Question

Each statement is true of Mendeleev's periodic table, the modern periodic table, or is true of both tables. Match both of the tables to each of their characteristics. Some characteristics may be used more than once.

Answer 1

The periodic table has evolved from Mendeleev's original design based on atomic mass to the modern table organized by atomic number, with both featuring a periodic repeating pattern in element properties.

Step-by-step explanation:

The periodic table, established by Dmitri Mendeleev in 1869, has evolved significantly over time to the modern periodic table we use today. While Mendeleev's periodic table was based on atomic mass, the modern periodic table is arranged by atomic number. Both tables have a repeating pattern in properties, which Mendeleev referred to as periodic, and they are organized into rows called periods and columns known as groups, where elements in the same group have similar properties. Mendeleev was able to predict the existence and properties of undiscovered elements, leaving gaps in his table, which later led to the validation and acceptance of his periodic system.
