T’was the week before Christmas, when Inspector Lestrade came to me with a most distraught
gentleman in tow. (Helium) ________ explained that the gentleman had purchased several pieces of
(Ag) ______and (Au) ________ jewelry for his wife (or mistress, (iodine) ___ surmised), which had
disappeared during a street (carbon + argon) __________ ride, ((nobelium) ________ doubt to see
(hydrogen+erbium) _______!) The victim interrupted with "You must (Fe) _______ this out before the

to (B) _________.

number (Sn) ______, an express which did not stop during (hydrogen + iodine+ sulfur) _________
trip. (Arsenic) ______ to unusual events, (helium) ______ remembered a (Cu) _______evicting the
occupants of the seat behind him and sitting there himself. Enjoying the ride, (helium) ___ was just
thinking, "These areas (As) _____," when a bad jolt made the ( calcium + selenium) _______ of
jewelry (sulfur + lithium + phosphorus) ______ between the seat and back of the bench (helium) ____
occupied. The (Cu) ___________ retrieved it for him. (Oxygen + nitrogen) ______ checking later, he
found the jewelry missing from the (calcium + selenium) ___________. (Astatine) ______ their
destination, (helium) ____ and the (Cu) ________ searched everyone, and each other, (arsenic)
____ well as the (carbon + argon) _______. (Nobellium) _____ jewels were found.
By this time, Lestrade seemed eager to (beryllium) _____ rid (oxygen + fluorine) ______ our
pompous victim, as (tungsten + arsenic) ____ (iodine) ____. (Indium) _____ private, the Inspector
explained that he wasn’t personally (Sb) ___________, but just wanted the theft cleared (uranium +
phosophorous) ______ quickly (sulfur + oxygen) _______ he could get (oxygen + nitrogen) ______ to
matters more important than petty theft. (Iodine) ___ agreed to help, not to save the Inspector time
and embarrassment (tungsten + helium + nitrogen) __________ he failed, (arsenic) ______ I
(potassium + neon + tungsten) ___________ he would, but I had the (calcium + selenium)
__________ already solved. Informed of this, the Inspector cried, "(Sulfur + oxygen) _____ fast!
(Hydrogen + oxygen + tungsten) _______?! My only reply (tungsten + arsenic) ____________ that he
meet me after (I) __________d, armed, and carrying a (Ni) ________.
(Astatine) __________ dusk, the Inspector and (iodine) ____ rode the next to last streetcar of
the day to the end (oxygen + fluorine) ______ the line, the (C) _____. I used Lestrade’s (Ni) ______
to pay my fare. (Indium) _____ the deserted (C) _______ I found number (Sn) ____ and climbed
inside. Reasoning that the culprit sat behind our victim (Pb) _______ me to examine that seat, and I
found scratches on the (F) ________. Prying (uranium + phosphorus) _______ a loose piece of (F)
________, I found the missing (Ag) ______ and (Au) ___________ jewelry in a (boron + silver)
______. I substituted worthless (SiO2) _____________ to simulate the theft of the (rhenium +
aluminum) ____________ articles, and replaced the (boron + silver) ______ under the (F)
__________. The Inspector and (iodine) ______ then concealed ourselves to await the thief. Nearly
dozing (oxygen +2 fluorine) ______, I was startled by the sound of footsteps echoing (indium) ___ the
deserted (C) ________. A shadow entered number (Sn) ______ and I heard the (F) _________ being
lifted, a brief silence, then an expletive and "The jewels (Ar) _____!" The Inspector yelled "Police!"
and I yelled "(Cs) ________!" as we both jumped into different ends of the streetcar. After a brief
struggle, the Inspector had his (Ne) _______ the culprit, (tungsten + holmium) ________ was
subdued and handcuffed. I turned (oxygen + nitrogen) ______ the torch and beheld a uniform
(oxygen + fluorine) ______ blue with (bromine + arsenic + sulfur) ________ buttons. "(Ho)

elementary, Inspector. He’s a (Si) __________ who found his comedy routine impersonating a (Cu)

2)
3)
4)
5)
The name of the new element
The element’s symbol
The atomic number
Where it is commonly found (be detailed!)
A colour picture of the element in either its natural or refined state
neutron
proton
6) Properties- there must be 8 properties listed to help describe the new element, including the following:
a)
b)
c)
d)
e)
Density
Colour
Hardness
Melting point
Boiling point
7) Uses- relate at least 3 uses to the different properties of the element in a 5-6 sentence description.
The Nobel board of directors will evaluate your findings in the following manner:
1) Content-
are all parts of the brief present?
/5
2) Writing-
is the writing well done?
/5
3) Creativity-
is there lots of imagination?
