Unit 5 Review - Bonding & Naming

Front

What is a nonpolar molecule?

Back

A nonpolar molecule is a molecule that has no overall dipole moment, meaning that the distribution of electron density is symmetrical, and it does not have distinct positive and negative ends.

Front

What are polar covalent bonds?

Back

Polar covalent bonds are chemical bonds where a pair of electrons is unequally shared between two atoms, leading to a slight charge difference across the molecule.

Front

What is a molecular solid?

Back

A molecular solid is a type of solid where the molecules are held together by intermolecular forces, such as van der Waals forces, rather than ionic or covalent bonds.

Front

What is the molecular formula for dinitrogen tetrahydride?

Back

The molecular formula for dinitrogen tetrahydride is N2H4.

Front

What is the formula for copper(I) oxide?

Back

The formula for copper(I) oxide is Cu2O.

Front

What is the IUPAC name for ZnO?

Back

The IUPAC name for ZnO is zinc oxide.

Front

What is the difference between ionic and covalent bonds?

Back

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

Front

What is a network solid?

Back

A network solid is a solid in which atoms are bonded by covalent bonds in a continuous network, resulting in a rigid structure.

Front

What is the significance of electronegativity in bonding?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons; it plays a crucial role in determining the type of bond (ionic, covalent, or polar covalent) formed between atoms.

Front

What is a metallic solid?

Back

A metallic solid is a solid composed of metal atoms that are held together by metallic bonds, characterized by a 'sea of electrons' that allows for conductivity and malleability.
