In which of the following solids, ions of opposite charges are held together by strong electrostatic forces of attraction?
Therefore, the correct answer is B.
Which of the following crystalline solids have highest melting point?
Diamond has a very high melting point (almost 4000°C) due to very strong carbon-carbon covalent bonds having to be broken throughout the structure before melting occurs.
Amorphous solids are also known as:
What are the basic particles of ice crystals?
Basic particle forming ice crystals are water molecules. It is a molecular crystal.
Water molecules are arranged in a cage-like structure orderly array resulting in a crystalline structure.
Why some of the physical properties of solids show different values when measured along different directions in the same crystals?
Which of the following properties is generally exhibited by amorphous solids?
Hence, the correct answer is Glass transition.
Which of the following is NOT a molecular solid?
A diamond is not considered a molecule because each carbon atom is covalently bonded with four other carbon atoms. This is what makes a diamond a network solid.
Hydrogen bonding occurs in which type of crystalline solids?
Molecular solids consist of atoms or molecules held to each other by dipole-dipole interactions, London dispersion forces, hydrogen bonds, or any combination of these.
Additional Information: Hydrogen bonding refers to the formation of Hydrogen bonds, which are a special class of attractive intermolecular forces that arise due to the dipole-dipole interaction between a hydrogen atom that is bonded to a highly electronegative atom and another highly electronegative atom which lies in the vicinity of the hydrogen atom.
Which of the following is an amorphous solid?
Why ancient glass becomes milky?
Which is not a characteristic of crystalline solids?
Characteristics of Crystalline solids:
On the other hand, isotropy is a characteristic of amorphous solid. Therefore, it is an incorrect statement. The correct answer is D.
Potassium chloride is:
Potassium chloride is an ionic compound.
Since, potassium is a metal and chlorine is a non-metal and if a metal is mixed with a non-metal it gives an ionic compound.
Which type of solids are held by weak dispersion forces?
In non-polar molecular solids, molecules are held by weak dispersion forces or London forces.
Silicon is found in nature in the forms of ________.
Which state of matter is incompressible?
Solid-state of matter is incompressible because the distance between the constituent particles is very less in solids.
Why do metallic solids conducts electricity?
Thus, metals are good conductors of electricity.
Dry ice is an example of:
Dry ice is solid carbon dioxide which is generally used in packing frozen items is an example of molecular solid.
What are the basic constituent particles forming diamond crystals?
In diamond, carbon atoms are joined together by strong covalent bonds tetrahedrally which makes it an atomic crystal.
Hence, the correct answer is Atoms.
A friend in your chemistry class is struggling to understand why crystalline solids are grouped into four main types: network, molecular, ionic, and metallic. Which explanation below will BEST help him begin to understand why chemists might have these groups?
Therefore, the correct answer is D.
Which of the following is a non-conductor in solid state but good conductor in molten state?
Which of the following properties is NOT exhibited by metallic solids?
Among the following solids, which one shows the strongest bonding?
Why ice is a crystalline compound?
Crystalline compounds are those in which particles/molecules are arranged in proper order as in ice particles/water molecules are arranged in a cage-like ordered manner so this ordered structure is called a crystalline compound.
Which of the following is a covalent crystal?
The points which shows the position of atoms in a crystal are called as _________.
