Answer:
The revised periodic table could account for variations resulting from isotopes.
Step-by-step explanation:
Dmitri Mendeleev was the first person to form the periodic table.
There are certain draw backs in Mendeleev's periodic table which need to be amended.
One such problem is that Mendeleev's periodic table lacks separate place for isotopes of an element. The isotopes share the same place in his periodic table. Hence, if a revised periodic table was formed in which there are separate places for the isotopes of an element then this problem can be amended.
