discovery of proton class 10
explain
Answers
Answer:
.The discovery of the proton is credited to Ernest Rutherford, who proved that the nucleus of the hydrogen atom (i.e. a proton) is present in the nuclei of all other atoms in the year 1917. Based on the conclusions drawn from the gold-foil experiment, Rutherford is also credited with the discovery of the atomic nucleus.
Answer:
Discovery of Protons
The discovery of protons dates back to the year 1815 when the English chemist William Prout suggested that all atoms are made up of hydrogen atoms (which he referred to as protyles). When canal rays (positively charged ions formed by gases) were discovered by the German physicist Eugen Goldstein in the year 1886, it was observed that the charge-to-mass ratio of the hydrogen ion was the highest among all gases. It was also observed that the hydrogen ion had the smallest size among all ionized gases.
The nucleus of the atom was discovered by Ernest Rutherford in the year 1911 in his famous gold foil experiment. He concluded that all the positively charged particles in an atom were concentrated in a singular core and that most of the atom’s volume was empty. He also stated that the total number of positively charged particles in the nucleus is equal to the total number of negatively charged electrons present around it.
