Question

the radius of a hydrogen atom is 5.3×10^-11 while the radius of the lead atom is 18×10^-11.compare the two and find relation between them.​

Answer 1

Answer:

The radius of the innermost orbit of a hydrogen atom, r1 = 5.3 × 10−11 m. Hence, the radii of an electron for n = 2 and n = 3 orbits are 2.12 × 10−10 m and 4.77 × 10−10 m respectively
