Ionic and 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 ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when one atom transfers electrons to another atom, resulting in the formation of positive and negative ions.

Front

What types of atoms typically form ionic bonds?

Back

Ionic bonds typically form between metals and nonmetals.

Front

What happens to an atom with 1 valence electron when it forms a bond?

Back

An atom with 1 valence electron is more likely to lose that electron to achieve a full outer shell.

Front

What do atoms that form positive ions tend to do?

Back

Atoms that form positive ions tend to lose electrons.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

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

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds with other atoms.

Front

How can you predict the type of bond between two elements?

Back

The type of bond can be predicted based on the difference in electronegativity between the two elements.

Front

What is electronegativity?

Back

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