Pure substance that can’t be separated into simpler substances by physical or chemical changes.
b)
Negatively charged particles found in the electron clouds of atoms.
c)
The number of protons in the nucleus of an atom that is equal to the atomic number
2.
Pure Substance
a)
A substance made up of only one kind of particle. (atom or compound)
b)
The smallest particle into which an element can be divided and still be the same substance.
3.
Atom
a)
The tiny, dense, positively charged center of an atom. Contains most of the atom’s mass and protons and neutrons are located there.
b)
The smallest particle into which an element can be divided and still be the same substance.
4.
Nucleus
a)
The tiny, dense, positively charged center of an atom. Contains most of the atom’s mass and protons and neutrons are located there.
b)
Positively charged particles found in the nucleus of an atom. Protons have a charge of +1.
5.
Proton
a)
Positively charged particles found in the nucleus of an atom. Protons have a charge of +1.
b)
Particles found in the nucleus of an atom that have no charge but have mass.
6.
Electron
a)
Negatively charged particles found in the electron clouds of atoms. Electrons have a charge of -1.
b)

7.
Neutron
a)
The Si or metric unit used to express the masses of particles in atoms.
b)
Particles found in the nucleus of an atom that have no charge but have mass.
8.
Atomic Mass Unit (AMU)
a)
The Si or metric unit used to express the masses of particles in atoms. Each proton and neutron has a mass of 1 amu.
b)
The number of protons in the nucleus of an atom is equal to the atomic number. Elements on the periodic table are arranged in order of atomic number.
9.
Atomic Number
a)
The number of protons in the nucleus of an atom is equal to the atomic number. Elements on the periodic table are arranged in order of atomic number.
b)
The sum of the protons and neutrons in an atom. Protons + Neutrons = Mass Number
10.
Periodic Table
a)
A table of the elements that organizes them according to a regular, repeating pattern.
b)
The properties of elements in a row follow a repeating pattern as you move across the period.
11.
Mass Number
a)
The sum of the protons and neutrons in an atom
