What is 241.67 amu?
You have discovered a new element and
have named it Neptunite. While studying
your new element, you find that it has three
isotopes—Neptunite–220, Neptunite–250,
and Neptunite-255. This is the average
atomic mass of your new element. (Assume
that these three isotopes are present in equal
amounts in nature.)

What are valence electrons?
Any element in group 15 would have 5
dots.
Lewis structures show the number of
_______ _______ in a particular element.
Show how many of these dots an element
in Group 15 would have.
$200
What are periods?
The name given to the horizontal rows on the
Periodic Table.

Who is Dimitri Mendeleev?
The name of the chemist who organized
the known 63 elements at the time by
increasing atomic weight and shared
properties into a Periodic Table. He did
this in 1869.
$600
What are groups or families?
The vertical columns on the Periodic Table are
called these and are arranged in a manner that
the elements in these columns have similar
chemical and physical properties.

What is Uranium (U)?
The element that is in Period 7 and is
considered radioactive because of its
large, unstable nucleus. It was one of the
fuels used to construct the early atomic
bombs in the WWII era.
$1000
What is Gold (Au)?
The name of the precious metal that
is in Group 11 and Period 6. It is
classified as a transition metal.
$200
What is form compounds?
The alkali metals, found in group 1 of the
periodic table are metals that do not occur freely
in nature. These metals have only one valence
electron in their outer shell. Therefore, they are
ready to lose that one electron in ionic bonding
with other elements very easily. This makes them
_______ _________ especially with group 17
because they have 7 valence electrons and when
the two combine they make the magic number
“8”.
$400
What are Alkaline Earth metals?
The ____________ elements are metallic
elements found in the second group of the
periodic table. They all contain 2 valence
electrons in their outermost energy level.
$600
The Boron family or group 13.
These elements have 3 valence electrons and are
called the _______ family.

also.

What is change over time as new things are
discovered?
The early work of Democritus (indivisible atoms),
Dalton (atoms are solid spheres), Thomson (Plum
pudding model), Rutherford (planetary model), and
Bohr (electrons are in shells around the nucleus) in
relation to the views on atomic theory have led us to the
current belief that electrons are found in clouds around
the nucleus (Electron Cloud Model). This shows an
example of how scientific theories can __________ when
new things are discovered.
