Chem 2nd Half

Front

An ideal gas model is used to explain the behavior of gases.

Back

A real gas is most like an ideal gas at low temperature and high pressure.

Front

Kinetic Molecular Theory (KMT) for an ideal gas

Back

States that all gas particles are in random motion, have no forces of attraction, have negligible volume, and have collisions with no net loss of energy.

Front

Kinetic energy

Back

Energy of motion.

Front

Heat transfer

Back

Heat is a transfer of energy from a body of higher temperature to a body of lower temperature.

Front

The atomic mass is the sum of protons and neutrons.

Back

The mass number on the periodic table is a weighted average of isotopes.

Front

Isotopes of an element have the same number of protons.

Back

Isotopes differ in the number of neutrons.

Front

Elements can be classified by their properties and location on the Periodic Table.

Back

Classifications include metals, non-metals, metalloids, and noble gases.

Front

Elements may be differentiated by their physical properties.

Back

Examples include density, conductivity, malleability, hardness, ductility, solubility.

Front

Elements are arranged into periods and groups.

Back

This arrangement helps identify properties and behaviors.

Front

The succession of elements in a group shows characteristic trends.

Back

As you progress down a group, atomic radius increases.
