Understand the Problem
The question is related to the topic of the modern periodic table in chemistry. It seeks information or concepts regarding the arrangement, classification, and properties of elements in the modern periodic table.
Answer
The modern periodic table arranges elements by increasing atomic number and is based on the modern periodic law.
The modern periodic table classifies elements by increasing atomic number, arranged into periods and groups. It is based on the modern periodic law, which states that the properties of elements are periodic functions of their atomic numbers.
Answer for screen readers
The modern periodic table classifies elements by increasing atomic number, arranged into periods and groups. It is based on the modern periodic law, which states that the properties of elements are periodic functions of their atomic numbers.
More Information
The modern periodic table emphasizes the atomic number as a fundamental organizing principle rather than atomic mass, which was used in Mendeleev's early version. This reorganization corrected inconsistencies and led to a more accurate reflection of periodic properties.
Tips
Avoid confusing atomic number with atomic mass. The modern table uses atomic number for the fundamental arrangement.
