1. Atomic radius of Sodium atom = 186 x 10-12 m = 186 x 10-10 cm
Diameter of
sodium atom = 2 x Atomic radius = 2 x 186 x 10-10 cm
= 372 x 10-10 cm
Number of sodium atoms, arranged end to end, that
would have to be lined up to form a 1 cm line = 1 cm / 372 x 10-10 cm
= 1 x 1010 / 372 = 26,881,720.4 = 26,881,720
