Question

❤HEY MATES PLZ ANS MY QUE❤✌

✌In group 1 of periodic table three elements X, Y and Z have atomic radii 133pm , 95pm

and 65pm respectively giving a reason, arrange them in the increasing order their atomic

number. ✌​

Answer 1

Explanation:

X- 133 pm

Y- 95pm

Z-65 pm

Now, as the atomic radii increase down a group, this means element at the bottom of the group will have largest atomic radius and vice-versa and atomic no. also increases,

therefore the correct order is Z,Y,X.

Answer 2

HEYA DEAR ❤️

The basic property of Periodic Table states that :-

The atomic radii of individual elements increase down the group because of their increasing number of electronic orbitals.

Applying to that logic ;

The increasing order of their atomic number will be :-

Z , Y, X

because the the atomic number increases while moving down the group.
