61⟩ Tell me what is the basic material or fuel that makes nuclear energy possible?
It's always uranium. It's the fission of uranium.

It's always uranium. It's the fission of uranium.
Molality is the number of solute that is present in 1 kg of a solvent.
This principle states that an orbital can have maximum two electrons and these must have opposite spins.
Graphite rod is used in nuclear reactor to convert fast moving neutrons into thermal neutrons.
No. Of course they don't. And that, I think, is somewhat understandable. But why the anti-nuclear folks, who say such extreme things that on the face of it one would question, even one who knew nothing about the subject, why they would have credibility, that does puzzle me.
A valency is a property of a groups or atoms, equal to the number of atoms of hydrogen that the group or atom could combine with or displace it in forming compounds.
A system that exchanges only energy and not matter with the surrounding is said to be a closed system. For example: A reaction taking place in a closed metallic vessel.
A buffer is an aqueous solution which has highly stable pH. It is a blend of a weak acid and its conjugate base or vice versa. On adding small amount of base or acid to buffer, its pH hardly changes.
You have to eat it in order to harm yourself with it. It is radioactive, naturally. Radioactive, but much less so than radium, for example, which is scattered again all over the earth's crust. So it's not a very frightening material.
According to Avogadro’s law, at same temperature and pressure equal volume of gases contains the same number or molecules regardless of the chemical nature and physical properties.
Avogadro’s number = 6.023 X 10 (-23)
Electron pairing in p, d and f orbitals cannot occur until each orbital of a given subshell contains one electron or is singly occupied. This happens because electrons being identical in charge repel each other when present at the same orbital.
That's as bad an accident as you can get from a nuclear plant. And worse than any accident in a modern nuclear plant could possibly be. The point is that that reactor was on fire for days and days and days, with radioactive material going up into the air. But it was the crudest kind of reactor, which the Soviets thankfully have stopped building.
Aliquot : It is a measured sub-volume of original sample
Diluent: Material with which sample is diluted
Plutonium is, in fact, a metal very like uranium. If you hold it [in] your hand (and I've held tons of it my hand, a pound or two at a time), it's heavy, like lead. It's toxic, like lead or arsenic, but not much more so.
In a molecule when hydrogen atom is less than the ratio of carbon atom, then such molecules are referred as an organic molecule.
Plutonium is simply a material that is very like uranium, being produced from uranium. It's produced by the absorption of a neutron in uranium, and you get this new metal which has been called plutonium. Its properties are not dissimilar to one of the isotopes of one of the kinds of uranium that exist in the earth's crust. It is fissionable, like the fissionable isotope of uranium. That is to say, you could make a reactor out of it, out of plutonium.
Well, the special property is that if it is bombarded with neutrons, then the uranium nucleus will split in two, and with that a large amount of energy is released in the form of heat. And this is called fission.
It is denoted by l. Through this quantum number we get to know the number of sub-shells present in the main shell. It also gives information about the shapes of various shells present within the same principal shell and also about the relative energies associated with these sub-shells.
Titration is a process to determine the molarity of a base or an acid. In this process a reaction is carried out between the known volumes of a solution with a known concentration, against the known volume of a solution with an unknown concentration.
