Question

ratio of area covered by 4th orbital to 2nd orbital is​

Answer 1

Area of circle =πr

2

Hence,

Radius r of a shell ∝

z

n

2

Therefore,

Area ,A∝πn

4

(∵z=1 for both in this case)

For 1

st

orbit, n=1 and A∝n

4

or1

For 2

nd

orbit, n=2 and A∝16

Therefore ,

Areaof1

st

orbit

Areaof2

nd

orbit

∝

1

16

Hence the answer is 16:1

This is the right answer
