04.04 Using the Periodic Table Assignment

Mission Briefing:You are an Intergalactic CSI that investigates crime scenes between galaxies!There has been a nuclear explosion on another planet.Your mission is to match the forensic evidence from the scene to our Earth’sPeriodic Table.Let’s make sure that you have all the atomic information that you will need!

Clue Review:

Part 1: Mission Preparation: Use the following word bank to complete the sentences accurately.

Part 2: Mission Activated: Your Mission is to use the knowledge you have obtained to correctlymatch the Galactic Element Clues (fake elements) to our Earth elements found in the Periodic Table below. Print and cut out each of the elements on the next two page. The blue elements are the Alien’s fake elements and the orange elements are Earth’s real elements. Use the clues on each of the Alien fake elements to match it to the real earth element. Once you have them matched, please type the alien’s elementsymbol (letter abbreviation) next to Earth’s element symbol in the periodic table below. The clue in red below has already been matched for you. Notice how Galactic Element (fake element) Gs has been written next to the real periodic element H in the periodic table. Use these examples to guide you on your mission!

METALS / METALLOIDS / NONMETALS

Directions: Print and cut out each of the following Alien elements and Earth elements. Use your knowledge of the atomic theory and periodic table to match one alien element to one earth element. Once complete take a photo of your work and submit to your instructor for credit. Be sure to include page 1 of this activity as well.

Fireworkium
Fw
This element has 15 protons and 15 electrons in its neutral atom. / Toothium
T
This is a nonmetal with an average atomic mass number close to 19. / Floatium
Fl
This is a gas that the aliens often use to fill balloons and blimps. It contains two protons in its nucleus. / Breathium
Bt
This element is a nonmetal and has one less proton than an atom of Toothium and has an atomic mass close to 16 amu. / Lightium
Lg
This is a gas that does not react with other elements. It glows when it is heated in a lamp or vacuum tube. It contains one more proton in its nucleus than Toothium.
Rottoneggium
Re
This is a nonmetal with one less electron than Mustarium. It has a total of 16 electrons in its nucleus. / Nobelium
Nb
This gas is located directly below Lightium on the periodic table and has an atomic mass close to 40 amu with 18 protons. / Liquidium
Lq
This nonmetal and has the second largest atomic mass number on the alien periodic table. / Supermanium
Sp
This element has the largest atomic mass unit on the alien’s periodic table at close to 84 amu. / Bonsium
Bo
This element is important for bone strength, both for aliens and earthlings. It is a metal in Group 2 of the periodic table and has 20 neutrons.
Organium
Or
This element makes up diamonds, which are not as valuable in other places in the universe as they are on Earth. It contains six protons in the nucleus of its atom. / Killum
Ki
This is a notoriously poisonous metalloid with an atomic mass close to 75 amu. / Universium
Uv
This is a heavy nonmetal, a pretty large atomic mass number and chemical properties similar to Rottoneggium and Breathium. / Semicoductium
Sc
This element is the metalloid with the lowest mass. It has one less proton than Organium. / Computerium
Co
This is an element that the aliens use in their electronics, stun guns, and in their communication devices because it is a semi-conductor. Significantly greater than the massof Semicoductium and has 14 electrons.
Ikium
Ik
This is a semi-conductor that is found below Computerium on the periodic table. The element has 32 protons and 41 neutrons. / Spriklium
Sk
An atom of this element may have an actual mass of70 amuwith 39 neutrons. / Alloyium
Am
This is a relatively rare metal that is often used as a hardening agent in metal alloys/mixtures. It is the second lightest metal on the periodic table. / Metium
Me
This is a very reactive metal with the lowest mass on the entire periodic table. / Bananium
Bn
This element has similar chemical properties to Softium and Metium, but is heavier than both.
Abundium
A
This is the ninth most abundant element in the universe. It is a metal with 12 protons in its nucleus.
