Answer»

Mendeleev told that the properties of element are periodic functions of their atomic masses!

Explanation:

1) He corrected atomic masses of some ELEMENTS like Be which was 14.9 to 9.01 !!

2) He predicted some elements which were later discovered like eka-boron, eka-aluminium and eka-silicon ; gallium, GERMANIUM and scandium !!

3) His table had spaces for noble gases!!

Problems;)))

1) Position for H2 was not SPECIFIED!!

2) Position for Isotopes!!

3) Atomic masses didn't increased with regular MANNER!!

Hope it won't help u ;-)
