List of data references for chemical elements facts for kids

The List of data references for chemical elements is divided into datasheets that give values for many properties of the elements, together with various references. Each datasheet is sequenced by atomic number.

Imagine a giant library filled with information about every single building block of our universe! That's kind of what a list of data references for chemical elements is. It's a collection of special "datasheets" that hold important facts about each chemical element. These datasheets help scientists, students, and curious minds understand how elements behave and what they are used for. Each datasheet is neatly organized by its unique atomic number, making it easy to find any element you're looking for.

Chemical Element Datasheets

Chemical elements are the basic materials that make up everything around us. From the air we breathe to the ground we walk on, it's all made of elements. To understand how the world works, we need to know a lot about these elements. This is where chemical element datasheets come in handy.

What Are Chemical Elements?

A chemical element is a pure substance that cannot be broken down into simpler substances. Think of them as the fundamental LEGO bricks of the universe. There are over 100 known elements, and each one is unique. They are organized on the Periodic table, which is like a special chart that shows all the elements. Examples include oxygen, which we breathe, and gold, used in jewelry.

Why Do We Need Data About Elements?

Knowing the properties of elements is super important. Scientists use this information to create new materials, develop medicines, and understand natural processes. For example, knowing an element's melting point helps engineers choose the right metals for building bridges. Understanding how elements react helps chemists create new compounds. This data helps us solve problems and invent new things every day.

What Information Is on a Datasheet?

Each datasheet for a chemical element is packed with useful facts. Here are some of the key pieces of information you might find:

• Atomic Number: This is the most important number for an element. It tells you how many protons are in the nucleus of an atom of that element. Every element has a different atomic number.
• Atomic Mass: This number tells you how heavy an average atom of that element is.
• Melting Point: This is the temperature at which an element changes from a solid to a liquid. For example, iron melts at a very high temperature.
• Boiling Point: This is the temperature at which an element changes from a liquid to a gas. Water, which is a compound of hydrogen and oxygen, boils at 100 degrees Celsius.
• Density: This tells you how much "stuff" is packed into a certain space. Gold is very dense, meaning a small piece is quite heavy.
• State at Room Temperature: This tells you if the element is usually a solid, liquid, or gas when it's not too hot or too cold. Most elements are solids.
• Common Uses: This section explains how the element is used in real life. For instance, copper is used in electrical wires.

How Are Datasheets Organized?

The datasheets are organized in a very logical way: by their atomic number. This means that the element with atomic number 1 (hydrogen) comes first, then element 2 (helium), and so on. This order matches how elements are arranged on the Periodic Table. This makes it easy to find information quickly and to see patterns in how elements behave as their atomic number increases.
