Robert Brown discovered the nucleus while observing the cells of _____. View Solution. Q5.
According to Kinetic theory, the size of an atom is around 10 -10 m or around 10,000 to 100,000 times the size of the nucleus proposed by Rutherford. Hence, the distance of the electrons from the nucleus should be around 10,000 to 100,000 times the size of the nucleus. This eventually implies that most of the atom is empty space and explains ...
Robert Hooke in 1941. In eukaryotic cells, the nucleus is a double membrane covered protoplasmic body that contains heredity information. The nucleus was discovered by Robert Brown in 1831. With the help of grafting experiments on Acetabularia, Hammerling in 1953 proved that nucleus is a storehouse of hereditary information.
The nucleus is the command centre of a cell. This is because it contains the genetic material of the cell. Therefore, it consists of a number of structural elements which facilitate its functions. The nucleus of a cell has a spherical shape. A nucleus diagram is very useful for studying its structure. Its structure consists of the following ...
Describe Rutherford's scattering experiment about the discovery of the nucleus. Rutherford, in his experiment, directed high-energy streams of α-particles from a radioactive source at a thin sheet ( 100 nm thickness) of gold. To study the deflection caused to the α-particles, he placed a fluorescent zinc sulfide screen around the thin gold foil.
Antonie Philips van Leeuwenhoek (October 24, 1632 - August 30, 1723) who was a Dutch scientist first observed the cell nucleus, however, Robert Brown was a Scottish botanist who observed it in 1833, and gave it the name cell nucleus. Thus, the correct answer is option A.
Hence, this experiment led to the discovery of atomic nucleus. Was this answer helpful? 0. Similar ...

An atom’s nucleus comprises two major particles. An atom’s nuclei, these two types of stable particles are present and they are known as protons and neutrons. These subatomic particles are denoted by ‘p’ for proton and ‘n’ for neutron. The mass of the proton is slightly less than the mass of the neutron.
The correct option is A atomic nucleus Rutherford's alpha-particle scattering experiment was responsible for the discovery of atomic nucleus. Nucleus contains most of the mass. Most of the atom has empty space.
