D425 Introduction to Chemistry Study Material
with Detailed Verified Solutions
Atom
the smallest unit of matter that retains the properties of that matter
Chemistry
the study of matter and its interactions
Elements
substances made up of a single type of atom
Mass
the measure of the amount of matter that an object contains
Matter
a substance that has mass and takes up space (volume)
Mixture
matter composed of two or more pure substances
Periodic Table
a chart that displays all the known elements according to the similarities between the
elements' properties
Pure Substance (substance)
has a constant composition (meaning that it is the same everywhere) and is made of a
single element or compound (ex: aluminum soda can)
Subatomic Particles
, the components of an atoms
Volume
the amount of space a substance or object occupies
How can matter be divided?
pure substances and mixtures
Chemical Bond
a force that holds two or more atoms together
Chemical Formula
a formula consisting of atomic symbols and subscripts to represent the number and
types of atoms within a molecule or a compound
Chemical Potential Energy
energy stores in atoms, molecules, and chemical bonds which make up matter
Chemical Property
describes the ability of a substance to undergo a specific chemical change and always
produce one or more types of matter that differ from the matter present before the
change
Composition
the arrangement of molecules and atoms
Compound
a substance made of two or more different elements chemically bonded; have uniform
and definite composition (ex: water)
