(1) 1: 0.5 0.5 (2) 1:2:3
(3) 1:4:9
(4) 1: 8:27what is thecorrect answer
what is the correct answer ​

Answer 1

♦ The first three radius ratio of Bohr orbits is 1 : 4 : 9

→ Atomic number z is equal to 1.

Hence, the radius of nth orbit $r_{n}=0.529\:n^{2} A$

For first three orbits, n values are 1, 2 and 3

.°. Ratio of radii of first three orbit = $r_{1}:r_{2}:r_{3}=[n_{1}]^{2}:[n_{2}]^{2}:[n_{3}]^2 \\ \\</p><p>→ 1^{2}:2^{2}:3^{2}</p><p>→ 1:4:9$

Answer 2

Answer:

answer is option 3=1:4:9
