When rutherford discovered the atomic nucleus it develop which of the following ideas about the atom?
a. protons, neutrons, and electrons were evenly distributed throughout the atom.
b. the nucleus contained protons, neutrons and electrons.
c. the nucleus contained neutrons.
d. the nucleus contained positively-charged particles.

The correct answer is option D.

Explanation:

Rutherford gave an experiment known as gold foil experiment.

In his experiment, he took a gold foil and bombarded it with alpha particles (carrying positive charge). He thought that the particles will pass straight through the foil, but to his surprise, many of them passed through, some of them deflected their path and a few of them bounced back.

From this he concluded that in an atom, there exist a small positive charge in the center. Due to this positive charge, the alpha particles deflected their path and some of them bounced straight back their path.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
