Write the findings of Bohr in the Bohr atomic model

Neil Bohr Model of Atom Bohr Discovery Neil Bohr presented a model of atomic structure in 1913, known as Bohr’s atomic model, which depicted an atom as a tiny, positively charged nucleus surrounded by electrons that move in circular orbits around the positively charged nucleus like planets do around the sun in our solar system. …

What were the observations of Rutherford’s experiment?

Rutherford’s Experiment Discoverer In 1911 Rutherford experimented to know about arrangements of sub-atomic particles such as electrons and protons in an atom. Rutherford’s Gold Foil Experiment First of all, Rutherford took a gold foil of about 4×10-5cm and bombarded alpha particles on it. Alpha particles are helium nuclei with two protons and two neutrons present …
