Ionic bonding

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically formed when one atom donates an electron to another.

Front

What is the general formula for an ionic compound?

Back

The general formula for an ionic compound is written with the positive ion (cation) first, followed by the negative ion (anion).

Front

What are the properties of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are soluble in water, and can conduct electricity when dissolved in water or molten.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed when an atom gains one or more electrons.

Front

How do ionic compounds conduct electricity?

Back

Ionic compounds conduct electricity when they are dissolved in water or melted, as the ions are free to move and carry an electric current.

What is the significance of valence electrons in ionic bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in the formation of chemical bonds. In ionic bonding, atoms transfer valence electrons to achieve a full outer shell.
