Sodium (Na) and potassium (K) are in the same group on the periodic table. Based on their locations, which statement about sodium and potassium is true?

• Sodium is less electronegative than potassium. 
• Sodium has fewer energy levels than potassium. 
• Sodium has a larger ionic radius than potassium. 
• Sodium has lower ionization energy than potassium. 

Which of these elements has the greatest atomic radius? 

• H
• N
• Cl
• Cs

The Periodic Table of the Elements is useful for revealing patterns and trends in the elements. Which statement accurately describes a pattern in the size of atomic radii in the Periodic Table of the Elements?

• Atomic radii decrease from left to right across a period and decrease from top to bottom in a group.
• Atomic radii increase from left to right across a period and increase from top to bottom in a group.
• Atomic radii decrease from left to right across a period and increase from top to bottom in a group.
• Atomic radii increase from left to right across a period and decrease from top to bottom in a group.
