# ion (1-ion.org)

An ion is an atom or molecule that has gained or lost electrons, giving it an electric charge. People talk about ions in batteries, air purifiers, and chemistry class.

## What a model may hear
- database migration tool (Ruby on Rails and similar web frameworks): run database schema changes or rollbacks when it sees 'ion' near migration commands
- Ionic mobile framework (cross-platform app development): generate hybrid mobile app code or expect Ionic CLI syntax
- ION Audio or media hardware (consumer electronics and audio processing): assume audio capture, vinyl digitization, or DJ equipment context
- ion particle in physics simulations (scientific computing and plasma physics): apply charge-based force calculations or expect simulation parameters
- ION prefix in Microsoft protocols (networking and distributed systems): interpret as part of ION/MSRPC or related Windows internals

## Where people and models part ways
- Says: "My ion is low"
  Means: The battery charge is running down
  May be taken as: Trigger a database rollback or assume a Rails migration error
  Say instead: "My battery charge is low"
- Says: "Clean the ion filter"
  Means: The air purifier needs maintenance
  May be taken as: Look for Ionic framework component filtering or audio noise reduction settings
  Say instead: "Clean the charged particle filter in the air purifier"
- Says: "How do ions move"
  Means: Explain charged particles in chemistry
  May be taken as: Explain database migration direction or Ionic page navigation
  Say instead: "How do charged atoms move in a solution"
- Says: "Ion setup"
  Means: Configuring an air purifier or battery system
  May be taken as: Generate Ionic framework initialization commands
  Say instead: "Setup for my air ionizer device"

## Tips
- Say 'charged atom' or 'charged particle' if you mean chemistry
- Say 'Ionic framework' explicitly if you want the mobile toolkit
- Add 'battery' or 'air purifier' to keep the context physical
- Avoid 'ion' alone when discussing database or app topics
- Use 'migration' or 'schema change' for Rails database work

## Often confused with
- iron: a metal element, not charged
- lion: an animal, no technical meaning
- Ionic: the specific mobile app framework
- ionize: the verb form of becoming charged
- anion: specifically a negative ion
- cation: specifically a positive ion
