- 3. Comes from the German word kobold, meaning "goblin ore." How magical! It is magnetic and turns glass a deep blue. Its atomic number is 27
- 6. Roses are red, while violets are blue. Rubies are red, while this element with 24 electrons is black/gray/blue/violet/orange/green/yellow/purple/other colors/red too! In fact, rubies get their red color from small traces of this element!
- 8. the heaviest naturally occurring element is ______(U) with atomic number 92 and atomic weight 238.0289.
- 9. aurum is what I am called in Latin.I am yellow-ish in color.
- 10. used as laughing gas at the dentist, to distract your mind from a possibly painful dental procedure and help you relax!
- 11. Also called(Hg), this element dissolves and/or corrodes many metals, and as a result, it is not usually allowed aboard aircraft.
- 13. you may be surprised by this, but this element is mainly found in stars. It is the 5th most common element in the universe but comprises only 0.0018% of the Earth's atmosphere. Its atomic symbol is Ne.
- 14. The element that has the highest atomic number on the periodic table.
- 15. I am Iron but my atomic "nickname" is___
- 16. Although abundant on Earth, it is never naturally found in its pure form; it forms compounds with other elements. It is a component of salt and it is not chloride.
- 18. The element also known as (Cs) is a reactive element. It ignites spontaneously in air and reacts explosively with water. It is usually stored and shipped in mineral oil.
- 20. as an element, it is in crystal form. It is a metalloid and is known for being a poison.
- 21. (Mg), also known as______ is needed for more than 300 biochemical reactions in our bodies. (Mg) wheels – better known as mag wheels – were used in the 1960s. They were lightweight, making them ideal for racing. The downside was they were prone to corrosion and (incorrectly) thought to be flammable.
- 22. atoms are so light that they can escape Earth's gravity! This element is used in rocket propulsion (to pressurize fuel tanks, especially those for liquid. hydrogen, because only this element is still a gas at liquid-hydrogen temperature). It makes balloons float
- 23. (At) is the rarest naturally occurring element in the Earth’s crust.
- 24. There are only two liquid elements in the Periodic Table. ______(Hg) and Bromine (Br). They remain in liquid form at room temperature.

- 1. We associate neon (Ne) with bright signs. Neon is responsible for reddish-orange light, but another noble gas called ______ (Kr) may actually be responsible for multicoloured ‘neon’ signs. The tubes are painted with the desired colour, and krypton’s white discharge creates the glowing effect.
- 2. the lightest of all the metals and can easily float on water.It has one less electron that Beryllium.
- 4. Maybe this is your favorite superhero? Well, (Th) is named after Nordic god of thunder!
- 5. the most common element in the universe. It also has only one electron.
- 7. This highly explosive element is carbon's arch-nemesis. (Fl)______ is one of the few elements that can attack diamond.
- 9. did you know this element was named for Germany. It has an atomic number of 32
- 10. named after the Swedish chemist, engineer, inventor and businessman. He invented dynamite in 1867
- 12. Where do you think we can find (k)_____ in our food? Potatoes ? (Because it's called "this element's name")Correct! It can also be found in bananas, avocados, nuts, parsley, and chocolate. (Mmm...)
- 17. the water molecule has two of these.It is also the most abundant element in human body.
- 19. Like carbon's diamond, the element is almost invincible. What would you do if you saw a (mg)_____ fire? Spray nitrogen or carbon dioxide? Won't work! Pour water to put it out? That will only make it worse! (Mg) ______ fires are hard to put out, because they can burn through nitrogen carbon dioxide and water.
- 22. has an atomic number of 80.
