Match each element with the description of it. The elements only include the first 20 elements and each element will only be described once. aluminum argon beryllium boron calcium carbon chlorine fluorine Element Name helium hydrogen lithium magnesium neon nitrogen oxygen phosphorus potassium silicon sodium sulfur Description of Element 1. A hard black solid. It helps make certain insecticides and detergents. It helps make some magnets. It is found in the material of bullet-proof jackets. It helps make Pyrex glass heat-resistant. It is used in MRI machines. 2. This is a colorless and odorless gas. It makes up 21% of the air and composes 65% of the human body. It is the most abundant element in the Earth’s crust. Three atoms of it combine to create a molecule of ozone. 3. This is a soft silvery-white metal. It is one of the elements that make up table salt. It is used in the manufacturing of hard soaps. It is very reactive with water and so is stored under mineral oil. It is found in a compound which is used in the expansion of air bags. 4. A lightweight metal. It is used to make mirrors for telescopes. It helps make emeralds. It is a structural material used to make high performance aircrafts, missiles and satellites. It is used to make windows for X-ray tubes. 5. Most fuels contain hydrogen and this element. Both graphite and diamonds are made from this element. All life on this Earth is ___ - based. 6. This element comes mainly in a red and white form. It is used to make safety matches. Organo-compounds with this element can be used as deadly nerve agents. It is an important component of DNA and the phospholipids of cell membranes. It is an important component of fertilizers. 7. This is a silvery metal that is reactive with water. It is important for a healthy nervous system. It is a component of potash which is a fertilizer. It is one of the elements in gunpowder. Match heads contain this element. 8. It is the lightest metal and very soft. It is used to treat manic depression. It can be found in some types of rechargeable batteries. It is used in alloys for aircrafts and missiles. You can find it in pacemaker batteries. 9. This is a colorless and odorless gas, but it glows blue-green and an electrical discharge tube. It is used as an atmospheric shield in arc welding. It is used as an asphyxiant in poultry farming. It is used in the processing of titanium. It is the third most common gas in the atmosphere. 10. It is a silvery metal that is flammable and reactive with water. It is a key component in fireworks. Since it is lightweight and has good electrical and mechanical properties, it is often used in portable electronics. 11. It is a silvery solid metalloid. It is a major component of glass, clay and quartz. It is the second most abundant element in the Earth’s crust. Since it is semi-conductive, it is used in the making of computer chips. It is a component in the making of breast implants. 12. This is one of the gases used in barcode laser scanners. It is an odorless, colorless and inert gas. It glows red in an electrical discharge tube. It helps make signs for night-time use. Plasma TV’s are filled with xenon and this gas. © Tangstar Science 3 aluminum argon beryllium boron Element Name calcium carbon chlorine fluorine helium hydrogen lithium magnesium neon nitrogen oxygen phosphorus potassium silicon sodium sulfur Description of Element 13.

It can be used as a fuel source. 14. It is a metal that can be recycled many times. It is a shiny silver-grey metal. It does not rust. “Tin foil” is actually made out of this element. It is lighter than steel. It is the third most abundant element in the Earth’s crust. 15. It is a yellowish gas. It was used as a respiratory irritant in WWII to induce choking. It can be safely consumed in small quantities in salt. It is used to make bleach. It is used to make PVC, which is the third most produced plastic in the world. 16. 78% of air is made out of this element. It is an important component of fertilizers, proteins and DNA. It is a colorless and odorless gas. It is used in SCUBA tanks for deep sea dives. 17. It is a colorless, odorless and inert gas. It is used as a coolant for nuclear reactors. It glows purple in an electrical discharge tube. It is used to fill party balloons and blimps. It is less dense than air. It is used in cryogenics for freezing. 18. This is a greyish silver metal. It is found in dairy products. It is essential from strong bones and teeth. It is a key component in chalk, cement, coral reefs and marine shells. 19. It is a yellow non-metal solid. It helps determine the texture of hair. It can be found in its elemental form in volcanoes and hot springs. It is found in compounds that are responsible for bad smells like rotten eggs and farts. It is responsible for some of the strong odors associated with garlic and onions. 20. It is the most reactive of all the elements. It is a yellow poisonous gas. It is found in Teflon non-stick coatings. It helps in the making of radioactive uranium. It is found in the chlorofluorocarbons (CFCs) that are destroying the ozone layer. FILL IN THE BLANKS 6. An element is a substance that contains all the same type of __________________. 7. A __________________ is a substance made up of two or more different types of atoms combined in _____________________________. 8. The elements are organized according to their __________________ on a chart called the ____________________________, which was first created by a Russian chemist and inventor named ____________________________ in the year ________. 9. The __________________ is a whole number in the element box of each element on the periodic table. This number gets __________________ (choose larger or smaller) as you go from left to right on the table. 10. The vertical columns on the Periodic Table are called __________________ and the elements in each one all share similar __________________. © Tangstar Science 4 Created by Anh-Thi Tang – Tangstar Science Copyright © 2013 Anh-Thi Tang (a.k.a.
