Ionic Bonding STE 9

What is an ionic bond?

• An ionic bond is a type of bond formed by sharing electrons between atoms

• An ionic bond is a type of bond that involves the sharing of protons between atoms

• An ionic bond is a type of bond that involves the attraction between two nonpolar molecules

• An ionic bond is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions.

How is an ionic bond formed?

• An ionic bond is formed when two atoms repel each other due to opposite charges

• An ionic bond is formed when one atom transfers electrons to another atom, resulting in the attraction between the positively charged ion and the negatively charged ion.

• An ionic bond is formed when one atom transfers protons to another atom

• An ionic bond is formed when two atoms share electrons equally

What are the characteristics of ionic compounds?

• Ionic compounds are formed by the transfer of electrons between atoms, resulting in the formation of positive and negative ions. They have high melting and boiling points, conduct electricity when dissolved in water or melted, and have a crystalline structure.

• Ionic compounds do not conduct electricity in any form

• Ionic compounds have low melting and boiling points

• Ionic compounds are formed by the sharing of electrons between atoms

Explain the role of electron transfer in ionic bonding.

• Electron transfer in ionic bonding does not play a role in the formation of ions

• Electron transfer in ionic bonding only occurs in covalent bonding

• Ionic bonding involves the sharing of electrons between atoms

• In ionic bonding, electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions. This transfer of electrons creates an electrostatic attraction between the ions, leading to the formation of the ionic bond.

What are the properties of ionic compounds?

• Ionic compounds do not conduct electricity when dissolved in water or melted.

• Ionic compounds have low melting and boiling points.

• Ionic compounds are formed by the attraction between positively and negatively charged ions. They have high melting and boiling points, conduct electricity when dissolved in water or melted, and are often crystalline solids.

• Ionic compounds are formed by the attraction between positively and positively charged ions.

What is the difference between an ionic bond and a covalent bond?

• In an ionic bond, electrons are transferred from one atom to another, creating charged ions that are attracted to each other. In a covalent bond, electrons are shared between atoms.

• In an ionic bond, electrons are shared between atoms, while in a covalent bond, electrons are transferred from one atom to another

• In an ionic bond, atoms are attracted to each other due to the sharing of electrons, while in a covalent bond, atoms are attracted due to the transfer of electrons

• In an ionic bond, atoms share protons, while in a covalent bond, atoms share neutrons

Give an example of a compound formed by ionic bonding.

• Methane (CH4)

• Water (H2O)

• Sodium chloride (NaCl)

• Carbon dioxide (CO2)

What is lattice energy in the context of ionic bonding?

• Lattice energy is the energy required to break a solid crystal lattice into its constituent gaseous ions.

• Lattice energy is the energy released when covalent bonds form between atoms in a crystal lattice.

• Lattice energy is the energy released when gaseous ions form a solid crystal lattice.

• Lattice energy is the energy released when gaseous ions form a liquid crystal lattice.

Explain the concept of electronegativity in ionic bonding.

• In ionic bonding, electronegativity has no effect

• Electronegativity is the measure of an atom's size

• Electronegativity is the measure of an atom's ability to attract and hold onto electrons. In ionic bonding, electronegativity difference between two atoms determines the transfer of electrons, leading to the formation of ions and the bond between them.

• Electronegativity is the measure of an atom's positive charge

How do ionic bonds affect the physical properties of compounds?

• Ionic bonds have no effect on the physical properties of compounds

• Ionic bonds lead to low melting and boiling points in compounds

• Ionic bonds affect the physical properties of compounds by creating strong attractions between positively and negatively charged ions, leading to high melting and boiling points, as well as good electrical conductivity in the molten or dissolved state.

• Ionic bonds cause compounds to have poor electrical conductivity
