Solution Steps

Step 1: Understanding Electronegativity

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond. Generally, electronegativity increases across a period from left to right and decreases down a group in the periodic table.

Step 2: Analyzing the First Set of Elements (As, F, N)
  • Fluorine (F) is the most electronegative element in the periodic table.
  • Nitrogen (N) is also highly electronegative, but less so than fluorine.
  • Arsenic (As) is much less electronegative than both fluorine and nitrogen.
Step 3: Ordering the First Set of Elements

Based on the electronegativity values:

  • Fluorine (F) > Nitrogen (N) > Arsenic (As)
Step 4: Analyzing the Second Set of Elements (F, O, C)
  • Fluorine (F) is the most electronegative.
  • Oxygen (O) is the second most electronegative element after fluorine.
  • Carbon (C) is less electronegative than both fluorine and oxygen.
Step 5: Ordering the Second Set of Elements

Based on the electronegativity values:

  • Fluorine (F) > Oxygen (O) > Carbon (C)

Final Answer

  • For the first set of elements (As, F, N): \(\boxed{\text{F, N, As}}\)
  • For the second set of elements (F, O, C): \(\boxed{\text{F, O, C}}\)
