WTungsten / Symbol

tungsten (W), also called wolfram, chemical element, an exceptionally strong refractory metal of Group 6 (VIb) of the periodic table, used in steels to increase hardness and strength and in lamp filaments.

Which element is not a Chalcogen?

In group 16, the oxygen, sulphur, selenium are called chalcogens (ore-forming) while polonium being radioactive forms a less number of compounds and is not considered as chalcogens.

Is thorium 232 fissile?

Thorium (Th-232) is not itself fissile and so is not directly usable in a thermal neutron reactor. However, it is ‘fertile’ and upon absorbing a neutron will transmute to uranium-233 (U-233)a, which is an excellent fissile fuel materialb. In this regard it is similar to uranium-238 (which transmutes to plutonium-239).

What is uranium-233?

Uranium-233 is a fissile isotope of uranium that is bred from thorium-232 as part of the thorium fuel cycle.

What is uranium 233 used for in everyday life?

Further information. Uses for uranium-233 include the production of the medical isotopes actinium-225 and bismuth-213 which are among its daughters, low-mass nuclear reactors for space travel applications, use as an isotopic tracer, nuclear weapons research, and reactor fuel research including the thorium fuel cycle.

What is Thor thorium 233?

Thorium, from which 233 U is bred, is roughly three to four times more abundant in the earth’s crust than uranium. The decay chain of 233 U itself is part of the neptunium series, the decay chain of its grandparent 237 Np.

What is atomic mass of an element?

The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope. (Atomic mass is also referred
