1. What is the definition of atomic number?
Number of protons in the nucleus
2. What is the definition of atomic mass?
Neutrons + Protons; mass of an
atom

compare
and contrast
Mendeleev and Moseley’s
periodic tables.
explain the benefits and
drawbacks of the Bohr model of
the atom, and describe the
currently accepted theory of the
locations of electrons around an
atom.
By
1860, more than 60 elements
had been discovered
(How should we organize
all of these elements!?)
 Mendeleev
is
credited with
developing the
periodic table
(father of the PT!)
 Created
1869
his table in
 Mendeleev
arranged
the elements in order
of increasing atomic
mass and noticed
that certain similarities
in element’s properties
appeared at regular
intervals
Arranged
in
order of
increasing
atomic mass
Rows
and
columns
switched
 In
1911, Henry Moseley created a
periodic table that was arranged by
increasing atomic
number.
How is the PT organized today?
What is the main difference
between Mendeleev and
Moseley’s periodic table?
What are some similarities
between the two tables?
Natural States of the Elements
(solid/liquid/gas)
 explain
the benefits and drawbacks of
the Bohr model of the atom, and describe
the currently accepted theory of the
locations of electrons around an atom.

describe the
organization of the
electron cloud into
energy levels and
sublevels
 list
the amount of
electrons that can
fill each energy
level
What Bohr Did Right…
 Electrons
of increasing energy occupy orbits
farther and farther from the nucleus
 Electrons exist in quantized orbits (specific
energy levels).
 Electrons can’t exist between energy levels
Electrons can’t exist between energy levels, just like
people can’t stand between stair steps
With the partner who is sitting
next to you, create an analogy
about quantized energy
• Both partners need to contribute
to the final product
• Conversation should be on task
• 2 minute time limit!!

Answer: Clover
Name that orbital:
This orbital shape can hold

Why was Bohr’s model
wrong?
Why was Bohr’s model wrong?
Electrons do not orbit the
nucleus on singular paths
(like planets around the sun)
