The Nobel Prize in Physics 1933 was awarded jointly to Erwin Schrödinger and Paul Adrien Maurice Dirac “for the discovery of new productive forms of atomic theory.”
Q. Did Werner Heisenberg win a Nobel Prize?
The Nobel Prize in Physics 1932 was awarded to Werner Karl Heisenberg “for the creation of quantum mechanics, the application of which has, inter alia, led to the discovery of the allotropic forms of hydrogen.” Werner Heisenberg received his Nobel Prize one year later, in 1933.

Q. What did Werner Heisenberg think the atom looked like?
The prevailing quantum theory in the early 1920s modeled the atom as having electrons in fixed quantized orbits around a nucleus. Heisenberg objected to the current model because he claimed that since one couldn’t actually observe the orbit of electrons around a nucleus, such orbits couldn’t really be said to exist.
Q. Who found the nucleus?
Ernest Rutherford’s
Q. Who found the proton?
Proton
| The quark content of a proton. The color assignment of individual quarks is arbitrary, but all three colors must be present. Forces between quarks are mediated by gluons. | |
|---|---|
| Classification | Baryon |
| Discovered | Observed as H+ by Eugen Goldstein (1886). Identified in other nuclei (and named) by Ernest Rutherford (1917–1920). |
Q. What charge is a proton?
Proton—positive; electron—negative; neutron—no charge. The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another in a neutral atom.
Q. What is the weight of one proton?
Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.
Q. What is the unit of weight?
newtons
Q. What is mass of a neutron?
Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
Q. Are electrons positive or negative?
Inside an atom are protons, electrons and neutrons. The protons are positively charged, the electrons are negatively charged, and the neutrons are neutral. Therefore, all things are made up of charges. Opposite charges attract each other (negative to positive).
