_ more systematic than other periodic table at that time

Answer 2

Answer:

$\infty \infty Mendeleev's \: periodic \: table \infty \infty$

Explanation:

• Mendeleev periodic table based on chemical physical properties of elements and their atomic masses
• the periodic table contains eight vertical columns called groups and 7 horizontal rows called period
• examined the relationship between atomic masses of the element and chemical properties
• he sorted out the element with similar property and pinned the card together on the wall
• he observed that the most of the elements get place in the periodic table and were placed in order of their increasing atomic masses
• in his periodic table the properties of elements changed gradually in any period
• one of the strength of the Mendeleev periodic table was that when inert gas were discovered they could be placed in new group without disturbing the existing order
• he believed that some element will be discovered in future and name them by prefixing them a Sanskrit word Eka which means ban tune M of preceding element in the same group and he named this element as Eka Silicon Eka Boron Eka aluminium Eka magnesium etc .
