How to Look Up Element Properties with Claude
Look up periodic table element properties with Claude and ToolRouter. Atomic data, electronegativity, and physical properties.
Tool
Claude combines element property data with chemical reasoning — explaining why a particular electronegativity value matters for bonding, what an electron configuration tells you about reactivity, or why two elements with similar atomic numbers behave so differently. It connects the numbers to the chemistry.

Steps
Once connected (see setup above), use the Chemistry Lookup tool:
- Ask: "Get element properties for silicon using chemistry-lookup"
- Claude returns atomic number, weight, electron configuration, and physical properties
- Ask: "How do silicon's properties make it useful for semiconductors?"
- Request: "Compare silicon and germanium using chemistry-lookup"
Example Prompt
Try this with Claude using the Chemistry Lookup tool
Look up the properties of lithium, sodium, and potassium using chemistry-lookup. Compare their electronegativity, ionisation energies, and atomic radii, and explain the trend you see.
Tips
- Ask Claude to explain property trends across a period or group for deeper understanding
- Compare elements across a transition metal row to understand d-orbital effects
- Ask about industrial applications alongside raw properties for real-world context
