Ionic Bonding

What is an ion?

• An ion is an atom or molecule that has a net electrical charge due to the loss or gain of electrons.

• An ion is a type of gas that is commonly found in outer space.

• An ion is a type of subatomic particle that is smaller than an atom.

• An ion is a type of chemical bond that forms between two atoms.

How are positive ions formed?

• An atom loses one or more electrons.

• An atom gains one or more neutrons.

• An atom gains one or more protons.

• An atom gains one or more electrons.

How are negative ions formed?

• An atom gains one or more protons.

• An atom gains one or more electrons.

• An atom loses one or more electrons.

• An atom gains one or more neutrons.

What is an ionic bond?

• A chemical bond formed by the transfer of electrons between atoms.

• A chemical bond formed by the attraction of opposite charges between ions.

• A chemical bond formed by the sharing of electrons between atoms.

• A chemical bond formed by the combination of protons and neutrons in the nucleus of an atom.

What happens to electrons in an ionic bond?

• Electrons are transferred

• Electrons are gained

• Electrons are lost

• Electrons are shared

What is the difference between a cation and an anion?

• A cation and an anion have the same charge.

• A cation is a negatively charged ion, while an anion is a positively charged ion.

• A cation and an anion have the same number of electrons.

• A cation is a positively charged ion, while an anion is a negatively charged ion.

What are the properties of ionic compounds?

• Ionic compounds have high melting and boiling points, are usually solid at room temperature, and conduct electricity when dissolved in water or melted.

• Ionic compounds have high melting and boiling points, are usually liquid at room temperature, and do not conduct electricity when dissolved in water or melted.

• Ionic compounds have low melting and boiling points, are usually gas at room temperature, and conduct electricity when dissolved in water or melted.

• Ionic compounds have low melting and boiling points, are usually liquid at room temperature, and do not conduct electricity when dissolved in water or melted.
