Rutherford
Ernest Rutherford deduces the existence the atomic nucleus from alpha particle scattering experiments performed with Hans Geiger and Ernes Marsden.
This can refer to either the nucleus or to an individual proton that makes up the nucleus. Because only protons and neutrons occupy the nucleus, it has a positive charge.
Nucleus is the positively charged central core of the atom. It was discovered by Sir Rutherford during the alpha particle scattering experiment. But later by Sir Chadwick neutrons were also discovered along with protons in the nucleus. The nucleus is positively charged, small and is heavier than alpha particles.
He didn't exactly "discover" the nucleus. In 1911 he theorized about the atom having its positive charges in a very small nucleus. In 1921 he postulated about the existence of the neutron in the nucleus. The first experiment to split the atom in a controlled manner was performed by him and two students in 1932.
the scattering of light by colloids is known as tyndall effect. it is named after the scientist who discovered it.
The Raman effect, also known as Raman scattering, is the inelastic scattering of a photon. It was discovered by C. V. Raman and K. S. Kishnan in liquids. G. Landsberg and L. I. Mandelstam discovered it in crystals.
The atomic nucleus is positive because contain protons.
The (cell) nucleus is generally believed to have been discovered by Antonie van Leeuwenhoek. The nucleus of the atom was discovered by Ernest Rutherford.
positive
a Scottish botanist, discovered the presence of nuclei within cells.
Rutherford by passing interpretation about the famous alpha particle scattering experiment came to the conclusion that the positively charged nucleus is of small size of the order of 10-15 m where as the atom size is of the order of 10-11m
Yes. It was shown by Rutherford's alpha scattering experiment.
