Why did Thomson assume that electrons are embedded in a positive mass but not the other way round ?

Text Solution

Verified by Experts

Thomson assumed that electrons are embedded in a positive mass as it could explain several observations like only electrons are ejected when a metal is heated and never positively charged particles.

Why did Thomson atom model fail?

Using Thomson's model of the atom, consider an atom consisting of two electrons, each of charge -e , embedded in a sphere ofcharge + 2e and radius R. In equilibrium each electron is at distanced from the centre of the atom. What is equilibrium separation between electrons ?

According to Thomson's model, every atom consists of a positively charged sphere of radius 10^(-10)m in which entire mass and positive charge of the atom are uniformly distributed. Inside the sphere, electrons are embedded like seeds in a watermelon. According Rutherford, entire positive charge and mass of the atom are concentrated in a tiny central core of the atom, which is called atomic nucleus. Size of nucleus ~~10^(-15)m . The nucleus contains proton and neutrons. Negatively charged electrons revolve around the nucleus in circular orbits. The size of atom is of the order of

In the Thomson's model of atom, which of the following statement are correct ? (i) The mass of the atom is assumed to be uniformaly distributed over the atom. (ii) The positive charge is assumed to be uniformaly distributed over the atom. (iii) The electrons are uniformaly distributed in the positively charged sphere. (iv) The electrons attract each other to stabilise tha atom.

If the entire mass of the body (45.5 kg) is assumed to be made up of electrons, how many electrons are present in mass of an electron is 9.1 xx 10^(-31) kg ?
