Lewis Structures and Compound types

Front

What is a Lewis Structure?

Back

A Lewis Structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

Front

What do dots represent in a Lewis Structure?

Back

Dots represent valence electrons in a Lewis Structure.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form compounds in ways that give them eight valence electrons, achieving a stable electron configuration.

Front

What type of bond forms when pairs of electrons are shared between two nonmetal atoms?

Back

Covalent bond.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

Which group of elements is known for being stable and unreactive?

Back

Noble gases.

Front

What is the significance of electronegativity in bond formation?

Back

Electronegativity determines how strongly an atom attracts electrons; a large difference in electronegativity between two atoms can lead to ionic bonding.

Front

What is a dot diagram?

Back

A dot diagram, or Lewis dot structure, visually represents the valence electrons of an atom and how they are involved in bonding.

Front

Are prefixes used in naming ionic compounds?

Back

No, prefixes are not used in naming ionic compounds.

Front

What is the correct dot diagram for oxygen (O)?

Back

The correct dot diagram for oxygen shows six dots around the symbol, representing its six valence electrons.
