So deuterium has one neutron and since neutrons have mass, deuterium has more mass than protium. So isotopes have different masses because they differ in terms of number of neutrons. Notice though, that they h

There are an uncountable number of other ways that humanity’s dive into nuclear chemistry has impacted the lives of people across the world, from medical imaging equipment to smoke detectors and even, surprisingly, to some of the food that we eat. After World War 2, there was a push to ...
virtue of their size and mass • 4. Chemical compounds are formed by the union of two or more atoms of different elements • 5. Atoms combine to form compounds in whole number ratios (1:2 or 2:2, etc] • 6. Atoms of two elements may combine in ...
obliteration of the city of Tokyo in March of 1945 using petroleum and biomass (nitroglycerine, palmitic acid and nitrocellulose) derived weapons of mass destruction, nuclear war was no longer merely possible: It had become inevitable. We know that nuclear has always been possible since nuclear ...
Lightbridge’s metal alloy fuel is positioned to be a non-disruptive improvement for nuclear power production that can be adapted to fit into a number of existing supply chains and established regulatory review processes. The newly developed individual fuel pins are substantially different from the ex...
protons and neutrons center of an atom is a nucleus subatomic particle with the smallest mass electron an atom that is nuetral has the same number of protons and elctrons Isotopes are an element with the same number of protons but a different number of nuetrons. ...
'I've heard about these waste-containers' said Tim, 'but I thought they'd all been collected and the stuff in them buried somewhere on the Moon.' 'Not this one, apparently. But it soon will be when we report it. Good work, Malcolm! You've done your bit to make space safer!' I...
We do not yet know what the asteroids are made of. Many of them are extremely dark in color and have optical characteristics resembling those of a kind of meteorite called carbonaceous chondrite. The carbonaceous chondrites are made of stuff rather like terrestrial soil, containing a fair fractio...
When Chalk River was being refurbished in Canada, there was a world shortage of these precious isotopes and Tc 99 from the rods of commercial nuclear reactors could have been a source of relief. Medical isotopes could also be produced from commercial reactors. DV82XL says: September 30, 2011...
