Question

calculate the radius of third bohr orbit of singly ionized atom helium.

Answer 1

actually
radius =(0.529) (n^2/z) A
where n is orbit number
z is atomic number
now
radius=(0.529)(9/2) A
=2.385A

Answer 2

Answer:

actually

radius =(0.529) (n^2/z) A

where n is orbit number

z is atomic number

now

radius=(0.529)(9/2) A

=2.385A
