71 electron Ex. 19. Assuming a spherical shape for the F nucleus, calculate the radius and the nuclear density of the F nucleus of mass number 19. ntimetres Solution: We have, nd orbit r= (1-4 x 10-13 )A3 p from 1-4 x 10-1x 193 = 5-07 x 10 cm. (Eqn. 8) 4 Volume of 1 F atom =u x3-14 x (5-07 x 10-133 = 7-17 x 10- cm mass of 1 mole of nucleus Mass of a single nucleus = Av. n0. 19 6-022 x 10 238 Thus, density of the nucleus = mass of single nucleus volume of single nucleus
