Chemical Bonding

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.

Front

What are the two main types of chemical bonds?

Back

The two main types of chemical bonds are ionic bonds and covalent bonds.

Front

What is an ionic bond?

Back

An ionic bond is formed when one atom transfers electrons to another atom, resulting in the formation of oppositely charged ions.

Front

What is a covalent bond?

Back

A covalent bond is formed when two atoms share one or more pairs of electrons.

Front

What are valence electrons?

Back

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

Front

How many valence electrons does Calcium (Ca) have?

Back

Calcium (Ca) has 2 valence electrons.

Front

What group in the periodic table does Calcium (Ca) belong to?

Back

Calcium (Ca) belongs to Group 2 of the periodic table.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

What happens to the charges of ions in an ionic bond?

Back

In an ionic bond, positive and negative charges attract each other, forming a stable compound.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally, while nonpolar covalent bonds occur when electrons are shared equally.
