Explanations: answer key for all 10 questions
- Q1: Who created the first widely recognized periodic table in 1869?
Answer: Dmitri Mendeleev
Mendeleev left gaps for elements that had not been discovered yet. He correctly predicted some of their properties.
- Q2: What gas is released when baking soda reacts with vinegar?
Answer: Carbon dioxide
The bubbles are carbon dioxide gas. The same gas helps cakes rise when baking soda is used in recipes.
- Q3: Rust forms when iron reacts with which two things?
Answer: Oxygen and water
Rust is iron oxide. Painting or coating iron keeps oxygen and water away from the metal.
- Q4: Which element gives fireworks a bright red color?
Answer: Strontium
Strontium salts glow red when heated. Copper gives blue and sodium gives yellow-orange, so chemists mix salts to create each color.
- Q5: Why are noble gases like helium and neon so unreactive?
Answer: Their outer electron shells are full
A full outer shell makes atoms stable. Neon glows red-orange in signs when electricity passes through it.
- Q6: A substance with a pH of 2 is what?
Answer: Strongly acidic
The pH scale runs from 0 to 14, and 7 is neutral. Lemon juice and stomach acid have low pH values.
- Q7: Which element has the chemical symbol Au?
Answer: Gold
The symbol comes from aurum, the Latin word for gold. Silver's symbol, Ag, comes from argentum.
- Q8: Why does salt melt ice on roads?
Answer: It lowers the freezing point of water
Dissolved salt makes it harder for water molecules to form ice. Below about minus 10 degrees Celsius, road salt works much less well.
- Q9: What is the most abundant element in the universe?
Answer: Hydrogen
Hydrogen makes up about three-quarters of normal matter in the universe. Stars fuse it into helium.
- Q10: Table salt is a compound of sodium and which other element?
Answer: Chlorine
Sodium is a reactive metal and chlorine is a poisonous gas. Together they form harmless sodium chloride.
Bing Chemistry Quiz – Elements, Reactions and Odd Facts
Chemistry is the science of matter and how it changes. It explains why cakes rise, why iron rusts and why fireworks burst into different colors. Everyday life is full of chemical reactions, even if we rarely notice them.
The periodic table organizes all known elements. Dmitri Mendeleev created the first widely recognized version in 1869 and even predicted elements that had not yet been found. Noble gases such as helium and neon sit on the far right and rarely react because their outer electron shells are full.
Kitchen and street chemistry are full of examples. Baking soda and vinegar release carbon dioxide, iron rusts when exposed to oxygen and water, and road salt melts ice by lowering water's freezing point. Strontium gives fireworks their red color.
Some facts surprise people. Hydrogen is the most abundant element in the universe, the symbol for gold comes from the Latin word aurum and table salt is made from a reactive metal and a poisonous gas. The pH scale shows how acidic or basic a substance is.
