Will we run out of elements in 100 years?
« on: 23/08/2010 21:19:44 »
In 100 years time, what will the periodic table look like. Which elements will have become extinct? Will elements run out?

No... there is no possibility of "elements running out".

Elements can react with each other to form compounds, for example iron rusts to make iron oxide, which is composed of iron and oxygen. However, in order to get hold of (most) elements, we have to extract them chemically from the compounds they occur in naturally - and the iron ore which we got the iron from in the first place, is just a form of iron oxide. It took energy to produce iron first time out, if we want to get the iron back again it'll take more energy.

I suspect what you're talking about is actually resource crises, shortages of elements (or compounds) in forms from which they can easily and efficiently be extracted. In which case, yeah, odds are copper and platinum are both going to get more difficult to get hold of.. but the stuff we've already used hasn't ceased to exist, it's still out there in computers and fuel cells and catalytic converters and phone cables, but we'll have to learn to be more efficient in what we use it for (and probably to mine our own rubbish dumps).

No Helium,

Incredible as it may seem, the second most abundant element in the universe after hydrogen will soon be unavailable for Earth. Helium gas represents 8 percent of the total mass observed in the universe, but the reserves of the largest helium mining facility located in Texas are predicted to deplete in about eight years.

If anything there are likely to be a few more (synthetic) elements in the periodic table by then.

Very interesting folks. I suspect there may be more changes than this. Anyone else got some ideas?

Bored C, can you elaborate on the synthetic elements?

There are a few elements that are so unstable that any made by the big bang have decayed. On the other hand you can make them with a nuclear reactor or an accelerator. Most of them are transuranic (heavier than uranium).
http://en.wikipedia.org/wiki/Transuranium_element

The others are technetium and promethium (and a few oddities like tritium).

The heavy ones are difficult to make but, as technology (and bloodymindedness) improve, we may make a few more in the next century or so.

I guess they are quite expensive to make at the moment?

As we try to be greener eg. making solar pannels, I guess minerals used to make this kit will become rare too?

They use a lot of silicon. I don't think we will ever run out of that.

The one in my kettle blew up the other day, so I went round to the Hotpoint store to get a replacement, but they were out of their elements.

Flint, the world purest form of silica is scarce.
Can anyone send me flint please?

I need pure silica and it apparently is scarce. Once exported from UK but now too expensive due to rarity.

I think somebody is winding you up. There's more silica in the Earth's crust than anything else  [:D]

There are various forms of silica. Fused quartz is pure amorphous silica
I am looking for flint, Variant: chert. Very hard dense nodules of microcrystalline quartz and chalcedony found in chalk and limestone.

I would be very interested in finding how to get it. Last I saw it was $100 per ounce because of its rearity I've been told.

Unavalable in Aust. It was previously exported here by UK

What!!! The stuff is abundant. Go to the chalk of the South Downs, or the white cliffs of Dover. There are nodules and continuous beds of the stuff stretching for miles along and into the cliffs. There are beaches that consist of nothing but chert pebbles. Whoever is charging $100 an ounce is jerking your chain.

I can buy flint arrowheads from the neolithic era on eBay for less than $100 an ounce.

I seem to remember it was a common building material in some parts of England too!

I'm sure we could organize a shipment from the UK at a super discounted price of $50 per ounce*.

So I would say elements are not so scarce it just depends on where you look.

In that regard have a look at the Apex chert, in the Pilbara craton in Western Australia. Homne grown is best. [;)]

Ok folks we have lost the plot again so here is an article to get your teeth into.
http://theeconomiccollapseblog.com/archives/rare-earth-elements-the-world-is-rapidly-running-out-and-china-has-most-of-the-remaining-supply


and it appears Uk has the most purest form of silica, flint, and Australia has the most steel, possibly owned by Chinese.
