Which of the following conclusions regarding the structure of atom is based on Rutherford’s α-particle scattering experiment?

Detailed Solution: Question 1

As a very few α-particles were deflected by sharp angles, it was concluded that the positive charge is concentrated in a very small volume of the atom.

Test: Atomic Models - Question 2

Which of the following observations was not correct during Rutherford’s scattering experiment?

Detailed Solution: Question 2

Very few of bombarded α-particles on gold foil were deflected by sharp angles and therefore, it was concluded that the positive charge is concentrated in a very small volume of the atom called nucleus. Since few were deflected, the size of the nucleus is very small as compared with atom size.
Most of the particles passed through the foil undeflected and was concluded that most of the space in an atom is empty.

An element with mass number 81 contains 31.7% more neutrons as compared to protons. Find the symbol of the atom

Detailed Solution: Question 4

Mass number of the element = 81
i.e., p + n = 81
Let the number of protons be x.
Number of neutrons 


Symbol of the element

Test: Atomic Models - Question 5

Which of the following species is isoelectronic with CO?

Detailed Solution: Question 5

Isoelectronic species means species having same number of electrons.
In CO; no. of electrons = 6 + 8 = 14
In N2; no. of electrons = 7 + 7 = 14
