Development of atomic theories
Storyboard Text
- well, I finally know that the atoms are the smallest unit of anything in the universe and cannot be divided further. I now also know that atoms cannot be created or destroyed. did you know that atoms of different elements have different masses.
- a few moths after spending days of experimenting.....
- HI! My name is John Dalton. I was wondering what atoms are ??? I want to learn about them.
- Ha! Guess what, atoms do have sub atomic particles. i just discovered a negatively charged particle, called an electron. I just found out that electrons are spread in the atom. my model kinda looks like a scoop of chocolate chip ice cream. lets call it the plum pudding model.
- Hello! my name is J.J Thompson. i was just reading about John Dalton's theory of atoms when i noticed something suspicious. I think that there should be some sub atomic particles in an atoms.
- hello again. remember what I told you...... there should be p+ charge in an atom as well. Here's what i discovered: a atom has a positive particle called proton the positive charge is clustered in the center of the atom in a bundle called the nucleus. the number of protons and electrons are the same in a atom.
- Hi, I am Earnest Rutherford. I reckon, if there is is a negative charge in an atom, there should be a positive charge as well to keep the atom in balance.
