Question

Explain the relationship between electronegativity and the tendency of an element to form an ionic bond.

A.RAMA NAGESWARARAO · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Electronegativity and Chemical Bonding
	**Related Topics**: Ionic Bonds, Covalent Bonds, Polarity
	**Prerequisites**: Definition of electronegativity, understanding of ionic and covalent bonding.
## SOLUTION PATHWAY
**Given Information**:
	We are analyzing the relationship between electronegativity and the tendency to form ionic bonds.
**Method & Steps**:
	1. **Electronegativity Definition**: Electronegativity is the tendency of an atom to attract electrons towards itself in a chemical bond.
		Reasoning: A higher electronegativity means a stronger pull on shared electrons.
	2. **Ionic Bond Formation**: Ionic bonds form when there is a large difference in electronegativity between two atoms.
		Working: The more electronegative atom essentially steals electrons from the less electronegative atom, resulting in the formation of ions (charged atoms) held together by electrostatic attraction.
		Key Point:  This transfer of electrons creates a strong electrostatic attraction, characteristic of ionic bonds.
	3. **Covalent Bond Formation**: Covalent bonds form when there is a small difference in electronegativity between two atoms.
		Result: The electrons are shared (more or less equally) between the atoms.
		Verification:  A large electronegativity difference leads to electron transfer (ionic bond), while a small difference leads to electron sharing (covalent bond). 
## OPTION ANALYSIS
[A] :x: A small difference in electronegativity favors covalent bonds, not ionic bonds.  Electrons are shared rather than transferred.
[B] :x: A large difference in electronegativity favors ionic bonds, not covalent bonds.  The large difference leads to electron transfer.
[C] :x: Electronegativity is the key factor determining the type of bond formed between atoms.  It dictates whether electrons are shared or transferred.
[D] ✓: This is the correct statement. A large electronegativity difference leads to the formation of ionic bonds due to the transfer of electrons from the less electronegative atom to the more electronegative atom.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing ionic and covalent bond formation with respect to electronegativity difference: Remember that a *large* difference leads to ionic bonds.
		2. Thinking electronegativity is solely about attracting any electron:  It specifically refers to attracting electrons *within a chemical bond*.
	**Quick Tips**:
		1. Think of electronegativity as 'electron greediness'. The more 'greedy' atom (higher electronegativity) will take electrons in an ionic bond.
		2. Visualize a tug-of-war: A large difference in strength (electronegativity) leads to one side completely winning (ionic bond), while a similar strength leads to sharing (covalent bond).

A.RAMA NAGESWARARAO · Answer

A small difference in electronegativity between two atoms favors the formation of an ionic bond.

A.RAMA NAGESWARARAO · Answer

A large difference in electronegativity between two atoms favors the formation of a covalent bond.

A.RAMA NAGESWARARAO · Answer

Electronegativity has no relationship to the type of bond formed.

A.RAMA NAGESWARARAO · Answer

The correct Option is "A large difference in electronegativity between two atoms favors the formation of an ionic bond."
