Question

Arrange the following elements in order of increasing atomic radius, from smallest to largest:

A) Fluorine (F), Oxygen (O), Nitrogen (N), Carbon (C)
B) Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F)
C) Oxygen (O), Nitrogen (N), Fluorine (F), Carbon (C)
D) Nitrogen (N), Oxygen (O), Carbon (C), Fluorine (F)

Answer 1

d) Nitrogen (N), Oxygen (O), Carbon (C), Fluorine (F).The elements should be arranged in order of increasing atomic radius:

Step-by-step explanation:

The elements should be arranged in order of increasing atomic radius. The correct answer is D) Nitrogen (N), Oxygen (O), Carbon (C), Fluorine (F).

• Nitrogen (N) has the smallest atomic radius because it is the smallest element among the given options.
• Oxygen (O) has a larger atomic radius than Nitrogen (N) because it has one more energy level and electrons are added at a greater distance from the nucleus.
• Carbon (C) has a larger atomic radius than Oxygen (O) because it is in the same period as Oxygen (O), but Carbon (C) has one less energy level.
• Fluorine (F) has the largest atomic radius among the given options because it is in the same period as Oxygen (O) and Carbon (C), but Fluorine (F) has one additional energy level.
