Q: What is the effect of increasing the electronegativity difference between two bonded atoms?
Solution: An increasing electronegativity difference leads to greater ionic character in the bond, making it more polar.
Steps: 6
Step 1: Understand electronegativity. It is a measure of how strongly an atom attracts electrons in a bond.
Step 2: Identify the two atoms that are bonded together. Each atom has its own electronegativity value.
Step 3: Calculate the electronegativity difference by subtracting the smaller value from the larger value.
Step 4: Observe the electronegativity difference. If it is small, the bond is mostly covalent (sharing electrons).
Step 5: If the electronegativity difference increases, the bond starts to have more ionic character, meaning one atom pulls electrons away from the other more strongly.
Step 6: A larger electronegativity difference means the bond becomes more polar, which means there is a greater separation of charge within the bond.
