13.3 Give the postulates of the model discussed here.

13.4 Give one drawback of the atomic model .​

Answer 1

13.1 Correlation of the plum pudding with what Michael studied in his chemistry class is as follows:-

In chemistry class, Michael studied the model of atom proposed by J.J. Thomson- "plum pudding model"

13.2 The name "plum pudding" originate because:-

The model states that the in an atom, the negatively charged electrons are surrounded by a sphere of positive charge just as the the plums are embedded in a pudding.

13.3 Postulates of the model are as follows:-

• An atom consists of a positively charged sphere and negatively charged electrons are embedded in it.
• The positive and negative charges are equal in magnitude so the atom as a whole is electrically neutral.

13.4 Drawback of the atomic model

It failed to explain the stability of the atom as how a positive charge sphere can hold negatively charged electrons in an atom.
