Effects of Alkali Metals and Oxide Reactions

These flashcards encompass key vocabulary related to the chemical reactions and properties of alkali metals as discussed during the lecture.

Oxidation

The process by which an element loses electrons, often reacting with oxygen.

Metal Oxide

A compound formed when a metal reacts with oxygen, often leading to rusting in alkali metals.

Peroxide

A type of oxide where oxygen has an oxidation state of -1, represented as MO₂ for alkali metals.

Superoxide

An oxide containing the superoxide ion, where oxygen has an oxidation state of -1/2.

Reducing Agent

A substance that donates electrons in a chemical reaction, effectively reducing another substance.

Oxidizing Agent

A substance that accepts electrons in a chemical reaction, causing oxidation of another substance.

Alkali Metal Oxides

Oxides of alkali metals that typically dissolve in water to form strong bases.

Chemical Reactivity

The tendency of a substance to participate in a chemical reaction, often influenced by its metallic character.

Characteristic Spectrum

The unique emission of light (specific wavelengths) from an element due to electron transitions.

Hydroxide

A compound formed from the reaction of an alkali metal with water, typically resulting in OH⁻ ions.
