Periodic Properties of Metals

These flashcards cover key terms and concepts related to the periodic properties of metals and laboratory procedures.

Flame Test

A method used to identify the presence of certain metal ions based on the characteristic colors they produce when heated.

Ionization Energy

The energy required to remove an electron from an atom or ion, affecting how metals behave in reactions.

Alkali Metals

Elements in Group 1 of the periodic table (Li, Na, K) that are highly reactive and do not precipitate.

Alkaline-earth Metals

Elements in Group 2 of the periodic table (Mg, Ca, Sr, Ba) that exhibit different solubility trends in reactions with sulfate and carbonate.

Excited State

A state of an atom where electrons have absorbed energy and moved to a higher energy level, resulting in the emission of light when they return to a lower state.

Precipitation Reaction

A chemical reaction that occurs when two solutions combine to form an insoluble compound, leading to the formation of a solid.

Atomic Spectra

The spectrum of frequencies of electromagnetic radiation emitted or absorbed during transitions of electrons within atoms.

Bunsen Burner

A common laboratory device used to produce a single open gas flame, used for heating, sterilization, or combustion.

Solubility Trends

Patterns observed in how soluble different compounds are in water, especially as you move down a group in the periodic table.

Hazardous Materials

Substances that pose a potential risk to health, safety, or the environment, such as H2SO4 which is a contact hazard.
