Periodensystem 2025 PRO 3.5.9

The Periodic Table is a mobile chemistry assistant designed for smartphones. It presents all chemical elements in an organized chart according to their atomic number, electronic configuration, and chemical properties.

The main components of the table include horizontal rows (periods) and vertical columns (groups or families). Each element is identified by a symbol and its atomic number. As one navigates from left to right and top to bottom, both atomic numbers and electron configurations vary, reflecting patterns in their chemical behavior.

This tool aids in understanding the properties of elements, their relationships, and trends. It is particularly useful for predicting reactions and exploring new materials, thereby facilitating the learning and application of chemistry.

The application allows users to easily answer various chemistry-related queries, such as: What is the atomic mass of samarium and polonium? What is the melting point of rubidium, and what are its RTEC and CAS numbers? In which year were bromine, gold, sulfur, and livermorium discovered, and who was responsible for their discovery? What are the physical appearances of bismuth, molybdenum, indium, or argon?
