Ionic and Covalent Compounds

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 between a metal and a non-metal.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons, usually between non-metal atoms.

Front

What is the Lewis structure?

Back

The Lewis structure is a diagram that represents the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

How do you determine the chemical formula of an ionic compound?

Back

The chemical formula of an ionic compound is determined by the ratio of the ions that make up the compound, ensuring that the total charge is neutral.

Front

What is the significance of the octet rule in bonding?

Back

The octet rule states that atoms tend to form bonds in such a way that they each have eight electrons in their valence shell, achieving a stable electron configuration.

Front

Which elements typically form ionic bonds?

Back

Ionic bonds typically form between metals (which lose electrons) and non-metals (which gain electrons), such as sodium (Na) and chlorine (Cl).

Front

What is the chemical formula for sodium chloride?

Back

The chemical formula for sodium chloride is NaCl.

Front

What is the difference between a molecular compound and an ionic compound?

Back

Molecular compounds consist of molecules formed by covalent bonds, while ionic compounds consist of ions held together by ionic bonds.

Front

What is a polyatomic ion?

Back

A polyatomic ion is a charged entity composed of two or more atoms covalently bonded together, which can act as a single unit in chemical reactions.

Front

How do you name ionic compounds?

Back

Ionic compounds are named by stating the name of the metal (cation) first, followed by the name of the non-metal (anion) with its ending changed to '-ide'.
