What is the contribution of JJ Thomson?
A series of experiments with cathode rays he carried out near the end of the 19th century led to his discovery of the electron, a negatively charged atomic particle with very little mass. Thomson received the Nobel Prize in Physics in 1906 for his work exploring the electrical conductivity of various gases.
What could JJ Thomson conclude from his experiments?
Atoms are mostly empty space. Most of the mass of the atom is concentrated in the center. Atoms must balance positive and negative particles.
Who was a student of JJ Thomson?
When was Proton created?
IT STARTED WITH A BOLD IDEA IN 1979 In 1983, PROTON was formed, laying the foundations to the nation’s pride in the automotive industry.
Is Proton owned by China?
On 29 September 2017, DRB-HICOM announced changes to the board of Proton Holdings Berhad. Following the signing of a Definitive Agreement with China’s Zhejiang Geely Holding Group Limited on 23 June 2017, the Chinese carmaker acquired 49.9% equity in Proton.
Do Proton cars exist?
‘ Another said: ‘We are no longer a Proton dealer. Proton’s current state is a far cry from how it began 30 years ago. The car company, now owned by DRB-HICOM, started out in its home country of Malaysia in 1983 and produced the country’s first domestic car.
Is a proton positive?
Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite.
What gives a proton a positive charge?
The charge is believed to be from the charge of the quarks that make up the nucleons (protons and neutrons). A proton is made of two Up quarks, with 2/3 positive charge each and one Down Quark with a negative 1/3 charge (2/3 + 2/3 + -1/3 = 1).
What is inside of a quark?
A quark is a tiny particle which makes up protons and neutrons. Atoms are made of protons, neutrons and electrons. The flavours are up, down, strange, charm, top, and bottom. Up, charm and top quarks have a charge of +2⁄3, while down, strange and bottom quarks have a charge of -1⁄3.
What is inside of a neutron?
A neutron contains two down quarks with charge −1⁄3 e and one up quark with charge + 2⁄3 e. Like protons, the quarks of the neutron are held together by the strong force, mediated by gluons.
Is a proton mostly space?
Atoms are not mostly empty space because there is no such thing as purely empty space. Rather, space is filled with a wide variety of particles and fields. Even if we ignore every kind of field and particle except electrons, protons and neutrons, we find that atoms are still not empty.
Why is 99 empty space?
Atoms make up everything, but they also exist very, very far apart – and atoms themselves are more void than they are matter. Every atom has a nucleus surrounded by electrons. Every human on planet Earth is made up of millions and millions of atoms which all are 99% empty space.
