It is difficult to study atoms because 2) What instruments do scientists use to study atoms? Scientists use _______________ and __________ to study atoms. 3) Draw your idea of what an atom looks like. Label any parts you can. 4) How do you think scientists see inside atoms? 5) List any facts you know about the atom. ____________________________________________________

differently if you repeated the lab? Would you use other materials? Di d y th ge ou e t rig m a ht ll ?
What does an atom look like? How did scientists figure out what it looks like? EQ: Why Do Theories Change Over Time? What Does an Atom Look Like? Questions Scientist Atomic Theory Picture
The atomic model has changed throughout the centuries, starting in 400 BC, when people thought it looked like a ball A model uses familiar ideas to explain unfamiliar facts observed in nature.
A model can be changed as new information is collected. Democritus Smallest piece of all matter is not divisible He named the smallest piece of matter atomos, meaning not to be cut. Atomos To Democritus, atoms
were small, hard particles that were all made of the same material but were different shapes and sizes. Atomic Theory John Dalton
1760-1844 Father of Modern Atomic Theory matter is made of atoms atoms in an element are identical different elements have different atoms atoms maintain their mass even in a chemical reaction J.J. Thomson 1897
When a magnet was placed near the beam of light, it separated into two parts When a magnet was placed near the beam of light, it separated into two parts Thomson Model This surprised Thomson, because the atoms of the
gas were uncharged. Where had the negative charges come from? Where did the negative charges come from? Thomson Model Proposed a model of the
atom that is sometimes called the Plum Pudding model. A small particle with negatively charged electrons scattered around. J.J. Thomson 1897 discovered electrons (charged particles)
