Periodic Table Database

This project contains a PostgreSQL database of chemical elements and a bash script to query element information.

Files

• element.sh - Bash script to query element information
• periodic_table.sql - Database dump file

Usage

Run the script with an atomic number, symbol, or element name:

./element.sh 1
./element.sh H
./element.sh Hydrogen

Database Structure

The database contains three tables:

• elements - atomic number, symbol, and name
• properties - atomic mass, melting point, boiling point, and type
• types - element types (metal, nonmetal, metalloid)

Examples

# Query by atomic number
./element.sh 1

# Query by symbol
./element.sh H

# Query by name
./element.sh Hydrogen
