Chemistry Unit 6 - Particles with Internal Structure

Unit 6: Particles with Internal Structure

Instructional Goals

Describe the evidence that supports the idea that the simple particles have a property we call charge.
Describe the evidence that led Thomson to suggest that the mobile charge in atoms is negative.
Use the Thomson model of the atom to account for the fact that neutral atoms can become either positively or negatively charged by the loss or gain of electrons.
Describe the Rutherford gold foil experiment, what happened during the experiment, and how this changed the model of the atom.
List the properties that distinguish metals from non-metals.
Describe the evidence that distinguishes ionic from molecular or atomic solids.
Given the formula of an ionic or molecular substance, state its name.
Given the name of an ionic or molecular substance, write its formula.
From the name or formula of a substance, determine whether that substance is ionic or molecular.
