As per your syllabus, eqn 2.15, the radius of the n-th Bohr orbit for a hydrogen-like ion (one electron, atomic number Z) scales as which expression?
Ar_n is independent of Z
Br_n = 52.9 × (n² / Z) pm
Cr_n = 52.9 × Z² × n pm
Dr_n = 52.9 × n × Z pm
Answer & Solution
Correct answer: B. r_n = 52.9 × (n² / Z) pm
As per your syllabus, eqn 2.15, r_n = 52.9 n²/Z pm.
As Z increases, orbits contract; as n increases, orbits expand.
