Question

instructions in each question, list the elements from least to greatest electronegativity:

1. indium (in), tellurium (te), antimony (sb)
2. polonium (po), oxygen (o), sulfur (s)
3. lithium (li), carbon (c), nitrogen (n)

Explanation:

Step1: Recall the trend of electronegativity

Electronegativity increases across a period from left to right and decreases down a group in the periodic table.

Step2: Analyze question 4

Indium (In) is in group 13, period 5. Antimony (Sb) is in group 15, period 5. Tellurium (Te) is in group 16, period 5. Since they are in the same period, as we move from left to right (In < Sb < Te), electronegativity increases.

Step3: Analyze question 5

Polonium (Po) is in group 16, period 6. Sulfur (S) is in group 16, period 3. Oxygen (O) is in group 16, period 2. As we move up a group (Po < S < O), electronegativity increases.

Step4: Analyze question 6

Lithium (Li) is in group 1, period 2. Carbon (C) is in group 14, period 2. Nitrogen (N) is in group 15, period 2. Since they are in the same period, as we move from left to right (Li < C < N), electronegativity increases.

Answer:

1. \(In < Sb < Te\)
2. \(Po < S < O\)
3. \(Li < C < N\)
