Ionic and Covalent Bonds

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when one atom transfers electrons to another atom, resulting in the formation of 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.

Front

What is the octet rule?

Back

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

Front

What are the characteristics of ionic compounds?

Back

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

Front

What are the characteristics of covalent compounds?

Back

Covalent compounds usually have lower melting and boiling points, may not be soluble in water, and do not conduct electricity.

Front

Where are metals located on the periodic table?

Back

Metals are located on the left side and in the center of the periodic table.

Front

Where are nonmetals located on the periodic table?

Back

Nonmetals are located on the right side of the periodic table.

Front

What is the Lewis structure?

Back

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

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 polar and nonpolar covalent bond?

Back

A polar covalent bond occurs when electrons are shared unequally between atoms, while a nonpolar covalent bond occurs when electrons are shared equally.
