he grouped the table into metals, non metals and gases.
Jons Jacob Berzelius discovered the elements selenium and thorium in 1817. He also played a significant role in developing the modern system of chemical symbols and atomic weights.
The modern system of naming substances based on their compositions was developed by the Swedish chemist Jöns Jacob Berzelius. Berzelius introduced the system of chemical symbols and atomic weights in the early 19th century, which laid the foundation for the modern system of chemical nomenclature.
Mendeleev's periodic system arranged elements based on increasing atomic mass and grouped them by similar chemical properties, revealing periodic trends. He predicted the existence and properties of undiscovered elements by leaving gaps in his table, demonstrating the periodic nature of elements. Additionally, Mendeleev's system highlighted the relationship between atomic structure and elemental behavior, laying the groundwork for the modern periodic table.
The periodic table of Mendeleev is a rational system of arrangement of chemical elements.

No, they are not elements in the modern, chemical sense. They were called elements in the ancient Greek philosophical system, which imagined everything to be made of them.
The concept of chemical symbols was introduced by the Swedish chemist Jöns Jacob Berzelius in the early 19th century. Berzelius is often credited with developing the modern system of writing chemical elements using one or two letters to represent each element.
False

Antoine Lavoisier, a French chemist, is often credited with introducing the modern idea of elements and compounds in the late 18th century. He is known for his work on the law of conservation of mass and for developing a system of naming chemical substances.

Antoine Lavoisier is known for his work on identifying and naming chemical elements, creating a system of chemical nomenclature, and developing the law of conservation of mass in chemical reactions. His contributions played a crucial role in the development of modern chemistry as a distinct scientific discipline.
They are supposed to have invented the banking system.
