Question

question 3 of 10
what is an ionic bond?

a. a bond formed from 2 atoms of the same element
b. a bond resulting from the transfer of 1 or more electrons
c. a bond between 2 atoms of similar electronegativities
d. a bond formed by sharing electrons

Explanation:

To determine the correct answer, we analyze each option:

• Option A: A bond formed from 2 atoms of the same element is a covalent bond (e.g., \( \text{O}_2 \)), not ionic. So A is incorrect.
• Option B: Ionic bonds are formed when one atom transfers one or more electrons to another atom, resulting in the formation of ions (e.g., \( \text{NaCl} \) where \( \text{Na} \) transfers an electron to \( \text{Cl} \)). This matches the definition of an ionic bond.
• Option C: A bond between 2 atoms of similar electronegativities is a covalent bond (since they share electrons rather than transfer them). So C is incorrect.
• Option D: A bond formed by sharing electrons is a covalent bond (e.g., \( \text{H}_2\text{O} \)). So D is incorrect.

Answer:

B. A bond resulting from the transfer of 1 or more electrons
