Explanation: Oppositely charged ions form a crystalline lattice which releases lattice energy.

• A. Have close packing
• B. Have low empty spaces
• C. Become less tightly held
• D. Have strong electrostatic forces

Explanation: Lattice energy is the energy released when ions come together to form a crystal lattice.

• A. Accept me and Della for what we are.
• B. Accept Della and me for what we are.
• C. Accept me and Della for what I am.
• D. Accept Della and me for what she is.

Explanation: The correct answer is 'Accept Della and me for what we are.' This option correctly uses 'Della and me' as the objects of the verb…

• A. Gamma Rays
• B. X-Rays
• C. Spectrometry
• D. Electron Microscope

Explanation: X-ray crystallography is a method of determining the 3d arrangement of atoms within a molecule.

• A. Cooling
• B. Heating
• C. Impurity
• D. None of these options are correct

Explanation: Option C is correct since the presence of impurity due to its different electronic structure causes the structure of the crystal to…

• A. Crystallite
• B. Unit cell
• C. Unit crystal
• D. Monomer

Explanation: A unit cell is the smallest unit of any crystal lattice. Unit cells keep repeating and making a whole lattice by generating repeatedly in…

• A. Inter-titian distance R
• B. Inter ionic distance R
• C. Inter cationic distance R +
• D. Inter-anionic distance R-

Explanation: The answer is B. Interionic distance for any ionic compound determines the extent of attraction of anions and cations.

• A. ABA
• B. ABC
• C. ABCD
• D. None of these

Explanation: a) ABA:The ABA arrangement pattern is known as the hexagonal close packing (HCP) structure.

• A. 1 only
• B. 1, 2 and 3
• C. 2 and 3 only
• D. 3 only

Explanation: The explanation for this question will be added soon.

• A. It is not a true solid
• B. It is attacked by HFl to make designs
• C. Pyrex is the type of glass used in laboratory apparatus
• D. It has a sharp melting point

Explanation: The explanation for this question will be added soon.

• A. Diamond is the hardest and graphite is softest
• B. Graphite is the hardest while lamp black is softest
• C. Coal is the hardest and coke is softest
• D. Diamond is the hardest and coke is softest

Explanation: Graphite is soft because it has weak intermolecular forces between its layers.

• A. Graphene
• B. Graphite
• C. Diamond
• D. Mercury

Explanation: It is as light as a feather, more than 100 times stronger than steel and a lightning conductor of electricity.

• A. Covalent
• B. Ionic
• C. Molecular
• D. Metallic

Explanation: It has a single type of atom and we have discussed above that among similar atoms covalent bonding is seen.

• A. Graphite
• B. Graphene
• C. Mercury
• D. Diamond

Explanation: It is as light as a feather, more than 100 times stronger than steel and a lightning conductor of electricity.

• A. Sodium chloride
• B. Copper sulphate
• C. Mercury
• D. Aluminium

Explanation: Aluminium metal is both malleable and ductile

• A. Cubic system
• B. Triclinic system
• C. Tetragonal system
• D. Monoclinic system

Explanation: Option A: In the cubic crystal system, all three axes (a, b, c) have equal lengths, and all angles (α, β, γ) are 90 degrees.

• A. Remain fixed
• B. Slip past each other
• C. Rotate
• D. Twist

Explanation: Metals are malleable and ductile because their layers slip past each other on applying pressure.

• A. Critical
• B. Absolute
• C. Transition
• D. None of these

Explanation: The temperature at which two crystalline forms of the same substance coexist in equilibrium with each other.

• A. Size
• B. Capacity
• C. Habit
• D. Property

Explanation: As defined, habit is the shape of a crystal in which it usually grows. This is because crystals are usually obtained by cooling the…

• A. Diamond
• B. Sulphur
• C. Ice
• D. Zinc

Explanation: Diamond is a giant molecular compound with a network of strong covalent bonds between the regularly arranged carbon atoms.
