In the Periodic Table, the atomic size increases with every period due to addition of an extra shell.

The atomic size decreases with every group since no. of electrons and protons are increased with every group across a period leading to extra electrostatic force

of attraction between electrons and the nucleus and thus shrinking the size of the atom.

Who recognized a pattern in the properties of the elements and made the first periodic table?

In 1869, a Russian scientist named Dmitri Mendeleev arranged the elements in a table according to their atomic mass, this was the first periodic table. However, a few elements didn't fit the pattern in Mendeleev's table, so a new table had to be made, and that table is today's periodic table which is arranged by atomic number, and not atomic mass.
