Question

question 8 of 25
which sentence describes the bond formed between two identical atoms?

a. the bond is very unstable because there is no electrostatic
attraction.

b. the electronegativity of the atoms determines the type of bond it
is.

c. one atom has donated an electron to another.

d. the electrons involved in the bond are shared equally between the
atoms.

Explanation:

• Option A: Bonds between atoms involve electrostatic attraction (e.g., between nuclei and shared electrons or between ions), so this is incorrect.
• Option B: For two identical atoms, electronegativity is the same, so it doesn't determine the bond type in this case (since electronegativity difference is zero), so this is incorrect.
• Option C: Donating an electron is characteristic of ionic bonds, and identical atoms don't form ionic bonds (as they have the same electronegativity and would not transfer electrons), so this is incorrect.
• Option D: When two identical atoms bond (e.g., in a diatomic molecule like \( \text{O}_2 \), \( \text{H}_2 \)), the electrons are shared equally because the atoms have the same electronegativity, leading to a non - polar covalent bond.

Answer:

D. The electrons involved in the bond are shared equally between the atoms.
