The tavola periodica degli elementi represents a fundamental organization of chemical elements that showcases their periodicità chimica and relationships. This comprehensive system arranges elements based on atomic number and chemical properties, enabling scientists to predict element behaviors and characteristics.
• The modern periodic table contains 118 elements organized into 7 periods and 18 groups
• Elements exhibit periodic trends in properties like electronegativity and ionization energy
• Noble gases occupy the rightmost column and have extremely low reactivity
• Transition metals occupy the central block and show variable electron configurations
• The arrangement follows increasing atomic number and electron configuration patterns
