Alkali Metals
This element, the lightest and most abundant in the universe, is also a key component of water.
What is hydrogen?
This precious metal is known for its resistance to corrosion and is often used in jewelry and electronics due to its excellent conductivity.
What is gold?
This noble gas is commonly used in balloons because it is lighter than air and non flammable.
What is helium?
This halogen is a yellowish-green gas with a strong, suffocating odor and is used in many disinfectants.
What is chlorine?
This non-metal is essential for life and makes up a large portion of the air we breathe.
What is oxygen?
This element is slightly radioactive and found in bananas.
What is potassium?
This common metal is the primary component of steel and is essential for construction and manufacturing.
What is iron?
This noble gas is used in lighting because it glows a bright orange-red color when an electric current is passed through it.
What is neon?
This halogen is a dark purple solid that sublimes into a vapor with a strong, irritating odor. It's also essential in small amounts for human health, particularly for the thyroid gland.
What is iodine?
This non-metal is essential for plant growth and is a part of fertilizers. It's also found in many organic compounds, including proteins and DNA.
What is nitrogen?
This alkali metal is essential for nerve function and is commonly found in table salt.
What is sodium?
this lightweight metal is a good conductor of electricity and is often used in the aerospace industry.
What is aluminum?
This noble gas, making up about 1% of the Earth's atmosphere, is used in incandescent light bulbs to prevent the filament from oxidizing.
What is argon?
This halogen, the most reactive of all the elements, is so reactive it must be stored in special containers and reacts violently with almost everything, including water.
This non-metal is a key component of many organic compounds and exists in forms, including diamond and graphite.
What is carbon?
This alkali metal is the lightest of all metals and is so reactive it must be stored under oil to prevent it from reacting with the air.
What is lithium?
This metal, known for its toxicity, was historically used in paints and plumbing, but is now more commonly found in batteries.
What is lead?
This noble gas is used in some types of specialized lighting, including certain types of flash lamps and arc lamps, and is also used in some excimer lasers.
What is krypton?
This halogen is a reddish-brown liquid at room temperature and is highly corrosive. It has been historically used in photographic film.
What is bromine?
This non-metal is a yellow solid with a characteristic odor and is essential for the production of sulfuric acid.
What is sulfur?
This radioactive alkali metal, discovered by Marie Curie, is extremely rare and highly unstable.
What is francium?
This metal, vital for the production of stainless steel, is often used in alloys to increase strength and corrosion resistance.
What is chromium?
This noble gas, although relatively unreactive, has been shown to form compounds with highly electronegative elements like fluorine and oxygen under specific conditions.
What is xenon?
This radioactive halogen is the heaviest known halogen and is extremely unstable. Its chemistry is not well understood due to its extreme radioactivity and scarcity.
What is astatine?
This non-metal, essential for life, is a component of water and many other biological molecules. It exists as a gas at room temperature.
What is hydrogen?
