What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. They typically form between metals and nonmetals.

Front

Which chemical formula represents an ionic compound?

Back

Examples of ionic compounds include MgO (magnesium oxide), CaCl2 (calcium chloride), and Li2S (lithium sulfide). CH4 (methane) is not an ionic compound.

What types of compounds dissolve easily in water?

Back

Polar and ionic compounds dissolve easily in water due to their ability to interact with water molecules.

Front

How are ionic bonds formed?

Back

Ionic bonds are formed through the transfer of electrons from one atom to another, resulting in the formation of positively and negatively charged ions.

Front

What is a cation?

Back

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

Front

What is an anion?

Back

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

Front

What is the Octet Rule?

Back

The Octet Rule states that atoms tend to react in order to achieve a full outer shell of 8 electrons, which provides stability.

Front

What is the difference between polar and nonpolar compounds?

Back

Polar compounds have a significant difference in electronegativity between atoms, leading to a dipole moment, while nonpolar compounds have an even distribution of charge.

Front

What is the significance of electronegativity in bond formation?

Back

Electronegativity determines how strongly an atom attracts electrons in a bond, influencing whether the bond will be ionic or covalent.

Front

What is a covalent bond?

Back

A covalent bond is formed when two atoms share one or more pairs of electrons, typically between nonmetals.
