Answer 1

Heya user ! ️✋

✍Here's the required answer :

☀Mendleev periodic table :

⚪Elements in this periodic table were arranged in order of their relative atomic mass.

⚪He arranged the table so that groups of elements with similar properties fell into vertical columns in his table.

⚪Sometimes between the rows in his table , there were some gaps , which mandeleev thought that those gaps are of the elements which are not yet discovered.

⚪He predicted some elements seeing the gaps and properties, which later on turned out to be right.
