States that mass is neither created nor destroyed in any ordinary chemical reaction, or more simply, the mass of substances produced (products) by a chemical reaction is always equal to the mass of the reacting substances (reactants).
-
Says "These atoms are eternal and invisable." They are absolutely so small that they can't get any smaller.
-
Perceiving that in combustion and the calcination of metals only a portion of a given volume of common air was used up. Also known as "non-vital air".
-
Since he was color blind it as hard for him to see the colors that were coming out of his experiment. He suggested that a chemical combimation consists of a number of atoms definite and characteristc weights.
-
He created the original work covered a wide range, from questions in applied chemistry to the most general problems of chemical and physical theory.
-
Function basically describes a cloud-like region where the electron is likely to be found.
-
Invented the Plum Pudding method. In the cathode ray tube the particles that are being produced are negatively charged.
-
Designed by Ernesto Rutherford. He says that, "What was then the world's most sensitive electromagnetic wave detector."
-
He showed that radioactivity is a manifestation of sub-atomic change.
-
He measured the electric charges on tiny falling water (and later oil) droplets.
-
The components of the atoms have been discovered. Consists of a subatomic particles called protons and electrons.
-
Describing the atom as having a central positive nucleus surrounded by negative orbiting electrons.
-
His theory elaborated and expanded by other physicists, formed the basis for the developing science of quantum mechanics.
-
Which correlated wavelength and atomic number, thus demonstrating the importance of atomic number over atomic weight, as was the common belief.
-
Bohr's atomic diagram held that the outer orbits hold more electrons than the inner orbits.
-
He introduced the "Schrondinger's wave" a mathmatical equation of wave mathmatics.
-
He proved the existence of nuetrons and also a fundamental building block of the atoms nucleus.
-
Rationalised the various laws of chemical combination which were in existence at that time. However, he made a mistake in assuming that the simplest compound of two elements must be binary, formed from atoms of each element in a 1:1 ratio
-
Defines the electrons as moving along set orbits around the nucleus.
