industries. Sand (silicon dioxide or silica) and clay (aluminium silicate) are used to make concrete and cement. Sand is also the principal ingredient of glass, which has thousands of uses.
If elements had the same first letter, such as gold ( aurum ) and silver ( argentum ), Berzelius decided that the symbol would be the first two letters of the name: Thus, gold would be known as Au and silver as Ag.

Dalton's Law
Dalton's experiments on gases led to his discovery that the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the same space. In 1803 this scientific principle officially came to be known as Dalton's Law of Partial Pressures.In 1808, Berzelius discovered that lactic acid, previously discovered in milk, is also present in muscle tissue. Later he discovered lactic acid exists as two optical isomers.
He said that all the atoms of an element were tiny solid balls with the same mass and that the atoms of different elements differed in their atomic masses. He also said that atoms could join together to form compounds.
British chemist John Dalton was born in Eaglesfield, England, on September 6, 1766, to a Quaker family. He had two surviving siblings. Both he and his brother were born color-blind. Dalton's father earned a modest income as a handloom weaver.

The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.

Vital Force Theory. In what's called the vital force theory, it was believed that living organisms could create organic compounds from non-organic ones, and this was the only way for organic compounds to be created.
The Swedish chemist Jöns Jacob Berzelius (1779-1848) was one of the first European scientists to accept John Dalton's atomic theory and to recognize the need for a new system of chemical symbols. He was a dominant figure in chemical science.
In 1807, when he was appointed professor of medicine at the Stockholm School of Surgery, Berzelius began his researches in organic chemistry.
Thorium was discovered by Jöns Jacob Berzelius, a Swedish chemist, in 1828. He discovered it in a sample of a mineral that was given to him by the Reverend Has Morten Thrane Esmark, who suspected that it contained an unknown substance. Thorium oxide (ThO2), one of thorium's compounds, has many uses.
