What Happens When We Excite Atoms and Molecules?
Excited atoms lead to exciting lessons! Learners use heat and light to excite both atoms and molecules. They display their learning in the form of Bohr models depicting the excited state of the atoms.

Electron Arrangement and Ion Formation
In this elements worksheet, students determine how electrons fill up the energy levels for the first 18 elements of the periodic table. Students determine if elements gain or lose electrons to form a stable ion. This worksheet has 4...

If My Configurations are Correct
Students write the electron configuration of elements in the ground state. In this chemistry lesson, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

Atomic Structure and Quantum Theory
Students are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory
