Question

Arrange the following ionsin order of their increasing ionic radii li+ , mg²+, k+, al³+

Answer 1

Answer:

Explanation:

Hii!

K+>Mg 2+ Al 3+> Li +

Try to find ionic raddi with help of z/e(z=atomic no,e=no of electrons)

Z/e ratio is inversely proportional to size

Now the values are 3/2,12/10,13/10/19/18 respectievely

Converting in decimale 1.5,1.2,1.3,1.14

If it is inversly prop then K+ has largest size followed by Mg 2+ Al 3+ and Li+

Hope it helps!
