Down a group, the atomic radius increases as the number of shells or energy levels increases.
the atomic radius increases down the periodic table as the number of shell (or energy level) increases.
Atomic Mass
it increases as you go down the periodic table
Electronegativity increases across (left to right) the periodic table and decreases on going down.
Down a group, the atomic radius increases as the number of shells or energy levels increases.
the atomic radius increases down the periodic table as the number of shell (or energy level) increases.
Yes, shielding increases as you move down a group in the periodic table.
Atomic Mass
The density properties generally change as you go down the columns of the Periodic Table by increasing.

Electronegativity increases as we move from left to right on the periodic table.
Periods (across the Periodic Table) have increasing Atomic Mass. Groups (down the table) have similar properties and reactive natures.
The number of valence electrons increases by one as you move down a group in the periodic table. Valence electrons are the electrons in the outermost energy level of an atom, and they determine the chemical properties of an element.
The melting temperature properties generally change as you go down the columns of the Periodic Table by decreasing for metals and increasing for non-metals.
The trend in solubility of alkaline earth metals increases as you move down the group on the periodic table.
