Question

Organize the following elements in order of increasing atomic radius (Ge, He, Sr, O, Ba)

Answer 1

The order of increasing atomic radius for the elements Ge, He, Sr, O, Ba is: He, O, Ge, Sr, Ba.

Step-by-step explanation:

The atomic radius generally increases as we move down a group in the periodic table and decreases as we move across a period. To organize the given elements in order of increasing atomic radius (from smallest to largest), we first need to locate them on the periodic table. From the given elements (Ge, He, Sr, O, Ba), we can determine that the order of increasing atomic radius is:

1. He
2. O
3. Ge
4. Sr
5. Ba

Answer 2

He

O

Ge

Sr

Ba

Step-by-step explanation:

An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements.

In general, the size of an atom will decrease as you move from left to the right of a certain period.
