Atomic structure

What you'll learn

1. 1

   Imagine a tiny blueberry muffin. The blueberry in the middle is the nucleus — it's super tiny but heavy! 🫐

2. 2

   What's in the very centre of an atom? 🎯

3. 3

   Here's a simple atom: a tiny nucleus (red) with electrons (blue) zipping around in circles. The nucleus has protons (positive) and neutrons (neutral).

4. 4

   Let's build a carbon atom together. Carbon has 6 protons, 6 neutrons, and 6 electrons. 🧪

5. 5

   For a lithium atom (3 protons, 4 neutrons, 3 electrons), how many particles are in the nucleus? 🧮

6. 6

   Build a helium atom! Drag the correct number of protons and neutrons into the nucleus, then add electrons around it. 🎯

7. 7

   Which part of the atom has a positive charge? ⚡
