Founder of the Atomism
-
- The laughing philosopher
- He thought that atoms are solid and their density is around the same size as their volume.
- atomic theory "Nothing exists except atoms and empty space. Everything else is opinion."
- The laughing philosopher
-
He revived the atomic theory.
-
Discovered oxygen
- in His writings of electricity he discovered many gases.
-
- He discovered that matter can not be created or destroyed.
- Defined the difference between the matter and a compound.
- He discovered that matter can not be created or destroyed.
-
- Came up with a mathematical formula for the charges between electrons. -- F is the force q1and q2 are the charges. And r is the distance between.
-
- Made his own law about definite proportions.
- All elements contained compounds
-
-The modern atomic theory "All atoms in a given element are exactly alike, while the atoms in different elements differ by atomic weight."
-
- He predicted that when they were accelerating, they were traveling in waves at the speed of light.
- These waves became known as electromagnetic waves.
- He predicted that when they were accelerating, they were traveling in waves at the speed of light.
-
- Discovered the Electron with its negative charge.
- Plum pudding model- the electrons were evenly disperse with the positive protons.
- Discovered the Electron with its negative charge.
-
- Introduced the quantum theory.
- E=hc/A -This explained the shape of the temperature vs. the color curve.
- Introduced the quantum theory.
-
- Discovered radioactivity
-
won the nobel prize for phisics
-
Introduced the first detection of individual alpha particles.
-
- Discovered and produced the first periodical table with elements.
-
- Atoms are made up of mostly space.
-They have a positive charged nucleus.- With negative electrons orbiting around it.
- Atoms are made up of mostly space.
-
Ernest Rutherford, Neils Bohr, and Werner Heisenberg came up with this theory.
-
- Won the nobel Prize for Chemistry.
- Worked more with radioactivity
-
- Developed the first successful model of an atom
-
- Discovered the atomic number
- Came up with the Moseley’s Law
-
-Measured the charge on electrons
- Photoelectric effect
-
- He claimed that every particle with a momentum has an equivalent wavelength. - (P=mv) wavelength of λ
-
-Discovered the neutron
-
-Proposed the Schrodingers cat thought experiment.
- This was about his problems with the quantum mechanics applied.
-
This was the last model created or discovered from the research i have found
