What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two nonmetal atoms share 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 formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a nonmetal.

Front

What is the role of electrons in bonding?

Back

Electrons are the subatomic particles that are involved in the formation of chemical bonds between atoms.

Front

How many valence electrons do elements in group 14 have?

Back

Elements in group 14 have 4 valence electrons.

Front

What happens to atoms that form positive ions?

Back

Atoms that form positive ions tend to lose electrons.

Front

Is hydrogen a metal or a non-metal?

Back

Hydrogen is considered a non-metal.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

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 electronegativity?

Back

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