Alien
Element
Clue
What did
you learn ?
Bo, Wo, J, L
They are
noble gases
Noble gases
are in group
18
Bo, Wo, J, L
Wo has
greatest
atomic mass,
Bo the least
The atomic mass of
the elements
increases as you
move left to right
and top to bottom
on the Per. Table
Alien
Element
X, By, Ch, Q
A, V, Kt
Clue
What did
you learn ?
Reactivity
They are the
decreases as
most reactive you move from
left to right on
group
the Per. Table
Non-metals
who typically
gain or share
one electron
-Atoms can gain or lose
electrons
-The # of electrons an
atom will gain, lose or
share is determined by
the group that it is in.
Alien
Element
E, Hi, T, Ss
T
Clue
What did
you learn ?
They are
metalloids
Metalloids are
located between
the metals and the
non-metals along
the zigzag line.
T has more
protons than
Hi
The number
of protons is
equal to the
atomic #
Alien
Element
Clue
What did
you learn ?
Pf, El
Pf is the
lightest
element, El is
the heaviest
The atomic mass
(lightness or
heaviness)
increases as you
move left to right
and down the
periodic table
Kt and By
Kt and By
make table
salt
Table salt is
made of NaCl
Alien
Element
Do
Fx
Clue
What did
you learn ?
Do has 4
protons
The number of
protons is equal
to the atomic
number on the
periodic table
Fx is
Carbon is
important in important in
the chemistry the chemistry
of life
of life
Alien
Element
R, Do
M, G, Ss
Clue
What did
you learn ?
R is less
reactive than
Do
The further to the
right you move on
the periodic table,
the less reactive the
element is
G has less
electrons
than M
As you move
across the periodic
table from left to
right, the number
of electrons
increases in each
period
Alien
Element
Up, Oz, Nu
Nu
Clue
What did
you learn ?
They all gain
2 electrons
Elements on the
right side of the
periodic table
gain electrons
(except for the
noble gases)
It’s a
diatomic
molecule
Diatomic = 2
atoms hanging
out together.
Oxygen hangs
our as O2
Alien
Element
An
Z, Pi
Clue
What did
you learn ?
An has 49
electrons
The number
of electrons =
the atomic
number
They lose 2
electrons
Atoms on the
left side of the
periodic table
tend to lose
electrons

Z is used in
flash bulbs
Mg is used in
flashbulbs
