Atoms & elements

Grade 6 · Science · Free lesson

Welcome, explorer! Today, we are going to shrink down to super-microscopic size to discover the tiny building blocks of everything in the universe!

Imagine everything around you—your desk, your water bottle, and even your own body—is made of tiny, invisible building blocks. These microscopic blocks are called atoms, and they are the smallest units of matter!

An atom is made of even smaller parts! In the very center lies the nucleus, which holds positive protons. Buzzing around the outside like tiny planets are negative electrons.

+An Atom's StructureElectrons orbit the positive nucleus!

When you have a bunch of atoms that are all exactly the same type, you have an element! For example, pure gold is an element made only of gold atoms. Scientists group all these elements on a special chart called the Periodic Table.

AuGOLDAtom Number: 79An element contains only one kind of atom!
✏️ Worked example

If you have a ring made of pure silver, does it contain different types of atoms, or only one type?

  1. Identify the material: The ring is made of pure silver.
  2. Recall the definition of an element: An element is a pure substance made of only one specific kind of atom.
  3. Check if silver is an element: Yes, silver is a pure chemical element on the periodic table.
  4. Formulate the final answer: Since silver is an element, a pure silver ring contains only one single type of atom (silver atoms)!
