Question

The ratio of areas within the electron orbits for the first excited state to the ground state for hydrogen atom is(a) 16 : 1(b) 18 : 1(c) 4 : 1(d) 2 : 1

Answer 1

don't know bhai.. ..

Answer 2

Answer:

The ratio of the area is 16:1.

Explanation:

We know that,

The square of radius of the orbit is directly proportional to power of four of the  number of state.

Where, n is the number of state

The area of the hydrogen for excited state

Here, n = 2 for excited state

The area of the hydrogen for ground state

Here, n = 1 for ground state

Now, the ratio of areas between the electron orbits for the first excited state to the ground state for the hydrogen atom is

Hence, The ratio of the area is 16:1.
