In what manner is the long form of the periodic table better than Mendeleev's periodic table? Explain with examples.

Answers (1)

Modern Periodic Table is better than Mendeleev's periodic table because:

  • This table is based on the atomic number, which makes it more accurate.
  • There is a correlation between the position of the elements and their electron configurations clearly.
  • Complete separation of metals and non-metals has been achieved.
  • It eliminates the even and odd series of IV, V, VI and VII periods of Mendeleev's table.
  • Position of VIII Group is more appropriate than before.
