Question

. On the basis of Thompson’s model of an atom, explain how the atom is neutral as a whole.

Answer 1

Answer:

As per Thompson’s model of an atom,

(i) An atom contains a positively charged sphere in which the negatively charged electrons are implanted.

(ii) Electrons and protons are equal in magnitude, hence an atom on the whole is electrically neutral

Hope it will be helpful.

Explanation:

The plum pudding model is one of several historical scientific models of the atom. First proposed by J. J. Thomson in 1904 soon after the discovery of the electron, but before the discovery of the atomic nucleus, the model tried to explain two properties of atoms then known: that electrons are negatively-charged particles and that atoms have no net electric charge. The plum pudding model has electrons surrounded by a volume of positive charge, like negatively-charged "plums" embedded in a positively-charged "pudding". The word "plums" in 19th-century English "plum pudding" is an archaic use of the word; it referred at that time to raisins, not plums.

1) According to Thomson model, an atom consists of a positively charged sphere and the negatively charged electron are embedded in it.

1) According to Thomson model, an atom consists of a positively charged sphere and the negatively charged electron are embedded in it.2) The negative and positive charges are equal in magnitude. So, the atom as a whole is electrically neutral.
