Concepts of Ionic Bonding

What is the difference between cations and anions?

• Cations are positively charged ions, and anions are negatively charged ions.

• Cations are negatively charged ions, and anions are positively charged ions.

• Cations have a higher electron affinity than anions.

• Cations are larger in size compared to anions.

Explain how ionic bonds are formed between cations and anions.

• Ionic bonds are formed through metallic bonding between cations and anions.

• Ionic bonds are formed through electrostatic attraction between positively charged cations and negatively charged anions.

• Ionic bonds are formed through hydrogen bonding between cations and anions.

• Ionic bonds are formed through covalent bonding between cations and anions.

What are some properties of ionic compounds?

• High melting and boiling points, conductivity in solution, and crystalline structure

• Low melting and boiling points, insulating in solution, and amorphous structure

• Moderate melting and boiling points, conductivity in gas phase, and crystalline structure

• High melting and boiling points, non-conductivity in solution, and liquid structure

Describe the crystal lattice structure of ionic compounds.

• Positively and negatively charged ions are arranged in a repeating pattern to form a three-dimensional crystal lattice structure.

• Ions are randomly distributed in the crystal lattice structure

• The crystal lattice structure of ionic compounds is one-dimensional

• Ionic compounds do not have a crystal lattice structure

Why do cations have a positive charge?

• Cations have a positive charge due to the loss of electrons.

• Cations have a positive charge due to the gain of electrons.

• Cations have a positive charge due to the sharing of electrons.

• Cations have a positive charge due to the presence of protons.

How do anions acquire a negative charge?

• By sharing electrons

• By gaining electrons

• By gaining protons

• By losing electrons

What is the role of electron transfer in ionic bonding?

• Sharing of electrons between atoms

• Complete transfer of electrons from one atom to another

• Absence of electrons in the bonding process

• Transfer of protons instead of electrons

Why are ionic compounds typically solid at room temperature?

• Ionic compounds are solid at room temperature due to weak van der Waals forces holding the ions together.

• Ionic compounds are solid at room temperature due to their lack of crystal lattice structure.

• Ionic compounds are solid at room temperature due to their low melting points.

• Ionic compounds are solid at room temperature due to strong electrostatic forces holding the ions together.

What is the general formula for an ionic compound?

• Cation - Anion

• Cation x Anion

• Cation + Anion

• Anion + Cation

How do the properties of ionic compounds differ from those of covalent compounds?

• Covalent compounds are always solid at room temperature, unlike ionic compounds.

• Ionic compounds involve the sharing of electrons, resulting in ions with opposite charges, while covalent compounds involve the transfer of electrons between atoms.

• Ionic compounds have weaker bonds compared to covalent compounds.

• Ionic compounds involve the transfer of electrons, resulting in ions with opposite charges, while covalent compounds involve the sharing of electrons between atoms.
