Periodic Table Structure

Description

Introduces students to the structure of the periodic table by showing the first three periods. Demonstrates how rows (periods) correspond to electron shells and columns (groups) indicate valence electrons, using Na and Cl as worked examples with Bohr-model shell diagrams.

Phases

#	Phase Name	Duration	Description
1	Title	~3s	Title appears
2	Mini Periodic Table	~6s	Simplified 3-period table fades in, rows and columns highlighted
3	Periods Explained	~5s	Highlight rows, label "Period = electron shells"
4	Groups Explained	~5s	Highlight columns, label "Group = valence electrons"
5	Na Atom	~8s	Highlight Na cell; draw Bohr model: 3 shells, 1 valence e⁻
6	Cl Atom	~8s	Highlight Cl cell; draw Bohr model: 3 shells, 7 valence e⁻
7	Outro	~3s	Summary text fades in

Assets & Dependencies

• Fonts: LaTeX / sans-serif
• Colors: Na = purple, Cl = green, period highlight = yellow, group highlight = cyan
• Manim version: ManimCE 0.19.1

Notes

• Table shows H, He (period 1), Li–Ne (period 2), Na–Ar (period 3)
• Bohr model uses concentric arcs with dot electrons
• Keep electron counts accurate (Na: 2,8,1 / Cl: 2,8,7)
