Choose the correct description of J. J. Thomson's Model of an Atom.

The model is a indivisible and indestructible sphere

The model is a sphere in which negatively charged particles - electrons- immersed in a positively charged space of the sphere.

The model is a sphere in which negatively charged particles - electrons- move around the center of an atom creating an electron cloud

The model is a sphere in which negatively charged particles - electrons - move around the nucleus of an atom in a defined passes, called orbits, like planets around the sun

What results did Rutherford observe in his Gold-Foil experiment?

He observed that all alpha particles did go through a gold-foil in straight lines

He observed that most alpha particles did not go through a gold-foil and stopped on one side of the gold foil.

He observed that a small number of alpha particles bounced off the gold-foil at very large angles

He observed that all alpha particles slightly deflected from the straight line when going through a gold-foil
