Results

#1. According to the dalton’s theory of atomic structure

Matter is made up of indestructible particles

Adams can combine with other atoms to form new substances

Atoms of a given element are identical

All of this

#2. Anatom consists of a tiny particle named nucleus whose size is______ the size of the item

100 times larger than

1,00,000 times smaller than

10 times smaller than

N times larger than

#3. Whose discovery implied the atom can’t be indestructible?

Rutherford's discovery of electron

Dalton's electronic structure

Thomson's discovery of electron

Giger Marsden's discovery of nucleus

#4. Choose the incorrect statement regarding the Sir JJ thomson’s atomic model

It is known as plum pudding model

According to the model an atom is spare having a uniform positive charge in which electrons are embedded

The model explained formation of ions and ionic compounds

Hold spare is uniformly negatively charged

#5. Detector used in Marsden experiment is

Zinc sulphide screen and microscope

One in 10,000

One in 1,00,000

One in 8000

#7. Alpha particle scattering is a consequence of

Nuclear force

Coulomb force

Gravitational force

Magnetic force

#8. Rutherford’s alpha particle experiment showed that the attempts have

Proton

Nucleus

Neutron

Electron

#9. And alpha particle moving with a constant energy is scattered by the nucleus the scattering angle with the maximum when the alpha particle

Approaches the nucleus ahead on

Just passes the nucleus

Passes at large distance from the nucleus

Is attracted by the nucleus

#10. Rutherford proposed his model of the atom in auto to explain the scattering of

Cathode rays

X rays

Alpha rays

Neutrons

#11. According to the classical theory the Rutherford atom was

Stable

Unstable

Semistable

Metastable

#12. Rutherford assumed in his atomic model that

The mass is concentrated at the centre

Charge mass is concentrated at the centre

Both the mass and energy are concentrated at the centre

Electrons are positively charged particle

#13. According to the Rutherford’s atomic model the electrons inside the atom

Stationary

Not stationary

Centralised

None of these

#14. The Rutherford’s alpha particle experiment shows that most of the alpha particles pass through almost unscattered while some are scattered through large angles what information does it give about the structure of the item

Atom is hollow

The whole mass of the atom is concentrated in a small centre called nucleus

Nucleus is positively charged

All the above

#15. The first member of any series in hydrogen atomic (electron jumps from quantum number P to N)

p=n+2

p=n+1

p=n-1

p=n-2

#16. With increasing quantum number the energy difference between adjacent energy levels in hydrogen atom

Decreases

Increases

Remains constant

Brackett series

#18. Which of the statements is incorrect as regards to hydrogen spectrum?

There are finite lines in Lyman series

There are finite lines in balmer series

There are infinite lines in microwave region

There are infinite lines in a toilet region

#19. If the mass of an electron is reduced to half the Rydberg constant

Remains uncharged

Becomes double
