What happens to electrons when an ionic bond is formed?
AThey are shared evenly between atoms
BThey leave the sample completely
CThey stay fixed on their own atom
DThey move from one atom to another
Answer & Solution
Correct answer: D. They move from one atom to another
1. Ionic bonding happens when the two atoms differ strongly in electronegativity.
2. One or more electrons are transferred from one atom to another.
3. The atom that loses electrons becomes a positive cation and the atom that gains them becomes a negative anion.
4. The two opposite ions are then held together by electrostatic attraction.
5. Sharing electrons evenly is covalent bonding, which is the other pattern entirely.
