Question

If the radii of first orbits of H, He+, Li+2 And Be are r1, r2, r3, and r4, respectively. Then their correct decreasing order will be​

Answer 1

Answer:

The correct order will be

H>He  + >Li+2 >Be  3+

 

As the positive charge increases, the radius of ion decreases.

Answer 2

Answer:

H>He+>Li+2>Be+3

Step-by-step explanation:

r=0.529*n^2/z

where r= radius

n= orbit number

z= atomic number

using this formula we can calculate the radius and see that it decreases as atomic size increases
