The Synthesis of "atomic number"

Discover what an atomic number is, why it's the unique identifier for every chemical element, and how it organizes the entire periodic table.

Discover the periodic table, the organized chart of all known elements that forms the building blocks of everything in the universe.

Learn what atomic mass means, how it's determined from an element's isotopes, and why this core concept of chemistry is so important.

Discover what atomic weight is, how it's calculated using isotopes, and why it's a fundamental concept in chemistry and the periodic table.

Discover what chemical elements are, why scientists are racing to create new ones, and how these fundamental building blocks of matter shape our world.

An explanation of isotopes, variants of elements that have widespread applications in medicine, industry, and scientific research.

Discover the proton, a key particle in the atomic nucleus that defines elements and is central to new frontiers in physics and medicine.

Discover valence electrons, the outermost atomic particles that dictate an element's chemical reactivity and its ability to form bonds with other atoms.

Discover the atomic nucleus, the tiny, dense core of an atom that holds the key to everything from nuclear energy to medical breakthroughs.

Understand electron configuration, the layout of electrons in an atom that defines an element's chemical behavior and properties.
