Ionic & Covalent Practice

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions that attract each other.

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 to achieve stability.

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 formula of a compound?

Back

The formula of a compound is determined by the ratio of the elements present, based on their valences and the type of bond (ionic or covalent) they form.

Front

What is the significance of subscripts in chemical formulas?

Back

Subscripts in chemical formulas indicate the number of atoms of each element in a molecule.

Front

What is the formula for sodium chloride?

Back

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 the name of the compound with the formula CO2?

Back

Carbon dioxide.

Front

What is the octet rule?

Back

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