Question

(periodic table) Radii ___ top to bottom

Option 1: Increases
Option 2: Decreases
Option 3: Remains constant
Option 4: Varies unpredictably

Answer 1

The atomic radii increases top to bottom on the periodic table.

This correct answer is option 1.

Step-by-step explanation:

The atomic radii increases top to bottom on the periodic table.Option 1: Increases Option 2: Decreases Option 3: Remains constant Option 4: Varies unpredictably

Atomic radii trends show that as you move down a group or column on the periodic table, the atomic radii increase. This is because each successive element in a group has one more shell of electrons than the previous element, resulting in increased atomic size.

For example, in Group 1 of the periodic table, the atomic radius of lithium (Li) is smaller than that of sodium (Na), and sodium's atomic radius is smaller than that of potassium (K).

This correct answer is option 1.
