Question

What atomic number of an element x would have to become so that the 4th orbit around x would fit inside the 1bohr orbit of h atom?

Answer 1

Answer:

The atomic number is 16.

Explanation:

$r_n=\frac{n^2\times 52.9}{Z}$   (in pm)

where,

$r_n$ = radius of $n^{th}$ orbit

n = number of orbit

Z = atomic number

First orbit of hydrogen atom:

$r_{1,H}=\frac{1^2\times 52.9}{1}=52.9 pm$

Forth orbit of hydrogen like atom with atomic mass equal to Z:

$r_{4,x}=\frac{4^2\times 52.9}{Z}=52.9 pm$

$Z=16$

The atomic number is 16.

Answer 2

Answer:

16

Explanation:

Because of the Bhor's Model of Atom To Fix Inside The Fourth Orbit Around 'X'
