Question

question 4 (0.166666667 points) cl has a greater ionization potential than br true false question 5 (0.166666667 points) k has a greater electronegativity than ca true false question 6 (0.166666666 points) la has more metallic properties than zr true false

Explanation:

• Question 4: Ionization potential decreases down a group. Chlorine (Cl) and bromine (Br) are in the same group (Group 17), and Cl is above Br. So, Cl has a greater ionization potential.
• Question 5: Electronegativity increases across a period from left - to - right. Potassium (K) and calcium (Ca) are in the same period (Period 4), and K is to the left of Ca. So, Ca has a greater electronegativity than K.
• Question 6: Metallic properties increase down a group and from right - to - left across a period. Lanthanum (La) is more metallic than zirconium (Zr) as La is more towards the left and bottom of the periodic table compared to Zr.

Answer:

Question 4: True
Question 5: False
Question 6: True
