Document Summary

Sodium consistency of hard butter - when has lost an e- strong chemical reactivity (catches fire when put in water) and makes lye and h2 (combusts) Ionic bonding connections that takes place b/n various elements ionic compound (salt) Salt when dissolved into fluid = electrolyte/ionic solution (ionizes when dissolved) to conduct electricity: when 2 electrodes if touch together should conduct electricity and lights up lightbulb. If put in water, then put in salt, can conduct electricity.
