Students learn how atoms bond to become stable — by transferring electrons (ionic bonds) or sharing them (covalent bonds) — and how these two kinds of bonds explain the properties of everything from table salt to water.
Students will be able to…
Why does sodium (a violent metal) plus chlorine (a poisonous gas) make harmless table salt? The secret is what happens to their electrons.
Project this and sort each feature into ionic or covalent bonding. Ask: are electrons transferred, or shared?
Tap any phase to open the teacher moves and student actions.
How do a violent metal + a toxic gas make safe salt?

Aligned to the Next Generation Science Standards (High School Chemistry) and Common Core literacy in science.
Use the periodic table to predict bonding and properties based on electrons.
Gather evidence about how particle-level structure affects properties.
Communicate why molecular structure is important in materials.
Determine the meaning of scientific terms and symbols.
