The Correct Answer and Explanation is :
Here are the answers to the periodic table scavenger hunt, along with explanations for each element:
- Symbol Au
Answer: Gold
Explanation: The symbol “Au” comes from the Latin word “aurum,” meaning “gold.” It is a metal known for its beauty and rarity. - The most reactive nonmetal
Answer: Fluorine
Explanation: Fluorine is the most reactive nonmetal because it has a high electronegativity and readily forms bonds with almost all elements. - Monic number 12
Answer: Magnesium
Explanation: The element with atomic number 12 is magnesium (Mg). It is an alkaline earth metal used in a variety of applications, including the manufacture of lightweight alloys. - An alkali metal in period 4
Answer: Potassium
Explanation: Potassium (K) is an alkali metal located in period 4. Alkali metals are highly reactive and are found in Group 1 of the periodic table. - The most abundant element in air
Answer: Nitrogen
Explanation: Nitrogen (N) makes up about 78% of Earth’s atmosphere, making it the most abundant element in the air. - A metal with 3 valence electrons, used in cans
Answer: Aluminum
Explanation: Aluminum (Al) is a metal with 3 valence electrons and is commonly used in cans, foil, and other packaging materials due to its light weight and resistance to corrosion. - A period 3 element that will not react naturally
Answer: Argon
Explanation: Argon (Ar) is a noble gas in period 3. Noble gases are chemically inert and do not naturally form compounds. - Has 5 valence electrons and is in period 3
Answer: Phosphorus
Explanation: Phosphorus (P) has 5 valence electrons and is located in period 3. It is an essential element in biology and is found in fertilizers. - The most reactive metal
Answer: Francium
Explanation: Francium (Fr) is the most reactive metal. It is an alkali metal found in Group 1 and is highly radioactive. - A period 1 element used to make balloons float
Answer: Hydrogen
Explanation: Hydrogen (H) is the lightest element in period 1. It is used in filling balloons, though helium is more commonly used today for safety reasons. - The only nonmetal in group 14
Answer: Carbon
Explanation: Carbon (C) is the only nonmetal in Group 14. It is essential for life on Earth, as it is the basis of organic chemistry. - Responsible for the smell of rotten eggs, it has 16 protons
Answer: Sulfur
Explanation: Sulfur (S) is responsible for the foul smell of rotten eggs due to hydrogen sulfide (H₂S), which contains sulfur. It has 16 protons. - Has an atomic number that doubles silicon’s
Answer: Sulfur
Explanation: Silicon has an atomic number of 14, and sulfur has an atomic number of 32, which is double that of silicon. - The first element in the group of rare earth metals
Answer: Lanthanum
Explanation: Lanthanum (La) is the first element in the rare earth metals group. It is used in various technologies, such as catalysts and camera lenses. - A group 12 metal that was once used in thermometers but is now known to be poisonous
Answer: Mercury
Explanation: Mercury (Hg) is a group 12 metal once commonly used in thermometers but is now known to be toxic. - Has 3 valence electrons and 4 energy levels
Answer: Gallium
Explanation: Gallium (Ga) has 3 valence electrons and is in period 4. It is used in semiconductors and high-efficiency solar panels. - The only metalloid in period 3
Answer: Silicon
Explanation: Silicon (Si) is a metalloid in period 3. It is widely used in electronics and computer chips. - The only metalloid with 3 valence electrons
Answer: Boron
Explanation: Boron (B) is the only metalloid in Group 13 and has 3 valence electrons. It is used in materials such as glass and ceramics. - The alkali metal that makes up table salt
Answer: Sodium
Explanation: Sodium (Na) is an alkali metal that combines with chlorine (Cl) to form sodium chloride (NaCl), which is table salt. - Its most common isotope has 5 neutrons
Answer: Boron
Explanation: Boron (B) has an atomic number of 5, and its most common isotope, boron-10, has 5 neutrons.
