Static Electricity Basics
Ever wondered why your hair stands up after going down a plastic slide? Static electricity happens when electrons build up in one place instead of flowing freely. Unlike normal electricity that moves through wires, static electricity stays put on surfaces.
Friction (like rubbing) is the main culprit behind static charge. When you rub two materials together, electrons get transferred from one to the other. The object that loses electrons becomes positively charged, whilst the one that gains electrons becomes negatively charged.
Here's the key rule: opposite charges attract each other, whilst like charges repel. This explains why charged objects can pull lightweight materials towards them or push similar charges away.
💡 Quick Tip: Lightning is just static electricity on a massive scale - clouds build up charge through friction, then discharge dramatically!

Atomic Structure and Models
Every atom contains three main particles that determine its properties. Protons have a positive charge and mass of 1, neutrons have no charge (0) but the same mass, and electrons have a negative charge with virtually no mass.
The nucleus sits at the atom's centre, containing protons and neutrons packed incredibly tightly. It's actually 10,000 times smaller than the whole atom! Electrons whizz around this tiny nucleus in the vast empty space that makes up most of an atom.
Scientists once thought atoms looked like a "plum pudding" - a cloud of positive charge with negative electrons dotted throughout like raisins in a pudding. This plum pudding model helped explain the discovery of electrons, though we now know atomic structure is more complex.
⚡ Remember: Atoms are mostly empty space - if an atom were the size of a football stadium, the nucleus would be like a marble in the centre!
