Unit 4 Ionic and Covalent Bonding Review

Front

What are valence electrons?

Back

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

Front

What type of bond is formed when valence electrons are transferred?

Back

Ionic bonds are formed when valence electrons are transferred from one atom to another.

Front

What type of bond is formed when valence electrons are shared?

Back

Covalent bonds are formed when valence electrons are shared between atoms.

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding.

Front

What is a covalent compound?

Back

A covalent compound is a chemical compound formed by the sharing of electrons between atoms.

Front

What is a crystal lattice structure?

Back

A crystal lattice structure is a three-dimensional arrangement of atoms or ions in a crystal, typically found in ionic compounds.

Front

What is the dot diagram?

Back

A dot diagram (or Lewis dot structure) represents the valence electrons of an atom as dots around the element's symbol.

Front

What is the significance of the octet rule in bonding?

Back

The octet rule states that 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 the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the attraction between oppositely charged ions, while covalent bonds involve the sharing of electrons between atoms.

Front

What are some properties of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are soluble in water, and conduct electricity when dissolved in water.
