coinage metals / group 2B / 11

Coinage metals Grou 1B/11

copper, gold, silver, roentgenium (sa periodic table lng)

Coinage metals

"• d-block metals • Noble metals • Ornaments and coinage • Conductors of electricity (Ag, Cu, Au) • Highly malleable • Highly ductile"

d block metals

d orbitals are completely filled

why are coinage metals are called noble metals?

because they are less reactive compound compared to other metals

why are coinage metals are called ornaments and coinage?

coinage because they are used to make coins

highly malleable

can be flattend into sheets and converted into different shapes examples are jewelry

highly ductile

they can be cut into wires by stretching

Copper (Cu)

"Cuprum - Cypress.; Essential trace element - utilization of iron • Hemocyanin - respiratory pigment (invertebrae) • Cofactor in cytochrome oxidase"

Essential trace element

- "utilization of iron" so we can use iron properly. needed in the body in very small amount

Cofactor in cytochrome oxidase

located in the mitochondria. essential in production of ATP. For the enzyme to function properly it needs a few copper.

CuCl2H4O2

copper chloride dihydrate. Use: injection added to TPN

Total parenteral nutrition (TPN)

consists of essential nutrients. GIven to severly malnourished and ill patients and needs other ways to administer food injected through IV line

CuSO4 + 5H2O

"cupric sulfate penta hydrate (blue vitriol, blue stone, salzburg)"

64 Cu isotope

To diagnose excess copper in the body (Wilson's disease)

CuSO4

"Copper II sulfate Fehling's and Benedict's, Barfoed's sol'n used to detect specific functional group in organic compunds. ;Uses: fungicide, insecticides, algicides"

Silver (Ag)

Argentum. Best conductor of electricity and heat

AgNO3

silver nitrate (lunar caustic) ;Uses: germicide, warts

1% AgNO3

"Silver nitrate Use: Antibacterial Eye drops - for newborn babies (normal delivery) because they pass by the vaginal canal which is full of bacteria this will prevent babies from getting blind"

Toughened AgNO3

styptic - can be applies to small wound and to stop bleeding

Silver sulfadiazine

germicide on burn wounds. Silver dressings on wounds Ex tegaderm Algivate put on wounds so it will heal faster and prevent infection

Gold (Au)

"Aurum - Shinning Dawn. King of all metal • ductile & malleable"

why is gold considered as King of all metal?

because it doesn't rust and it's shiny.

Gold sodium thiomalate

Rheumatoid Arthritis (intra-muscular)

Auranofin

Rheumatoid Arthritis (oral)

Aurothioglucose

Rheumatoid Arthritis (intra-muscular)

198 Au isotope

malignancies/cancer. Release radiation can be used to kill cells like cancer cells/tumor. Cons: radiation therapy and chemotherapy kills both good and bad cells not targeted.
