Front

What does a Lewis Dot Structure represent?

Back

It shows the element's valence electrons and bonding capabilities.

Front

What is a polar covalent bond?

Back

A type of covalent bond where electrons are shared unevenly or unequally.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is electronegativity?

Back

A measure of the tendency of an atom to attract a bonding pair of electrons.

Front

What is a nonpolar covalent bond?

Back

A type of covalent bond where electrons are shared equally between two atoms.

Front

What is a molecule?

Back

A group of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound.
