Cards

Term

 

 

Chemistry

Definition

 

the study of the properties of substances and how they react

with one another.

Term

 

 

substance

Definition

 

 

physical material from which

something is made.

Term

 

 

chemical reaction

Definition

 

 

rearrangement of atoms in a

substance to make a new

chemical substance.

Term

 

 

atom

Definition

 

the smallest particle of matter that cannot be broken down by chemical means.  An atom is made up of a nucleus of protons and neutrons, surrounded by a cloud of electrons.

Term

 

 

proton

Definition

 

a type of elementary particle that

 has a positive electrical charge and

is found in the nucleus of all atoms.

Term

 

 

neutron

Definition

 

a particle of an atom that has

no electrical charge and

is found in the nucleus of all atoms.

Term

 

 

electron

Definition

 

 

a stable, negatively charged particle found in all atoms.

Term

 

 

electrical charge

Definition
a fundamental property of matter.  Protons and the nuclei of atoms have a positive charge, electrons have a negative charge, and neutrons have no charge.  Normally, each atom has as many protons as electrons and thus has no net electrical charge.  In other words, the atom is neutral.
Term

 

 

nucleus

Definition

 

 

the central part of an atom, made up of protons and neutrons.

Term

 

 

nuclear reaction

Definition

 

a process in which two nuclei or nuclear particles collide to produce products different from the initial particles.
