Chapter 2 Part 2 (Basic Chemistry) Flashcards
How are molecules formed?
When two or more atoms combine chemically
How is a compound formed?
When two or more different atoms bind together
How are electrons used in chemical reactions?
To make or break bonds
What is a chemical bond?
A bond where energy is holding atoms together
What is a ionic bond?
Bond formed by complete transfer of electrons from one atom to another.
What is a covalent bond?
Bond involving the sharing of electrons between atoms
What is a hydrogen bond?
A weak bond where hydrogen atom forms a bridge between two electron hungry atoms
Synthesis reactions occur when?
Two ore more atoms or molecules combine to form larger more simpler ones
Decomposition reactions occur when?
Complex substances are broken down into simpler ones
Exchange reactions occur when?
Bonds are both made and broken and atoms become combined with different atoms
What are inorganic compounds?
Compounds that lack carbon (water)
What is an organic compound?
Compound that contains carbon (Proteins, Carbohydrates, Fats)
