Group 1A/B

Alkali Metals

H, Li, Na, K, Rb, Cs, Fr, NH4+; most reactive group, seldom found free in nature.

Valence of Alkali Metals

+1

Hydrogen (H2)

Lightest element with a molecular weight of 1 g/mol; forms water when burned with O2.

Deuterium (D2O)

Heavy isotope of hydrogen, used in 'heavy water' and as a solvent in NMR Spectroscopy.

Lithium (Li)

Lightest metal, used as a diuretic and mood stabilizer for bipolar disorders.

Sodium (Na)

Cation of choice for organic medicinal use.

Potassium (K)

Soluble salts; used as a diuretic and muscle contractant.

Copper (Cu)

Cuprum; malleable metal that undergoes disproportionation and is involved in respiratory pigments.

Gold (Au)

Aurum; known as the king of all metals and can be dissolved by aqua regia.

Colloidal silver protein (Collargol)

General germicide with a silver content of 10-22%.

Ammonia (NH3)

Respiratory stimulant with a pungent odor, used in dilute and strong ammonia solutions.

Coinage Metals

Metals that occur free or in complexes; examples include Cu, Ag, Au.

Hydrogen Production Method

Lane & Messerschmidt Process, yielding 99% pure H2O.

Lithium Carbonate

Used widely for the prophylaxis and treatment of bipolar disorder.

Ammonium (NH4+)

Weak base that has pharmacological uses such as a diuretic and buffer.

Cesium (Cs)

First element discovered using a spectroscope, has a spectral line that appears blue.

Silvers Antiseptic Use

Mild silver protein (Argyrol) used as an antiseptic for the eyes.

Aurinofin (Ridaura)

A gold preparation used in the treatment of rheumatoid arthritis.

Tritium

Radioactive isotope of hydrogen.

Haber Process

Industrial method for producing ammonia from nitrogen and hydrogen at high pressures.

Rubidium (Rb)

A metal with a red spectral line, discovered in 1861.

Francium (Fr)

A hypothetical alkali metal, named after France.

Spirit of Hartshorn

Strong ammonia solution containing 27-31% NH3.

Selenium-Based Acid

H2SeO4; only acid that can dissolve gold.

Non-Pharmacological Use of Lithium

Used as a heat exchanger in air-conditioning.

Aurothioglucose (Solganal)

A gold preparation for treatment of rheumatoid arthritis and gout.
