(b) Nagaoka proposed that atoms resembled the planet Saturn, with a ring of electrons surrounding a positive “planet.” (credit a: modification of work by “Man vyi”/Wikimedia Commons credit b: modification of work by “NASA”/Wikimedia Commons) (a) Thomson suggested that atoms resembled plum pudding, an English dessert consisting of moist cake with embedded raisins (“plums”). A competing model had been proposed in 1903 by Hantaro Nagaoka, who postulated a Saturn-like atom, consisting of a positively charged sphere surrounded by a halo of electrons ( ). ![]() In 1904, Thomson proposed the “plum pudding” model of atoms, which described a positively charged mass with an equal amount of negative charge in the form of electrons embedded in it, since all atoms are electrically neutral. However, the positively charged part of an atom was not yet well understood. Scientists had now established that the atom was not indivisible as Dalton had believed, and due to the work of Thomson, Millikan, and others, the charge and mass of the negative, subatomic particles-the electrons-were known. The term “electron” was coined in 1891 by Irish physicist George Stoney, from “ electric i on.” Although controversial at the time, Thomson’s idea was gradually accepted, and his cathode ray particle is what we now call an electron, a negatively charged, subatomic particle with a mass more than one thousand-times less that of an atom. (credit a: modification of work by Nobel Foundation credit b: modification of work by Eugen Nesper credit c: modification of work by “Kurzon”/Wikimedia Commons)īased on his observations, here is what Thomson proposed and why: The particles are attracted by positive (+) charges and repelled by negative (−) charges, so they must be negatively charged (like charges repel and unlike charges attract) they are less massive than atoms and indistinguishable, regardless of the source material, so they must be fundamental, subatomic constituents of all atoms. Simultaneous deflections by applied electric and magnetic fields permitted Thomson to calculate the mass-to-charge ratio of the particles composing the cathode ray. (c) In the cathode ray, the beam (shown in yellow) comes from the cathode and is accelerated past the anode toward a fluorescent scale at the end of the tube. (b) This is an early cathode ray tube, invented in 1897 by Ferdinand Braun. Thomson produced a visible beam in a cathode ray tube. The results of these measurements indicated that these particles were much lighter than atoms ( ). ![]() In similar experiments, the ray was simultaneously deflected by an applied magnetic field, and measurements of the extent of deflection and the magnetic field strength allowed Thomson to calculate the charge-to-mass ratio of the cathode ray particles. This beam was deflected toward the positive charge and away from the negative charge, and was produced in the same way with identical properties when different metals were used for the electrodes. When high voltage was applied across the electrodes, a visible beam called a cathode ray appeared between them. ![]() This apparatus consisted of a sealed glass tube from which almost all the air had been removed the tube contained two metal electrodes. If matter were composed of atoms, what were atoms composed of? Were they the smallest particles, or was there something smaller? In the late 1800s, a number of scientists interested in questions like these investigated the electrical discharges that could be produced in low-pressure gases, with the most significant discovery made by English physicist J.

![]() Sorry if my backstory is unoriginal or bad. The lady kind of regrets sending her there but she kept reminding herself that she'll learn soon enough. Now Nineteen is trying to find a way back to her mother by escaping the lower levels. The lady,not understanding that Nineteen doesn't understand what her intentions are for, sent her to the lower levels of the jaw, as apunishment but also to teach her to just accept her intentions and finally understanding it. A few more years past and Nineteen finally had the courage to tell the lady that her intentions are bad and she needs to stop them. A few years past and the lady was now the mother of Nineteen, she told her the plans and intentions of hers about the maw and what she'll do to keep it alive, nineteen however didn't like it and was still pretty young at the time so she didn't get the lady's intentions much. 7 years ago they fought and went their seperate ways, hatred and anger in their hearts.

If you're unsure whether your reason is legitimate, consult your lawyers. You should not scrape personal data unless you have a legitimate reason to do so. However, you should be aware that your results could contain personal data. They only extract what the user has chosen to share publicly. Our Facebook scrapers are ethical and do not extract any private user data. Is it legal to scrape Facebook Pages data? To access the API using Python, use the apify-client PyPI package.Ĭheck out the Apify API reference docs for full details or click on the API tab for code examples. To access the API using Node.js, use the apify-client NPM package. The API also lets you access any datasets, monitor actor performance, fetch results, create and update versions, and more. The API is organized around RESTful HTTP endpoints that enable you to manage, schedule, and run Apify actors. The Apify API gives you programmatic access to the Apify platform. Using Facebook Pages Scraper with the Apify API You can also use webhooks to carry out an action whenever an event occurs, e.g., get a notification whenever Facebook Pages Scraper successfully finishes a run. You can integrate with Make, Zapier, Slack, Airbyte, GitHub, Google Sheets, Asana, Google Drive, and more. Last but not least, Facebook Pages Scraper can be connected with almost any cloud service or web app thanks to integrations on the Apify platform. Or let us know if you need a custom scraping solution. You can keep the scraper to yourself or make it public by adding it to Apify Store (and find users for it).
