Covalent Bonds Flashcard

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two non-metal atoms share pairs of electrons.

Front

What types of atoms typically form covalent bonds?

Back

Covalent bonds are typically formed between two non-metal atoms.

Front

Give an example of a covalent compound.

Back

An example of a covalent compound is methane (CH₄).

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is a covalent compound?

Back

A covalent compound is a chemical compound formed by the sharing of electrons between non-metal atoms.

Front

Identify a characteristic of covalent compounds.

Back

Covalent compounds usually have lower melting and boiling points compared to ionic compounds.

Front

What is the molecular formula for water?

Back

The molecular formula for water is H₂O.

Front

What type of bond is present in O₂ (oxygen gas)?

Back

O₂ has a covalent bond, as it consists of two oxygen atoms sharing electrons.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are shared unequally between the two atoms, resulting in a molecule with a slight charge.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of covalent bond where the electrons are shared equally between the two atoms.
