Answer 2

In the modern periodic table, the elements are arranged in the order of their inreasing atomic number. In the modern periodic table there are seven horizontal rows called periods and eighteen vertical columns (1 to 18) called groups. The arrangement of the periods and groups results into formation of boxes .

Inner transition metals are in the f-block and have valence electrons in the f-orbital's. They consist of the Lanthanides and the Actinides.

Mendeleev classified the periodic table into horizontal rows and vertical columns. The horizontal rows are called as periods and vertical columns are called groups. Mendeleev's Periodic Table contains seven horizontal rows and nine vertical columns. The elements with similar properties come into the same group.

An English scientist called John Newlands put forward his Law of Octaves in 1864. He arranged all the elements known at the time into a table in order of relative atomic mass. ... He then put the similar elements into vertical columns, known as groups.
