Unit 1
"a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses"
What is the scientific method?
The smallest component of an element
What is an atom?
A table filled with chemical elements and is organized by atomic number, number of electrons, and chemical properties
What is periodic table?
"a type of radiation produced when the unstable nuclei of radioactive elements emit alpha particles (helium nuclei)"
What is alpha radiation?
"a solution that contains the maximum amount of a solute that can be dissolved within a given amount of a particular solvent for a given temperature and pressure"
What is a saturated solution?
"A group of subjects or conditions that is matched as closely as possible with an experimental group, but is not exposed to any experimental treatment. The results are then compared to determine the changes that may occur due to the experimental treatment"
What is control group?
Anything that takes up mass and takes up space
What is matter?
Received credit of creating the periodic table but did not receive nobel prize
Who is Mendeleev?
"the energy and particles that are emitted from the nuclei of unstable atoms"
What is radiation?
"maximum amount of solute that can dissolve in a particular solvent for a given temperature and pressure"
What is solubility?
The prediction of what will occur in a scientific experiment
What is a hypothesis?
the state in which a substance has a definite volume but varies in shape
What is a liquid state?
"the bond of formed by the sharing of a pair of electrons by two atoms"
What is a covalent bond?
"the time it takes for half of the atoms in a radioactive element to decay"
What is a half life?
"solutions that have the concentration of their solutes expressed as a percentage"
What is percent solution?
