Why was neon and helium missing from Newlands periodic table?
Neon and helium were missing from Newlands' periodic table because they are noble gases and were not well understood at the time. These gases are chemically inert and do not readily form compounds with other elements, making them distinct and not fitting into the periodic trends that Newlands was trying to establish.

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.
