Earnest Rutherford's experiment,"Gold Foil", led to the discovery the of a Small,dense and positively charged Nucleus
Rutherford's experiment was important because it showed that an atom is mostly empty space. Rutherford gave more detail of the atom's structure.
The discovery of the noble gases led to the addition of the group 0, which is also designated as group 18/VIIIA.
Nucleus - Rutherford fired particles at gold foil, and most went straight through. This showed that most of atoms are empty, and that most of the mass only occupies a small part of the atom. This part is known as the nucleus.
When James Chadwick discovered the neutron, his discovery led to important revisions in the atom model. Chadwick's work with Ernest Rutherford partly allowed Rutherford to develop a model in which the nucleus consists of two types of nucleons--positively-charged protons and negatively-charged neutrons--surrounded by orbiting electrons.
Charles Darwin and his son did an experiment in 1880 using grass plants which led to the discovery of phototropism, this discovery led to many other scientists wanting to find out other tropisms
no
The gold-foil experiment led scientists to conclude that an atom's volume is mainly unoccupied.

Rutherford's gold foil experiment did not discover the existence of any subatomic particles, but it did show the existence of a small, tightly packed, positively charged nucleus and thus led to the discovery of protons.

The gold foil experiment supplanted the plum pudding theory. The gold foil experiment led to the discovery that most of the atoms mass is located in the dense nucleus.

Alpha particle ie doubly ionized helium atom scattering by the gold foil experiment formed the basis for the discovery of nucleus. The experiment was done by Marsden and Geiger but the experimental observation was commented and final conclusion derived by Rutherford.
Ddischarge tube led to the discovery of Cathode rays (electrons) and Positive rays (protons) so this discovery of cathode rays and positive rays can be considered as conse quences of discharge tube.
