Question

Hey mates ☺️

1 . Explain the drawbacks of Rutherford model .

2 . Give me some properties of Colloids and Suspension.

no spams ..☝️

Answer 1

The following are the drawbacksof Rutherford atomic model.

1) inability to explain the stabilityof atom

2) inability to explain the concept of electronic configuration and energy levels of shell

3) inability to explain the properties of atoms to form molecule

===}}}}the properties of suspension are as follow

suspension is a heterogeneous mixture.

the size of particles 1-100 nm.

it is unstable.

it does not show tyndall effect.

examples iron + water

===}}}the properties of colloids are as follow

it is a heterogeneous mixture.

the size of particles is intermediate between the size of true solution and suspension.

it is less stable.

it shows tyndall effect.

examples paint blood Ink.

✨ $<b>RUTHERFORD'S MODEL </b>$ ✨

♦️ The Rutherford model, also known as planetary model is a model which tried to describe an atom devised by Ernest Rutherford. Rutherford directed the famous Geiger–Marsden experiment in 1909 which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's plum pudding model of the atom was incorrect.

♦️ In many ways, the Rutherford model of the atom is the classic model of the atom, even though it's no longer considered an accurate representation. Rutherford's model shows that an atom is mostly empty space, with electrons orbiting a fixed, positively charged nucleus in set, predictable paths.

✨ $<b>Drawbacks </b>$ ✨

◾As per the electromagnetic theory, whenever a charged particle (like electron) is revolved around an oppositely charged centre (Protons of Nucleus), the particles continuously radiates energy. So, at sometime the electron will fall in the nucleus and the atom will collapse. But such a collapse does not occur. So, this model couldn't explain the stability of an atom.

◾Rutherford did not specify the orbits and the number of electrons revolving in each orbit.

◾This model could not explain the spectrum of Hydrogen.

That's it..
