Question

What did Rutherford conclude from his gold foil experiment?

Answer 1

Hint: We know atoms are the tiny particles in the world. Electrons and protons are present in the atom. Electrons revolve and rotate inside the atom in the orbitals. We aren't able to simultaneously study the position and moment of the electron in the atom. Generally particles are localized but waves are delocalised in space. Particles do not interfere with one another, but waves interfere.

Complete answer:
Rutherford performed his gold foil experiment. In this Rutherford used fast moving alpha particles as the projectile, to bombard the gold foil.
According to his experiment, Rutherford conclusion given below,
Rutherford's first conclusion is that the nucleus is smaller than the atom and second is that inside the atom electrons and nucleus are present. In the atom electrons revolve around the nucleus and rotate itself. The mass of the atom depends on the nucleus. The nucleus only has the maximum mass of the atom. The charge of the nucleus is positive and the charge of electrons is negative.

Note:
We have to remember that in the world there are a lot of elements in various forms. For study and developing purposes, classification happens. Periodic table used to study the elements in easy form. If one new element is discovered, it means, based on the physical and chemical property we placed in the periodic table. The atomic number of the element is nothing but the number of electrons or number of protons. The mass number of the atom is nothing but the sum of the number of protons and the number of neutrons. In general we move left to right metallic property of the atom decreases. We move right to left and non-metallic property decreases. In chemistry, periodic tables play a vital role. Now we are using a modern periodic table. This modern periodic table consists of totally $$118$$ elements. In the periodic table there are totally $$18$$ columns and $$7$$ rows. The columns are called groups. Hence, $$18$$ groups in the periodic table. The rows are called periods. Hence, totally $$7$$ period in the table.
