Why was Newlands and periodic table rejected?
Newlands' periodic table was rejected because it had gaps and did not account for newly discovered elements. The periodic table was improved by Mendeleev's table, which arranged elements in order of increasing atomic weight and left gaps for undiscovered elements. This allowed for a more accurate prediction of the properties of missing elements.
