Create a comic on the reverse side of this sheet about the scientists and discoveries involved in the Modern
Theory of Atomic Structure. Use the information in Chapter 2 of your textbook.
BE CREATIVE AND HAVE FUN!!!
Your comic must have a title and must include all of the scientists below. For each of the required scientists,
incorporate their names, their important discoveries and/or ideas, and the approximate date or time-period of
• John Dalton
• Joseph John (J.J.)Thomson
• Ernest Rutherford
• Neils Bohr
• Erwin Shrodinger
These particles are surrounded by empty space and constantly moving at random!
Matter is composed of tiny indivisible particles.
They are all made up of small amounts of each of the four elements: Earth, Fire, Water, and Air.
all materials on Earth are NOT made of atoms!!
I discovered the atom! An atom is a uniform, solid sphere.
Here are my four postulates...
Dalton’s Four Postulates1. Elements are composed of small indivisible particles called atoms.2. Atoms of the same element are identical.Atoms of different elements are different.3. Atoms of different elements combine together in simple proportions to create a compound.4. In a chemical reaction, atoms are rearranged, but not changed.
My experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles- electrons!!
I discovered electrons!! Atoms are uniform spheres of positively charged matter in which electrons are embedded.
I postulated the nuclear structure of the atom, discovered alpha and beta rays, and proposed the laws of radioactive decay.
I received the Nobel Prize in Chemistry in 1908!!
An atom is a miniature solar system, with electrons orbiting around a massive nucleus, and as mostly empty space, with the nucleus occupying only a very small part of the atom.
Electrons should move around the nucleus but only in prescribed orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted.
I proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities.
