Gold and Silver Trivia
Chemical Symbol Au, Atomic Number 79, Melting Point 1,064°C
1 litre of gold weighs 19.3 kilograms. 1 litre of water weighs 1 kilogram.
A cubic foot (about the size of a milk crate) weighs roughly 500kg.
It is the 75th most abundant element on earth.
Gold does not rust or tarnish and is non-toxic.
Approximately 168,000 tonnes of gold have even been mined. That is a cube with sides of 19 metres long.
There are about 24.75 grams of gold for every person on earth.
Fine gold is so malleable that it can be beaten down to a thickness of 0.0001112 mm into translucent gold leaf. 31 grams of it will cover about 16 square metres!
Gold is an excellent conductor of electricity. (3rd best behind silver and copper.)
Gold is the only metal that can be beaten thin enough to be seen through [as on the visors of astronaut’s helmets].
Gold is almost chemically inert and can not be dissolved by any single acid.
The largest gold nugget known to be found was called ‘The Welcome Stranger’. Found in Dunolly, Victoria, Australia, it weighed a massive 70 kilograms. Today it would be worth around $3.15 million Australian dollars.
Chemical Symbol Ag, Atomic Number 47, Melting Point 962°C
1 litre of silver weighs 10.5 kilograms.
A cubic foot (about the size of a milk crate) weighs roughly 284 kilograms.
Sterling Silver is 92.5% silver and 7.5% copper by weight.
Silver was widely used in photography (films and papers) before the introduction of digital cameras.
In the early 1900s people would put silver coins in milk bottles to prolong the milk’s freshness.
In the Gospels, Jesus’ disciple Judas Iscariot is infamous for having taken a bribe of thirty coins of silver from religious leaders in Jerusalem to turn Jesus Christ over to the Romans.
Silver itself is not toxic but most silver salts are, and some may be carcinogenic.
A chain made of Sterling Silver weighs about 90% of an identical chain made of 9ct gold.
It is the most electrically conductive metal.
The largest silver nugget in the world weighing 933 kilograms was more than 93 percent pure silver. Today it would be worth around $600,000 Australian dollars. Hmmm, rather have the 70 kilos of gold, and a lot easier to carry!
