With increasing atomic number across a period, nuclear charge increases, pulling
 electrons closer and reducing atomic radii
As atomic number increases across the periodic table, nuclear charge (Z) increases and Z* increases. 
In turn, the atomic radius decreases because the higher nuclear charge (and thus higher Z*) pulls electrons closer to the nucleus. 
Atomic radius increases down the periodic table because the shell number increases.

The volume of the cubic tank is 2 × 2 × 2 = 8 cubic meters. The inlet has a circularcross-section with radius 3.5 cm, so the area of the inlet is 𝜋 × (0.035 ) 2 ≈ 0.00385square meters. With water flowing at 2 m/s, the volume flow rate is 0.00385 × 2 =0.0077 cubic meters per second. Therefore, the time to fill the tank is 8 /0.0077 ≈ 1039seconds, or roughly 17.3 minutes.
