Answer 2

There is no choice that is valid for the provided problem.

• The 18th organization of elements was not included in Mendeleev's fundamental periodic table because they were not believed at that duration and they are almost hidden because they won't react with any other element.
• Mendeleev acknowledged the traditional periodic law that “Element significance is a periodic procedure of their atomic weight.” Mendeleev placed elements in the mandate of their atomic weights in the characteristic of a table named Periodic Table of Mendeleev.
• Elements like gallium, Germanium and Scandium are evacuated by Mendeleev in his Periodic Table since its resolution.

Therefore, there is no choice correct for this problem.
