What is the difference between the
mass number and the atomic mass??
300 Points
The mass number is Protons + Neutrons
The atomic mass is a weighted average of
all of the isotopes for that element

What is an isotope?
100 points

Isotopes are atoms that have the same
number of protons, but different number
of neutrons
100 points

What is the atomic number?
100 points

The atomic number is the number of
protons


What is Dalton’s theory?
400 points
All elements are composed of indivisible
particles called atoms
 Atoms of the same element are identical
 Atoms of different elements can
physically mix together of can
chemically combine with one another in
simple whole-number ratios
 Chemical reactions occur when atoms
are separated, joined, or rearranged.

What are the three rules for determining
the subatomic particles of an element?
(How do we calculate 1.protons, 2.
electrons, & 3. neutrons?)

200 points
The atomic number is equal to the
number of protons
 The number of protons is equal to the
number of electrons
 The number of neutrons is equal to the
mass number – the number of protons
