Who invented the atoms have protons and electrons?
albert Einstein
Which inventor made electrons?
A electron is one of the 3 things you need to complet a ATOM. getting back to the subject , so a electron is a thing in the ELECTRON CLOUD.
Who is jj tompson?
He is the one who discovered electrons , isotopes and invented the mass spectrometer .
What kind of father in science jj Thomson?
He discovered electrons, isotopes, and invented the mass spectrometer.
Who invented the bohr diagram?
The Bohr diagram was invented by Niels Bohr, a Danish physicist, in 1913. He used this diagram to depict the arrangement of electrons in an atom's energy levels.
When were exrays invented?
X-rays were invented in 1895 by German physicist Whilhen Conrad-Rontgen. He discovered the fluorescent screen glowed while experimenting with electrons in his lab.
Who invented the scanning tunneling microscope?
a scanning tunneling microscope measures electrons that leak, or 'tunnel', fromthe surface of specimen
Who invented the Bohr model and what does it look like?
Niels Bohr created this model; electrons move around the positive atomic nucleus.
Was the electron microscope invented by a Canadian?
No, the electron microscope was not invented by a Canadian. The electron microscope was invented by German physicist Ernst Ruska in 1931, along with Max Knoll. The invention revolutionized microscopy by using a beam of electrons to illuminate specimens, allowing for much higher magnification and resolution compared to traditional light microscopes.
The emission of electrons in high-vacuum tubes is caused by?
The heating by the filament causes the electrons to "boil off". Edison noted this phenomena and it was later picked up by Fleming who used a "grid" which could control the flow of the electrons by introducting a repelling field between the Cathode (heated element that emitted the electrons) and the anode that attracted the free electrons, thus the "Fleming Valve" was invented (the vacuum tube.
Who invented the first electron microscope?
The first electron microscope was invented by Max Knoll and Ernst Ruska in 1931. They were able to achieve much higher magnification than traditional light microscopes by using electrons instead of light to image specimens.
Who invented that electron is outside of the nucleus?
Ernest Rutherford's gold foil experiment in 1909 demonstrated that atoms have a small, dense nucleus at their center with electrons orbiting around it, suggesting that electrons are outside of the nucleus. This experiment led to the development of the planetary model of the atom.
