Protons & Neutrons
Flashcards do conjunto (8)
- 1Protons are positively charged and have the symbol of \(p^+\)They have a charge of \(1.602×10^-19\) Coulomb - The standard unit of charge
- 2They are extremely light and smallThey weigh \(1.672×10^-27\) Kg, and have a radius of about \(10^-15\) m
- 3The name proton was given by Ernest Rutherford in 1920Hydrogen is the only element to have just one proton in its atom
- 4The number of protons in an atom define the atomic number of that atomYou can then figure out what element that atom is from
- 5Neutrons are neutrally charged, and have the symbol nBecause they are neutral, it is very hard to detect neutrons
- 6They are slightly heavier than protonsBoth the neutron and the proton are found in the nucleus of the atom
- 7Apart from hydrogen, every atom nucleus is made up of protons and neutronsThe neutrons are important because they bind the protons together with nuclear force
- 8Ernest Rutherford also suggested the theory of neutrons, but he did not discover themThey were discovered by James Chadwick in 1932
