Tiny particle that is the fundamental building block of all substances.
Particle found in the nucleus of an atom. Has positive charge.
Particle in the nucleus of an atom. Has no charge.
part of atom with a negative charge; orbits the nucleus.
Anything that takes up space and has mass.
Substance that contains only 1 kind of atom and cannot be broken down to simpler substances.
Atom that has a positive or negative charge.
Compound resulting from covalent bonding between atoms.
Bond between atoms where electrons are shared.
Bond formed by an attraction between partially charged atoms and a hydrogen that is covalently bonded to another partially charged atom.
Any compound that contains carbon bonded to at least one other atom, usually hydrogen.
Compound without carbon-hydrogen bonds
Electrons in an atom's outer layer. Electrons involved in bonding between atoms.
Polarity or Polar Molecule
Molecule which has positive and negative regions resulting from unequal sharing of electrons in a polar covalent bond.
Attraction of molecules between the same substance. ex: water molecule attracted to other water molecule
Attraction between molecules of different substances.
ex: water molecule attracted to molecules that make up spider web.
Substance that dissolves in a solvent.
Substance in which something is dissolved.
Mixture of where solute is dissolved in a solvent.
Versatile Solvent or Universal Solvent
Water can dissolve most substances making it a versatile solvent. This is due to its polarity which attracts anything with a charge.
Force that hold molecules together on the surface of a liquid.
The amount of heat per unit mass required to raise the temperature by
one degree Celsius.
Water has a high specific heat so it takes lots of energy to raise the temperature - due to hydrogen bonds in water.
Large molecules. Macromolecules found in all living things: Carbohydrates, Lipids, Proteins, and Nucleic Acids.
Macromolecules that are energy storage molecules. Contains carbon, oxygen, and hydrogen.
Macromolecules that are fats or oils (triglycerides), phospholipids, steroids, and waxes.
Macromolecules made up of amino acids. Makes up many parts of your body.
Macromolecules which are the genetic material - DNA and RNA.
