Properties of Ionic and Covalent Compounds

What is an binary ionic compound?

• A compound composed an anion and cation.

• A compound that contains only metal elements.

• A chemical compound composed of covalent bonds.

• A compound that contains only non-metal elements.

What is a binary covalent compound?

• a compound formed by the transfer of electron pairs between atoms.

• a compound formed by the attraction of opposite charges between atoms.

• a compound formed by two different elements and the sharing of electron pairs between atoms.

• a compound formed by the repulsion of like charges between atoms.

What are the properties of ionic compounds?

• Ionic compounds have low melting and boiling points, are usually liquid at room temperature, are often insoluble in water, do not conduct electricity when dissolved in water or melted, have an amorphous structure, and are composed of cations and anions.

• Ionic compounds have high melting and boiling points, are usually solid at room temperature, are often soluble in water, conduct electricity when dissolved in water or melted, have a crystalline structure, and are composed of cations and anions.

What are the properties of covalent compounds?

• Covalent compounds have low melting and boiling points, are usually solids at room temperature, and do not conduct electricity in their pure form.

• Covalent compounds have high melting and boiling points, are usually gases or liquids at room temperature, and conduct electricity in their pure form.

• Covalent compounds have low melting and boiling points, are usually gases or liquids at room temperature, and do not conduct electricity in their pure form.

• Covalent compounds have high melting and boiling points, are usually solids at room temperature, and conduct electricity in their pure form.

How are ionic compounds formed?

• Through the sharing of electrons between atoms.

• Through the transfer of electrons between atoms.

• Through the attraction of opposite charges.

• Through the formation of covalent bonds.
