Question

As a consequence of the discovery of the nucleus by rutherford, which model of the atom is thought to be true?

Answer 1

The correct answer is A.

Answer 2

Answer:

The correct answer is a. electrons are distributed around the nucleus and occupy almost all the volume of the atom.

Explanation:

Rutherford's experiment was to bombard a very thin sheet of gold (Au atoms) with alpha particles (positive charges). He thought that if the atom is composed by both negative and positive charges together (as Thompson had proposed) it would be electrically neutral and the positive charges would pass without deviation. He observed that most of the particles passed throught the sheet without deviation (as he expected) but several particles suffered a considerable deviation and others had bounced towards the emission source. So, he proposed a new atomic model in which the positive charge is concentred in the nucleus (alpha particles which passed nearly the nucleus were repelled with a considerable deviation) and surrounding the nucleus are the electrons (negative charge) which occupy a larger volume.
