Ionic Compounds and Valency

Front

What are ionic compounds?

Back

Ionic compounds are chemical compounds composed of ions held together by electrostatic forces termed ionic bonding.

Front

What is valency?

Back

Valency is the measure of the ability of an atom to bond with other atoms, often determined by the number of electrons in the outer shell.

Front

What are charges in ionic compounds?

Back

Charges in ionic compounds refer to the positive or negative electrical charge of the ions, which results from the loss or gain of electrons.

Front

How do you write the chemical formula for an ionic compound?

Back

The chemical formula for an ionic compound is written by combining the symbols of the constituent ions, with the cation (positive ion) first, followed by the anion (negative ion), and balancing the charges.

Front

What is an example of an ionic compound?

Back

An example of an ionic compound is sodium chloride (NaCl), commonly known as table salt.

Front

How do ionic bonds form?

Back

Ionic bonds form when one atom transfers electrons to another atom, resulting in the formation of positively and negatively charged ions that attract each other.

Front

What properties do ionic compounds exhibit?

Back

Ionic compounds typically exhibit high melting and boiling points, electrical conductivity when dissolved in water, and are usually soluble in water.

Front

How do ionic compounds differ from covalent compounds?

Back

Ionic compounds are formed by the transfer of electrons between atoms, resulting in charged ions, while covalent compounds are formed by the sharing of electrons between atoms.
