Sodium
Definition 1 of 2
Pro Tip 1/3
Safety Alert
Stress on sodium's reactivity and the need for careful handling in scientific contexts. Use goggles when demonstrating sodium's reaction with water.
Pro Tip 2/3
Not Ordinary Metal
Highlight that unlike most metals, sodium is soft and can be cut with a knife. Pure sodium is so soft you could cut it with a butter knife.
Pro Tip 3/3
Science Projects
Suggest its frequent use in school science experiments to demonstrate chemical reactions. For our project, we observed sodium reacting explosively with water.
