Thorium is a naturally occurring, radioactive substance. In the environment, thorium exists in combination with other minerals, such as silica. Small amounts of thorium are present in all rocks, soil, water, plants, and animals.Soil contains an average of about 6 parts of thorium per million parts of soil (6 ppm). More than 99% of natural thorium exists in the form of thorium-232.
Physical Characteristics. Thallium is a greyish color post-transition metal. It is soft and can be cut with a knife. Thallium is malleable. Freshly isolated thallium looks like tin and is readily discolored (becomes bluish-grey) and loses it shine when exposed to air. It is quite dense and have a density of 11.85 g/cm 3.

Thorium is much more abundant in nature than uranium. Thorium can be used as a nuclear fuel through breeding to uranium-233 (U-233). When this thorium fuel cycle is used, much less plutonium and other transuranic elements are produced, compared with uranium fuel cycles. Several thorium-fuelled reactor concepts are under consideration.
Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.
Thorium is a naturally-occurring, radioactive metal. Small amounts of thorium are present in all rocks, soil, above-ground and underground water, plants, and animals. Thorium is an element used mainly as a nuclear power source and in magnesium alloys, …
There are many possible fill gases (solids) for electric discharge lamps, including mercury, xenon, argon and sodium, and halides of tin, sodium, indium, thallium, lithium, thorium, thulium, holmium and dysprosium (Speros and Caldwell 1972). Currently, only the high-pressure sodium (HPS) lamp requires a ceramic envelope, but this situation may ...

Thorium belongs to actinide series in the periodic table. It makes a face centred cubic crystal structure at room temperature. Thorium is very ductile in pure form and can be forged easily. It is malleable and its bulk modulus is same as that of tin. Thorium is less dense when compared to its nearby elements, for instance, uranium.

Thallium (Tl) with an atomic number of 81 is found in the periodic table with the symbol. Thallium is not freely found in nature. It is a soft grey post- transition metal. It resembles tin when isolated but when exposed to air it may discolour. There are around eighty-one electrons present in the atom of thallium with an electronic ...

Element reactions. This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of thorium. For each compound, a formal oxidation number for thorium is given, but the usefulness of this number is limited for p -block elements in particular.
Thorium-232 will absorb slow neutrons to produce uranium-233, which has somewhat similar properties to uranium-235 (used in conventional pressurized water reactors). India is especially pushing this technology, since they have 4 times as much thorium as uranium in reserves. Their first thorium research reactor went critical in 1996.
Thorium may be three times more abundant on Earth than uranium, it is difficult to estimate, and can also be used in nuclear reactors. In addition, thorium and uranium deposits do not necessarily occur at the same places, thus countries with large potential uranium resources may well have very little thorium …

Thallium enters the environment primarily from coal-burning and smelting, in which it is a trace contaminant of the raw materials. It stays in the air, water, and soil for a long time and is not broken down. Some thallium compounds are removed from the atmosphere in rain and snow. It's absorbed by plants and enters the food chain.

But the real reason we use uranium over thorium is a result of wartime politics. Cold War-era governments (including ours) backed uranium-based reactors because they produced plutonium — handy for making nuclear weapons. With some modifications, today's commercial nuclear reactors could switch to thorium-based fuels, but at great cost.

Thallium leaves blood plasma rapidly and is readily transported between body organs and tissues. It can be deposited in kidneys, pancreas, spleen, liver, lungs, muscles, neurons and brain. Blood is not a reliable indicator of thallium status. Symptoms of thallium contamination are often delayed. Early signs of chronic, low-level contamination ...
