CHEMICAL REACTION AND ATOM COUNTING
- Velence electrons: number of electrons in the last energy level of an atom.
- Chemical Reaction: is the result of a chemical change.
- Reaction Indicators: You can also tell a chemical reaction has taken place by the formation of GAS.
- A chemical reaction can also release heat and light.
- The formation of a SOLID also indicates a chemical reaction.
- A chemical reaction can also be seen in rust, tarnishing, and carbonated drinks
- Molecule: Atoms that combine with other atoms to form larger units.
- Compound: Two elements chemically combine to form a new substance totally different from the elements that make up the compound.
- Chemical Reaction: is the result of a chemical change.
- A chemical reaction occurs when atoms separate, come together, or rearrange to form new substances with new properties.
- Reaction Indicators: You can also tell a chemical reaction has taken place by the formation of GAS.
- Carbon Dioxide, a gas, is oner of the products formed when baking soda and vinegar react.
- A chemical reaction can also release heat and light.
- The formation of a SOLID also indicates a chemical reaction.
- A chemical reaction can also be seen in rust, tarnishing, and carbonated drinks
- Molecule: Atoms that combine with other atoms to form larger units.
- Compound: Two elements chemically combine to form a new substance totally different from the elements that make up the compound.
