THE ATOMIC MODEL

• Student objective: Students will understand atoms better and know a atom's components.
• By: Jacob Malone

In this lesson their will be a QOD, facts, and a quiz all about atoms at the end of the slideshow

QOD

• What are the three particles in a atom and what are their charges?

ANSWERS

• Protons +
• Neutrons =
• Electrons --

ATOMS

• Atoms are the building block of all matter and make up everything we see.
• Atoms were first written in ancient Hindu writings more than 2600 years old.
• Democritus was a Greek atomistic that gave atoms their name from the Greek word atomos meaning invisible.
• He also concluded that atoms made everything.

The Further Development Of The Atomic Model

• Joseph Louis Proust in the 1790's made the Law of Definite Proportions.
• It established the masses of chemical substances formed into compounds.
• John Dalton was a English school teacher that decided the reason for this is the particles in atoms are in fixed ratios when combined.
• He imagined atoms as solid circles having a core and a heat envelope.

DIFFERENT ATOMIC MODELS

• Many other people added to or changed the model over the course of time.
• J.J Thomas said atoms could be divided and made the plum pudding model.
• Plums= negative while Pudding= positive.
• Ernest Rutherford found the nuclear atom and wrote about it.
• Neils Bohr found how to calculate the energy levels of electrons.
