Question

increasing order of atomic size of group 1 elements?​

Answer 1

Answer:

As you go down Group 1: the number of occupied energy levels (or shells of electrons) increases from 2 to 6. the radius of an atom of the element increases from 134 pm to 225 pm.

Answer 2

Answer:

✍️✍️✍️✍️

Explanation:

I) Group 1 elements Li Na K Rb CsAtomic radius (pm) 152, 186, 231, 244, 262ii) The elements Li has the smallest atom (atomic radius 152 Pm) whereas the elements Cs has the largest atom (atomic radius 262 Pm).iii) From this arrangement, we find that the atomic size (or radius) increase down the group.
