Step 1:I'll solve this chemistry problem step by step:
Step 2:: Understand Electronegativity Differences
Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond. The difference in electronegativity between two atoms determines the type of bond formed.
Step 3:: Recall Electronegativity Difference Ranges
- Ionic bond: $$\Delta\chi \geq 1.7
- Polar covalent bond: 0.5 \leq \Delta\chi < 1.7
Step 4:: Analyze the Electronegativity Difference Condition
The problem asks about bonds with an electronegativity difference greater than 1.7.
Step 5:: Identify the Correct Bond Type
Based on the electronegativity difference ranges, a bond with $$\Delta\chi \geq 1.7$$ is an ionic bond.
Final Answer
Explanation: When the electronegativity difference between two atoms is 1.7 or greater, the electrons are transferred almost completely from one atom to another, creating an ionic bond characterized by electrostatic attraction between oppositely charged ions.
