Definition: Not the best or most suitable; not meeting the ideal standard.

Example: The nonideal conditions made it difficult to complete the experiment successfully.

Definition: Describing a substance that does not have ionic properties or is not affected by ions.

Example: The nonionic surfactant is safe for use in sensitive applications.

Definition: Describing a type of radiation that does not have enough energy to remove tightly bound electrons from atoms or molecules, meaning it does not cause ionization.

Example: Nonionizing radiation, such as radio waves, is generally considered safe for human exposure.

Definition: Not flat or even; having an uneven surface or height.

Example: The ground was nonlevel, making it difficult to set up the tent properly.

Definition: A substance that is not in a liquid state, such as a solid or gas.

Example: Sand is a nonliquid material that can be used in construction.

Definition: Not giving off light or brightness; dark.

Example: The nonluminous surface of the moon reflects sunlight but does not emit its own light.

Definition: Not able to be attracted by a magnet or not influenced by magnetic fields.

Example: The material used for the casing is nonmagnetic, ensuring it won't interfere with the device's operation.

Definition: Not able to be shaped or bent easily without breaking.

Example: The metal is nonmalleable, meaning it cannot be easily formed into different shapes.

Definition: A type of element that does not have the properties of metals, often found in gases or brittle solids.

Example: Oxygen is a common nonmetal that is essential for life.

Definition: Describing a substance that is not a metal and does not have metallic properties.

Example: Sulfur is a nonmetallic element that is essential for life.
