What else can I help you with?
How are cathode rays originated?
its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
What did the cathode ray tube tell us about atomic structure?
because Thomson saw the ray move from the cathode to the anode so the particles have negatively charge
Which scientist did experiments involing a form of cathode ray tube?
J.J. Thomson used cathode ray tubes to prove the existence of electrons.
What are ionized particles?
Ionised particles are particles that carry a positive or negative charge. This is due to the loss or gain of an electron or electrons. Losing an electron will cause a particle to become more positively charged, while gaining an electron will cause a particle to become more negatively charged.
What are the role of cathode tubes in atom?
cathode tubes were used to detect the particle in an atom & found that negatively charged particles(electrons) are there in an atom.
Who discovered small negatively charged particles inside an atom?
J.J Thomson
Who invented the negatively charged particle electron?
The negatively charged particle electron was discovered by J.J. Thomson in 1897 through his experiments with cathode rays. Thomson's experiments led him to propose the existence of the electron as a fundamental subatomic particle.
Which scientist used a cathode ray tube to discover negatively charged subatomic particles?
The scientist who used a cathode ray tube to discover negatively charged subatomic particles was J.J. Thomson.
Which scientist discovered that cathode rays are made up of negatively charged particles?
J.J. Thomson discovered that cathode rays are made up of negatively charged particles. He conducted experiments using cathode ray tubes and found that the rays were deflected by electric and magnetic fields in a manner consistent with the presence of negatively charged particles.
Who Discovered that atoms contain negatively charged particles called electrons?
In 1897, a British scientis named J.J. Thomson.
Who discovered that there are small negatively charged particles inside an atom?
J.J. Thomson discovered the existence of small negatively charged particles, later named electrons, inside an atom through his cathode ray tube experiments in 1897. This discovery laid the foundation for the development of the atomic model.
How did J.J. Thomson discover negative charges?
J.J. Thomson discovered negative charges by studying cathode rays in a vacuum tube, where he observed that they were deflected by electric and magnetic fields in a way consistent with negatively charged particles. This led him to propose the existence of negatively charged particles, which he later named electrons.
How did Thomson know that the glow in the CTR was from a stream of charged particles?
Thomson knew that the glow in the cathode ray tube (CRT) was from a stream of charged particles because the particles were deflected by electric and magnetic fields, indicating they were negatively charged. By measuring the deflection of the particles, he was able to calculate the charge-to-mass ratio of the particles, leading to the discovery of the electron.
Why did J Thomson reason that electrons must be a part of the atoms of all elements?
Cathode rays are negatively-charged particles.
Negatively charged particles are called what?
Negatively charged particles are called electronsI'M SURE BELIEVE ME !!!!electrons are charged -1 and protons are charged +1.
What Thomson called corpuscles are now called what?
What Thomson called corpuscles are now referred to as electrons.
When Thomson held a positively charged plate near the cathode ray the beam bent toward the plate What conclusion can be drawn from this observation?
The beam bending towards the positively charged plate indicates that the cathode rays are negatively charged. This observation led Thomson to conclude that the cathode rays are made up of negatively charged particles, which we now know as electrons.
