who discovered electrons​

Answer 1

Answer:

ᴊ. ᴊ ᴛʜᴏᴍsᴏɴ ᴅɪsᴄᴏᴠᴇʀᴇᴅ ᴇʟᴇᴄᴛʀᴏɴs

$\small\underbrace\mathbb\orange{explanation} \:$

During the 1880s and ’90s scientists searched cathode rays for the carrier of the electrical properties in matter. Their work culminated in the discovery by English physicist J.J. Thomson of the electron in 1897. The existence of the electron showed that the 2,000-year-old conception of the atom as a homogeneous particle was wrong and that in fact the atom has a complex structure.

J.J. Thomson is widely recognized as the discoverer of the electron. Thomson was the Cavendish professor of Experimental Physics at Cambridge University and director of its Cavendish Laboratory from 1884 until 1919. For much of his career, Thomson worked on various aspects of the conduction of electricity through gases. In 1897 he reported that "cathode rays" were actually negatively charged particles in motion; he argued that the charged particles weighed much less than the lightest atom and were in fact constituents of atoms [Thomson 1897a, 1897b]. In 1899, he measured the charge of the particles, and speculated on how they were assembled into atoms [Thomson 1899]. He was awarded the Nobel Prize for physics in 1906 for this work, and in 1908 he was knighted. His Nobel lecture is reproduced below.

The case of the electron raises several interesting points about the discovery process. Clearly, the characterization of cathode rays was a process begun long before Thomson's work, and several scientists made important contributions. After all, he did not invent the vacuum tube or discover cathode rays. Discovery is often a cumulative process. The credited discoverer makes crucial contributions to be sure, but often after fundamental observations have been made and tools invented by others. Thomson was not the only physicist to measure the charge-to-mass ratio of cathode rays in 1897, nor the first to announce his results. But Thomson did carry out this measurement and (later) the measurement of the particles's charge, and he recognized its importance as a constituent of ordinary matter.
