Unit 1
These types of observations include the odor of a chemical reaction
What are direct observations
Particle motions in this state stay in place and vibrate
what is a solid
Atomic number of H
what is 1
the energy and particles that are emitted from unstable atoms
what is radiation
The maximum amount of solute that can dissolve in a particular solvent for a given temperature and pressure
what is solubility
The structure of DNA is this type of observation
What is indirect
Particle motion in this state are slow and slip past each other
what is liquid
Atomic number of He
what is 2
The process in which the unstable nuclei of atoms break down and emit radiation (as particles or energy) is known as this
Nuclear decay
Substances with chemical structures that have regions of partial charge are considered this
What is polar
This type of science deals with knowledge and discovery
What is pure science
particles motion in this state are very fast and collide with each other
what are gases
Atomic number of C
what is 6
Alpha radiation is a type of radiation produced when the unstable nuclei of radioactive elements emit these
what are alpha particles
the amount of a solute in a solution compared to the total amount of the solution
what is concentration
This type of science deals with knowledge use
What is applied science
The shape of this matter is generally fixed
what is a solid
An elements atomic number is based on this
What is the number of protons
These particles can penetrate paper, but they can be blocked by a sheet of metal like aluminum foil
What are Beta particles
a solution that has less of a solute dissolved than the maximum amount possible within a given amount of a particular solvent for a given temperature and pressure
what is an unsaturated solution
Most scientists follow a series of steps to acquire knowledge about the world called this
What is the scientific process
The particle arrangement of these particles are spacious and much farther apart than solids and liquids
what are gases
The atomic number of atoms is used to classify the elements on this table
What is the table of elements.
This type of radiation is produced when particles of light, called photons are emitted
What is Gamma
a solution that contains more than the maximum amount of a solute than can usually be dissolved within a given amount of a particular solvent for a given temperature and pressure
what is a supersaturated solution
