J. J. Tomson was the discoverer of the electron. Using a cathode ray tube he found a particle that was deflected by a positively charged plate. Today we call cathode ray tubes televisions (at least the ones with picture tubes). He called the new particle a "corpuscle". Today we call it an electron (derived from the Greek word for "amber" which can be used to generate static electricity). Based on his research, he reasoned that the new particle had a negative charge. He proposed that an atom was like a mushy ball with raisins (electrons) stuck in the surface. Just like a tasty English holiday treat called Plum Pudding. Since atoms are usually electrically neutral (no charge), he reasoned that the mushy part had a positive charge (which would cancel the negative charge of the electron). Americans would say it was more like the electrons were Chocolate Chips in a scoop of chocolate chip ice cream or the chocolate chips in a scoop of chocolate chip cookie dough. (the repeated use of chocolate has nothing to do with the model). LA Dacanay
What else can I help you with?
Which one of daltons principles were contradicted by jj Thompson?
Dalton's principle that atoms are indivisible and cannot be further subdivided was contradicted by J.J. Thomson's discovery of the electron, which showed that atoms are made up of smaller subatomic particles.
What were JJ Thomson's discovery?
J.J. Thompson worked to develop the atomic theory. He discovered that atoms have separate negative and positive material. Before him, it was widely believed that atoms were just spheres of matter.
What is JJ Thomson model called?
J.J. Thomson, also known for discovering the electron, also proposed a model of the atom in 1904. This model is known as both the plum pudding model and the blueberry muffin model, and it posits that the atom is made up of electrons which are surrounded by a "pudding" of positive charges.
What piece of equipment did JJ Thomson use in his atomic theory experiment?
JJ Thomson used a cathode ray tube in his atomic theory experiment, known as the cathode ray experiment. By observing the behavior of cathode rays in the tube, he was able to discover the existence of electrons and propose the plum pudding model of the atom.
What did jj Thomas do?
JJ Thomas is an American professional snowboarder known for his achievements in competitive snowboarding. He won a bronze medal in the halfpipe event at the 2002 Winter Olympics and has been a prominent figure in the sport, showcasing his skills through various competitions and performances.

What was JJ Thomson famous for?

Who discovered electrons blue berry muffin model of atoms?
JJ Thomson
What did Thomson discover in the atom?
JJ Thomson discovered electrons, which showed that atoms are not indivisible.
Does jj like you?
no he does not like italians
What evedence convinced JJ Thomson that an atom consists of more than electrons?
The evidence for JJ Thomson was that the plum pudding model could not predict why atoms absorbed and emitted spectral lines.
When will Lil JJ appear on BET again?
NO one knows this but JJ hisself, but if like seeing him , you can catch him on Nickoleodon.
What findings led JJ Thomson to infer that particles are smaller than atoms do exist?
Particles are smaller
How do you beast?
learn how to mosh. ask jj. or np. or look up, how to mosh.
What did thompson contribute in forming the modern model of the atom?
JJ Thomson discovered that atoms were not indivisible because he discovered that atoms contained negatively charged subatomic particles which he called electrons.
