Covalent Bonds

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two nonmetal atoms share one or more pairs of electrons.

Front

What types of atoms typically form covalent bonds?

Back

Covalent bonds are typically formed between two nonmetals.

Front

What is an example of a molecule with a nonpolar covalent bond?

Back

O2 (oxygen gas) is an example of a molecule with a nonpolar covalent bond.

Front

How many valence electrons does nitrogen have?

Back

Nitrogen has 5 valence electrons.

Front

What does it mean if a bond is polar?

Back

A polar bond occurs when there is an unequal sharing of electrons between two atoms, resulting in a molecule with a slight electrical charge.

Front

What does it mean if a bond is nonpolar?

Back

A nonpolar bond occurs when two atoms share electrons equally, resulting in no charge difference across the molecule.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons.

Front

Which type of bond is formed between two metals?

Back

Metallic bonds are formed between two metals.

Front

What is the significance of valence electrons in covalent bonding?

Back

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

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.
