Ionic and Covalent Bonds

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a nonmetal.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two nonmetals 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 can an atom have at most?

Back

An atom can have a maximum of 8 valence electrons in its outermost shell.

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 an atom with 3 valence electrons when it forms bonds?

Back

An atom with 3 valence electrons is more likely to lose 3 electrons to achieve a full outer shell.

Front

What type of elements typically form ionic bonds?

Back

Ionic bonds typically form between metals and nonmetals.

Front

What type of elements typically form covalent bonds?

Back

Covalent bonds typically form between two nonmetals.

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.

Front

What is electronegativity?

Back

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