No chromium is more reactive than chromium because it it located farther right on the periodic table than nickel. No chromium is more reactive than nickel because it it located farther right on the periodic table than nickel. No chromium is more reactive than nickel because it it located farther right on the periodic table than nickel.

In 1869, Dmitri Mendeleev, a Russian chemist, presented the first Periodic Table.
No, to the right side
The atomic radius gets smaller the farther right it appears on the Periodic Table, until the addition of a new orbital increases the size again.
The question is badly phrased - I assume you mean "Who (not which) is considered the father of the periodic table" the answer a Russian named Dmitri Ivanovich Mendeleev
They are the vertical columns on the Periodic Table. Each column (top to bottom) is considered to be a group or family.
