Atomic radius are increase so density change by going down the periodice table
Density increases across a period as the size decreases and number of protons / neutrons increases.
Density decreases down a group as the size (or volume) of atom increases.
Generally the density of the chemical elements is increasing from the top to the bottom of the Periodic Table of Mendeleev.
Higher density
Electronegativity increases across (left to right) the periodic table and decreases on going down.
Going Up
The physical properties are not listed in periodic table. The properties like density is not listed.These can't be found on periodic table.
The statement applies to the horizontal rows or periods in the periodic table is that properties change going across each row.
it changes because you 50 years in 2013 it will change you will see
The density properties generally change as you go down the columns of the Periodic Table by increasing.

The melting temperature properties generally change as you go from left to right in the periodic table by going down/decreasing.
