1. Iodine is needed for synthesis of thyroid hormone. 

2. If there is deficiency of iodine in the diet, it causes enlargement of thyroid gland leading to simple goitre. 

3. This disease is common in hilly areas hence it is also called endemic goitre. 

4. Addition of iodine to table salt prevents this disease. 

5. Therefore we must use iodised salt.

F > N > C > Si > B

P < Si < Be < Mg < Na

P < Si < Be < Mg < Na.

B < Al < Mg < K

Be shows diagonal relationship with Al

Correct option is (a) B < Al < Mg < K

O has the smallest radius.

Reason: An anion is formed when a neutral gaseous atom gains one or more electrons. This increases the number of electrons in the anion while its nuclear charge remains the same as that on the neutral atom. Since the same nuclear charge now attracts greater number of electrons of all the shells decreases. Hence the electron cloud of the atom expands. Hence O has small radius among O, O^- and O^2-

K⁺ = [Ar]

Sr²⁺ = [Kr]

Ar = [Ar]

Here Argon has the smallest radius because on moving down a group, there is an increase in the principal quantum number and thus, increases in the number of electron shells. Therefore, the atomic size is expected to increase. Hence, Argon has the smallest radius.

Al³⁺ is smallest because it has highest number of protons (13) among Na⁺, Mg²⁺, and Al³⁺ ions, due to which effective nuclear charge is maximum.

The largest species is Mg and the smallest one is Al³⁺.

Si has the smallest radius. In moving from left to the right in a period, the nuclear charge gradually increases by one unit and at the same time one electron is also being added in the election shell. Due to increased nuclear charge from left to right, the electrons are also getting more and more towards the nucleus. Consequently, the atomic size decreases in a period. Hence Si has the smallest radius.

Correct option is (d) Na⁺

a) The element with least atomic size is E. Because when we move from left to right in a period the atomic size decreases,

b) Electronic configuration of B is 1s² 2s² 2p⁶ 3s² 3p¹ Because the element belongs to 13th group its general configuration is ns² np¹ and the element belongs to third period and its atomic number is 13. Similarly electronic configuration of E is 1s² 2s² 2p⁶ 3s² 3p¹. Because the element belongs to 16th group. Its general configuration is ns2np4 and it is in third period. So its atomic number is 16. 

c) The elements which have similar physical and chemical properties with Y are X and Z. Because they lie in a single group, i.e. 1st group. In a group, elements are having similar physical and chemical properties. 

d) Z < Y < X < B < C < D < E.

A) Parliament

Correct option is  D) Cl^-

Actually it can .This is the way sulphuric acid is produced.First they burn Sulphur to produce Sulphur dioxide(SO2) then the So2 reacts with more oxygen to produce So3 and they react the So3 with sulphuric acid and water mixture to yeld more Sulphuric acid .The reason they dont dump the So3 in pure water is because the reaction is very exothermic and explosive so they use a solution of H2So4 and water instead .

Indian Constitution supported decentralization under article 40 to set up and expand Gram panchayats or local self-governance.

Correct option is B) Capitalism

Correct option is C) i, ii and iv

Amending the articles can be initiated only by the Parliament.

Anion is formed when one or more electrons are added to the valence shell of an atom. The added electrons will result in increased repulsion among the electrons and a decrease in effective nuclear charge. 

A) Both statements are true

(a)  1–K, 2 & 5– M, 3–J, 4–L

D) Nitrogen has less ionization energy compared to oxygen because it has stable half filled configuration.

Neutral oxides have no acidic or basic properties.

B) Keshavananda Bharati case

Task was to prepare the final draft taking into account all viewpoints.

B) Dr. B. R. Ambedkar

B) Cabinet Mission

A Drafting Committee was set up under the chairmanship of Dr. B.R. Ambedkar.

A) 29th Aug 1947

Correct option is B) D.S.Seth

D) both B and C

Correct option is  B) positive

Characteristics of the Indian Constitution :

1. Written Constitution : It took 2 years 11 months and 18 days to prepare the Constitution. 

2. Sovereignty : Sovereign power lies with the people of India. The Constitution has been made by the people, for the people and dedicated to the people of India. Thus, the supreme power is vested in the people. 

3. Federalism : Under this, the Constitution divides the powers between the Centre and the States through three lists: 

1. Union list, 

2. States list, 

3. Concurrent list.

Separation of Powers : The three organs of the state are the Legislature, the Executive and the Judiciary. 

1. The Legislature has the power to make laws.

2. The Executive has the power to execute laws. 

3. The Judiciary has the power to judge and apply punishment when laws are violated.

Mountbatten Plan.

Equal opportunities of employment to all irrespective of caste, race, colour, religion, etc., equality before law, abolition of untouchability, special provision of reservation for the backward classes.

Drafting Committee: A committee appointed by the Constituent Assembly for preparing the first draft of the Constitution.

In the Keshavanada Bharati case, it was argued that certain provisions in the Indian Constitution cannot be changed under any circumstances like Fundamental Rights.

1p and 3f are not possible. 

The possible orbitals are 2s, 2p.

Correct option is b. 0.40 nm

Given : 

Wavelength (λ) = 5894 Å, 

Velocity (ν) = 1.0 × 10⁸ ms^-1

To find : 

Mass of a particle

Formula : 

λ = \(\frac{h}{mv}\) or m = \(\frac{h}{\lambda v}\) 

(according to de-Broglie equation)

Calculation :

m = \(\frac{h}{\lambda v}\) 

∴ m = \(\frac{6.626\times 10^{-34}kg\,m^2s^{-1}}{(5894\times 10^{-10}m)\times (1.0\times 10^8 ms^{-1})}\) 

= 1.124 × 10^-35 kg

Mass of a particle is 1.124 × 10^-35 kg.

[Calculation using log table :

\(\frac{6.626\times 10^{-34}}{5894\times 10^{-10}\times 1.0\times 10^8}\) 

= \(\frac{6.626}{5894}\) x 10^-32

= Antilog₁₀[log₁₀6.626 – log₁₀5894] × 10^-32

= Antilog₁₀[0.8213 – 3.7704] × 10^-32

= Antilog₁₀ \(\overline{3} .0509\) x  10^-32

= 1.124 × 10^-35]

The basic and original rights given by the Constitution to all the citizens for their development.

Habeas Corpus, Mandamus, Prohibition, Quo warranto, Certiorari.

Four Fundamental Rights are as follows: 

1. Right to Equality: Equal opportunities of employment to all irrespective of caste, race, colour, religion etc., equality before law, abolition of untouchability, special provision of reservation for the backward classes. 

2. Right to Freedom : This includes 

1. the right to freedom of speech and expression,

2. the right to form associations, 

3. the right to move freely and reside in any part of the country, 

4. the right to choose any profession, occupation or business.

3. Right against Exploitation: Ban on the employment of children below the age of 14 years in hazardous places like mills or mines. 

4. Right to Freedom of Religion: All religions are alike and are free in their ways of worship, propagation and practice, no undue state interference.
