Atomic Models

Rutherford’s Nuclear Model of Atom model is that the mass of the atom is assumed to be uniformly distributed over the atom.

The nucleus is surrounded by electrons that move around the nucleus with a very high speed in circular paths called _____.

Which one of the following are not the subatomic particles present in an atom?

The concept of atom based on experimental observation first came from:

"All matter is made up of very small particles which cannot be further broken down. These particles are called atoms". This statement is one of the assumptions of :

According to Dalton, atoms of different elements combine with one another to form:

Which of the following laws are in accordance with Dalton's atomic theory?

Which part of Dalton's original atomic theory must be modified with the discovery of isotopes?

Identify an isobar of ${}_6{}^{14}\mathrm{C}$ from the following elements.

Dalton's atomic theory was not able to explain which of the following:

According to Dalton's atomic theory, all matter is made of

Which of the following is an assumption of the Schrödinger model of the hydrogen atom?

Which of the following statements represent an incorrect limitation of Thomson's Atomic model?

Thomson's atomic model fails to explain the results of scattering experiments, carried out by _____.

Remaining part of atom except outer orbit is called:-
 

If the ratio of radius of two different nuclei are in the ratio of $2:3$, then ratio of their mass numbers will be

Atomic radius is of the order of ${10}^{-8} \mathrm{cm}$ and nucleus radius is of the order of ${10}^{-13} \mathrm{cm}.$ Calculate what fraction of atom is occupied by nucleus.

Rutherford's experiment on scattering of particles showed that an atom has
