AP CHEM: Inter, Intramolecular, Potential Energy and Alloys

Front

What is an alloy?

Back

An alloy is a mixture of two or more elements, where at least one is a metal, designed to have specific properties.

Front

Which types of elements typically become cations?

Back

Metals typically become cations by losing electrons.

Front

What charge does fluorine typically have when it forms an ion?

Back

Fluorine typically has a slight negative charge when it forms an ion.

Front

What are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules.

Front

Which molecule has only London dispersion forces?

Back

I2 (iodine) has only London dispersion forces.

Front

What is a covalent network crystal?

Back

A covalent network crystal is a solid where atoms are bonded by covalent bonds in a continuous network.

Front

Give an example of a covalent network crystal.

Back

SiO2 (silicon dioxide) is an example of a covalent network crystal.

Front

What is the difference between intermolecular and intramolecular forces?

Back

Intermolecular forces are forces between molecules, while intramolecular forces are forces within a molecule.

Front

What is a cation?

Back

A cation is a positively charged ion formed when an atom loses one or more electrons.

Front

What is a dipole-dipole interaction?

Back

A dipole-dipole interaction is an attractive force between the positive end of one polar molecule and the negative end of another.
