Question

explain Thomson's model of an atom​

Answer 1

Answer:

the atom is composed of electron srrounded by a soup of positive charge

to balance the electrons

Answer 2

Explanation:

The thompson's model of atom is origin of many other scientific models of atom...

The description of Thomson’s atomic model is one of the many scientific models of the atom. It was proposed by J.J Thomson in the year 1904 just after the discovery of electrons. However, at that time the atomic nucleus was yet to be discovered. So, he proposed a model on the basis of known properties available at that time. The known properties are:

1.Atoms are neutrally charged

2.Negatively charged particles called electrons are present in an atom. Learn about Charged particles in Matter in more detail here.

postulates of thompson's model of atom:

1.According to the postulates of Thomson’s atomic model, an atom resembles a sphere of positive charge with electrons (negatively charged particles) present inside the sphere.

2.The positive and negative charge is equal in magnitude and therefore an atom has no charge as a whole and is electrically neutral.

3.Thomson’s atomic model resembles a spherical plum pudding as well as a watermelon. It resembles a plum pudding because the electrons in the model look like the dry fruits embedded in a sphere of positive charge just like a spherical plum pudding. The model has also been compared to a watermelon because the red edible part of a watermelon was compared to the sphere having a positive charge and the black seeds filling the watermelon looked similar to the electrons inside the sphere.
