The discovery of the electron

Some reminders An element consist of one type of atom only. Therefore, elements are the simplest substances that we can use and investigate in chemistry because an element cannot be split into other substances unlike compounds. Each element has identical atoms except for isotopes, different numbers of neutrons - explained later which are physically and chemically identical and each element has its own unique physical and chemical properties.

Last Name Water Filters vs. Our Water Water filters are useless water passes through toxins!

Creating DDW as water passes through hot-cold zones fulfilling Biblical prophecy non-believers die from pestilence and disease!! This is a family business so we will be here to maintain the health of our customers even years from now!!

In weeks starting with some fuzz, I now have a full head of hair!! I was right and the inventor died at 62 after damaging his own heart: Now you have an opportunity to try the most patented distiller in America. Thirteen patents and approved FDA studies. What do these 13 patents do, and why are they needed?

The difference comes from what happens to the water being distilled.


They create energy while re-purifying the water hundreds of times per gallon using heat and UV light to destroy viruses and other pathogens that pose a threat to human health. Think of it as the Paul Bunyon of home distillers that does wonders both for home use and commercially.

The lagoon contained Click to Enlarge to read some of our ads and find out how John beat Cancer On June 3, the City of LaSalle reported that 24 hours after the lagoon was treated with 1, of John Ellis treated water, the odor was gone. What made that happen?

The electron is a subatomic particle, symbol e − or β −, whose electric charge is negative one elementary charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure.

J. J. Thomson - Wikipedia

The electron has a mass that is approximately 1/ that of the proton. However, people quickly realized that electric current was in fact made of moving electrons.

Since electricity is the lifeblood of everything from computers to phones to microwaves, the electron turned out to be interesting to just about everybody. An up-to-date periodic table with detailed but easy to understand information.

The discovery of the electron

An extension of our flagship DE-Series. Just as biological cryo-EM was revolutionized several years ago by direct detectors, low voltage EM, such as LEEM/PEEM, are on the cusp of a similar revolution.

The discovery of the electron disproved the part of Dalton's atomic theory that assumed atoms were indivisible. In order to account for the existence of the electrons, an entirely new atomic model was needed.
