Key terms & definitions

A chemical test in which iodine turns blue-black if starch is present and remains yellow-brown if it is not detected.

The coordination of communication between software and input/output devices by the operating system.

An atom or group of atoms with an overall electrical charge because it has gained or lost electrons.

An atom or group of atoms with an overall electrical charge because it has gained or lost electrons.

An atom or group of atoms with an overall electrical charge.

The overall electrical charge produced by the difference between the numbers of protons and electrons.

A region of Greek cities on the western coast of Asia Minor, in modern-day Turkey.

The uprising of Ionian Greek cities against Persian rule, beginning in 499 BC and defeated in 494 BC.

The strong electrostatic attraction between oppositely charged ions.

The strong electrostatic force of attraction between oppositely charged ions.

A strong electrostatic attraction between oppositely charged ions.

The strong electrostatic attraction between oppositely charged ions, acting in all directions throughout an ionic lattice.

The electrical property of an ion, written as a superscript with a magnitude and a positive or negative sign, such as $2+$ or $1-$.

A compound made from oppositely charged ions, usually positive metal ions and negative non-metal ions.

A compound consisting of positive and negative ions held together in a giant structure by strong electrostatic attraction.

A chemical equation showing only the ions that take part in the reaction, with atoms and electrical charge balanced.

An equation showing only the particles involved in the chemical change, with unchanged spectator ions omitted.

A continuous band of decoration, unlike a Doric frieze divided into metopes and triglyphs.

A regular, repeating three-dimensional arrangement of positive and negative ions.

A substance made from oppositely charged ions held in a giant lattice by strong electrostatic attractions.

The formation of ions from neutral particles when a substance is dissolved or reacts.

The process in which one or more electrons are removed from an atom, leaving a positively charged ion.

The production of charged particles called ions. Nuclear radiation can ionise atoms by knocking electrons out of them.

A radiation's ability to remove electrons from atoms and form ions as it travels through matter.

Radiation with enough energy to remove electrons from atoms, forming ions.

Radiation with enough energy to remove electrons from atoms, forming ions. X-rays and gamma rays are ionising radiation.

A regular arrangement of ions in a metal. The ions vibrate about fixed positions while electrons can move through the metal.

The smallest whole-number ratio of each type of ion in an ionic compound.

Charged particles, such as sodium ions, whose concentrations in body fluids affect the movement of water.

Internet Protocol: a protocol that provides addressing and routing so packets can be directed towards their destination across networks.
