Choose and discuss 1 observed phenomenon from a lab (either melting point or electrical conductivity) that supports a characteristic of ionic bonding that we discussed in this section.
May choose:
- Sticky tape showing oppositely charged electrostatic forces attract
- High melting point showing generally stronger bond strengths
- Conducting electricity when dissolved in water due to dissociated ions
