Each row on the Periodic Table represents a new electron shell configuration. They get longer because each progressive shell has additional electron harmonic configurations available to them. In the nonmenclature of electron shell theory they are:
S 2
Sp 2 6
Sp 2 6
Spd 2 6 10
Spd 2 6 10
Spdf 2 6 10 15
Spdf 2 6 10 15
Electronegativity increases across (left to right) the periodic table and decreases on going down.
Sodium on the Periodic Table Is Na. No Go Sit Down And Learn The Periodic Table !:D
The number of shells in periodic table increase down the group, i.e., vertically.
left of the periodic table are the gases. as u go down the gases keep on becoming heavier
Far right, 3rd down.
In the left corner down of the periodic table.
Electronegativity increases across (left to right) the periodic table and decreases on going down.
The periodic table has 7 rows and 32 columns.
Elements are what make up the Periodic Table; they also cannot be broken down into smaller substances.
Periods (across the Periodic Table) have increasing Atomic Mass. Groups (down the table) have similar properties and reactive natures.

it goes up and down
The density properties generally change as you go down the columns of the Periodic Table by increasing.
the atomic radius increases down the periodic table as the number of shell (or energy level) increases.
The number of shells in periodic table increase down the group, i.e., vertically.
Down a group, the atomic radius increases as the number of shells or energy levels increases.
