Question

type the element in each list with the largest ionization energy: te, po, se sr, te, rb ga, br, f cl, ra, ba

Explanation:

Step1: Recall ionization - energy trend

Ionization energy increases across a period and decreases down a group in the periodic table.

Step2: Analyze Te, Po, Se

Se, Te, and Po are in Group 16. Se is above Te and Po. So Se has the largest ionization - energy among them.

Step3: Analyze Sr, Te, Rb

Sr, Te, and Rb are in the same period (Period 5). Te is to the right of Sr and Rb. So Te has the largest ionization - energy among them.

Step4: Analyze Ga, Br, F

F is in Period 2, Ga and Br are in Period 4. F is the most electronegative and has the largest ionization - energy among them.

Step5: Analyze Cl, Ra, Ba

Cl is in Period 3, Ba and Ra are in Period 6. Cl has the largest ionization - energy among them.

Answer:

Se
Te
F
Cl
