jelperiodikus

Jelperiodikus, also known as the Periodic Table of Elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends, which provide insight into element behavior. The table contains 118 confirmed elements as of 2023. The first 94 elements exist naturally on Earth, and the remaining are synthetic elements. Each element is represented by a chemical symbol, which is usually derived from its name in English, Latin, or another language. The table is organized into periods (rows) and groups (columns). The periods are numbered from 1 to 7, and the groups are numbered from 1 to 18. The elements in the same group have similar chemical properties, while the elements in the same period have the same number of electron shells. The Periodic Table of Elements is a fundamental tool in chemistry, providing a way to predict the properties of elements and their compounds. It was first proposed by Dmitri Mendeleev in 1869, and it has since been expanded and refined to include all known elements. The table is widely used in education, research, and industry, and it continues to be an active area of study in the field of chemistry.
