(c) State conclusions drawn from each observation of this experiment.
(d) State the model of atom suggested on the basis of the above experiment. (CBSE 2011)
Answer:
(a) Rutherford  Model
(b)  Rutherford made the following observations :

1. Most of the alpha particles were able to pass through the gold foil undeflected.
2. Some of these particles were deflected by small angles.
3. A very few (one out of approximately 12000) alpha particles suffered major deflections and even came back in the same direction.

(c) Conclusions

1. As most of the alpha particles passed through undeflected, this means that they did not come across any obstruction in their path. Thus, most of the space in an atom is expected to be empty.
2. As a few alpha particles suffered minor deflections and a very few major deflections, this means that these must have met with some obstructions in their path.
3. This obstruction must be :
   1. Very small : Only a few particles were obstructed by it.
   2. Massive : Each alpha particle has 4u mass and is quite heavy. It could easily pass through a light obstruction by pushing it aside.

(d) The main features are listed as follows :

1. An atom consists of two parts. These are nucleus and extra nuclear portion.
2. Nucleus is present in the centre of the atom and is surrounded by extra nuclear portion.
3. The radius of the nucleus of an atom is nearly 10^-15m while that of the atom is about 10^-10m. Thus, nucleus is very small in comparison to the atom.
4. The mass of the atom is mainly of the nucleus. All the protons and neutrons (discovered later on by Chadwick) are present in the nucleus.
5. The positive charge on the nucleus is because of protons present (each proton has one unit positive charge).
6. All the electrons are present in the extra-nuclear space around the nucleus.
7. The total positive charge of the nucleus due to the presence of protons is the same as that of the electrons present in the extra nuclear space. Therefore, the atom as a whole is electrically neutral.
8. Electrons present in the extra nuclear portion are not stationary. These are revolving around the nucleus at high speed following a circular path.
9. The revolving electrons do not come close to the nucleus or drawn towards the nucleus because their force of attraction towards the nucleus is balanced by the centrifugal force which is of the same magnitude. It is directed away from the nucleus

Question 10.
There are two elements ²⁶₁₃A and ²⁶₁₄B. Find the number of sub-atomic particles in each of these. What is the relation between these atoms ?
Answer:

Since the two elements have same mass number hut different atomic numbers, these are related to each other as isobars.

Question 11.
(a) In the gold foil experiment, what observations led Rutherford to conclude that
(i) Most of the space inside the atom is hollow.
(ii) The central portion of the atom is positively charged.
(iii) Volume occupied by the nucleus is very small as compared to the total volume of the atom.
(iv) Almost the entire mass of the atom concentrated at its centre.
(b) If bromine atom is available in the form of two isotopes ⁷⁹₃₅Br (49.7%) and ⁸¹₃₅Br (50.3%), calculate the average atomic mass of bromine atom. (CBSE 2014, 2016)
Answer:
(a) (i) Most of the α-particles passed through the foil undeflected.
(ii) Some α-particles (positively charged) were deflected and a few came back in the same direction. This means that there is very small, positively charged and massive portion present in the centre of the atom. This is known as nucleus.
(iii) The number of α-particles which were deflected back was very small.
(iv) Since the mass of the atom is mainly due to positively charged protons (neutrons were not known at that time), this means that the entire mass of the atom is concentrated in the centre of the atom called nucleus.
(b) % of Br isotope with mass number 79 = 49.7 % of Br isotope with mass number 81 = 50.3

Question 12.
State the postulates stated by Neils Bohr in order to overcome the objection as raised against Rutherford’s model of atom.
Answer:
The main postulates of the theory are listed :

1. In the extra nuclear portion of an atom, the electrons revolve in well defined circular paths known as orbits.
2. These circular orbits are also known as energy levels or energy shells.
3. These have been designated as K, L, M, N, O, … (or as 1, 2, 3, 4, 5, …) based on the energy present.
4. The order of the energy of these energy shells is :
   K<L<M<N<0 <…. or 1< 2< 3 < 4<5 <….
5. While revolving in an orbit, the electron is not in a position to either lose or gain energy. In other words, its energy remains stationary. Therefore, these energy states for the electrons are also known as stationary states.

Question 13.
Which of the following are isotopes and which are isobars ?
Argon, Protium, Calcium, Deuterium. Explain why the isotopes have similar chemical properties but they differ in physical properties ? (CBSE 2012)
Answer:
The symbol notations for elements are represented as follows :
¹₁H and ²₁H are isotopes while ⁴⁰₁₈Ar and ⁴⁰₂₀Ca are isobars. Since the isotopes of an element have same atomic number, they have same electronic configuration and also similar chemical properties. They have different physical properties since their mass numbers are different.

Question 14.
Explain Bohr and Bury rules for distribution of electrons into different shells.
Answer:

1. The maximum number of electrons which can be present in a particular energy shell of an atom is given by 2n². Here ‘n is the number of the energy shells or energy levels.
2. The outermost energy shell in an atom cannot have more than eight electrons even if it has a capacity to take up more electrons according to first rule.
3. It is not necessary for a given shell to complete itself before another shell starts forming. As a rule, the new shell is formed as soon as the outermost shell, acquires eight electrons.

(b) The scientist is Rutherford and the experiment is known as α-particle scattering experiment.

Question 36.
List the observations in α-particle scattering experiment which led Rutherford to make the following conclusions :
(i) Most of the space in an atom is empty,
(ii) Whole mass of an atom is concentrated in its centre.
(iii) Centre is positively charged. (CBSE 2015)
Answer:
(i) As most of the alpha particles passed through undeflected, this means that they did not come across any obstruction in their path. Thus, most of the space in an atom is expected to be empty.
(ii)  As a few alpha particles suffered minor deflections and a very few major deflections, this means that these must have met with some obstructions in their path.
This obstruction must be :

• Very small : Only a few particles were obstructed by it.
• Massive : Each alpha particle has 4u mass and is quite heavy. It could easily pass through a light obstruction by pushing it aside.

(iii) Positively charged : Alpha particles have positive charge. Since they were repelled or deflected back, the obstruction must also carry same charge i.e., positive charge, (similarly charged particles always repel each other).

Question 37.
Define isotopes. Why do isotopes have same atomic number but different mass numbers ? Explain with the help of an example. (CBSE 2015)
Answer:
Most of the elements exist in nature. An investigation of some of these have revealed that the atoms of a particular element may have different mass numbers. However, their atomic numbers are the same. These are called isotopes. Thus, isotopes may be defined as :
The different atoms of the same element having same atomic number but different mass numbers.
Please note that the difference in the mass numbers of the isotopes is because of the difference in the number of neutrons present. For example,
Hydrogen (H) exists in the form of three isotopes. These are named as :
