Ionic and Covalent Bonds

Front

What are covalent bonds?

Back

Covalent bonds are chemical bonds formed between two nonmetals, where they share pairs of electrons.

Front

What do group numbers on the periodic table indicate?

Back

Group numbers on the periodic table help us determine the number of valence electrons in an element.

Front

Where are metals located on the periodic table?

Back

Metals are primarily located on the left side and in the center of the periodic table, often represented in blue.

Front

What are ionic bonds?

Back

Ionic bonds are chemical bonds formed between a metal and a nonmetal, where electrons are transferred from one atom to another.

Front

What type of bond is represented by CaCl?

Back

CaCl represents an ionic bond.

Front

What is a valence electron?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another (metal to nonmetal), while covalent bonds involve the sharing of electrons between nonmetals.

Front

What is an example of a covalent compound?

Back

An example of a covalent compound is water (H2O), where hydrogen and oxygen share electrons.

Front

What is an example of an ionic compound?

Back

An example of an ionic compound is sodium chloride (NaCl), formed from sodium and chlorine.

Front

How do you determine the type of bond between two elements?

Back

The type of bond can be determined by the elements' positions on the periodic table: metals typically form ionic bonds with nonmetals, while nonmetals form covalent bonds with each other.
