How many neutrons are in the isotope uranium-238?
Uranium, atomic number 92, has several isotopes, and 238U is just one of them. Remember that a nucleon is one of the particles that make up the nucleus of an atom, and that means a proton or a neutron. In the case of this isotope of uranium, it has the 92 protons we'd expect for uranium, and it has 146 neutrons in its nucleus along with those protons. That's 238 necleons in the nucleus if 238U. Wikipedia has more information on uranium and on the nucleon, and links are provided.
What physical and chemical properties would you expect to find in two different samples of a pure substance?
Two different samples of a pure substance would have the same physical properties, such as color, melting point, boiling point, and density. Their chemical properties, like reactivity and ability to form specific compounds, would also be identical. Variations in the samples' properties could indicate impurities present.
How much uranium is left?
There are thought to be about 5 million tons of the grade of ore being mined now, typically 0.1 to 0.25 percent uranium oxide. So that represents 5000 to 12500 tons of uranium. This will keep the industry going for some years yet. Eventually lower grade ores will have to be mined which will be more expensive, but there is no reason to expect a shortage.
How much does uranium 237 cost per gram in inr?
Well, based on recent studies... In terms of power production, 1 kilogram of uranium-235 is equivalent to 2.7 million kilograms of coal. With those numbers in mind, I would expect 1 gram of uranium-237 to cost somewhere between $300-$600 million. There are many other factors involved but I do know that I need to be in the business of selling uranium because unemployment isn't paying my bills.
Why would you expect the climate of a large area to be similar to that of the area surrounding it?
Large cities=large groups of people=hotter climates
Would you expect neodymium and uranium to similar properties?
Uranium and neodymium are very different chemical elements.
Where on the periodic table would you expect to find elements with similar properties and chemical characteristics?
Elements in a same group have same number of valence electrons and hence similar physical and chemical properties.
What pair of elements do you expect to be most similar?
I expect elements with similar properties in the periodic table to be most similar. For example, elements in the same group or period tend to have similar chemical characteristics due to their similar electron configurations.
What color does uranium burn in a flame test?
Uranium cannot be tested with the flame test. Uranium hasn't been tested with the flame test. If the temperature in a nuke were similar though, you could expect a red or yellowish burn. With the bead test, it is a greenish.
How may protons would you expect to find in an atom of uranium'?
92 protons.
What element would have properties most similar to the new element?
The newest officially discovered elements are Ununquadiumand Ununhexium so, we'll focus on those.Ununquadium will be part of the Carbon series, so we would expect it to have properties similar to those elements (e.g. 4 electrons in the outer shell). The closest relation to it in that group would be Lead.Ununhexium will be part of the Oxygen series, so, again, we would expect it to have properties similar to those elements (e.g. 6 electrons in the outer shell). The closest relation to it in that group would be Polonium, which is also the first radioactive element.
What elements would you expect to be similar to technetium?
Rhenium is similar to technetium.
Which element would you expect behave the most like carbon?
Ge Germanium
Which elementswould you expect to be similar to technetium?
Technetium is chemically similar to manganese and rhenium.
How similar might you expect the chemical properties of gallium and indium to be?
Gallium and indium are both in the same group of the periodic table (Group 13), so they have similar chemical properties. Both elements are soft metals with low melting points and are often used in electronic applications due to their unique properties. However, gallium is more reactive than indium and has a lower melting point.
A compound known as cubic boron nitride has a structure similar to that of a diamond what properties would you expect it to have?
Cubic boron nitride would be expected to have properties similar to diamond, such as extreme hardness, high thermal conductivity, and excellent resistance to chemical corrosion. It is commonly used in cutting tools and abrasives due to its hardness and wear resistance.
Would you expect nitrogen and argon to have similar chemical properties?
No, nitrogen and argon have different chemical properties. Nitrogen is a reactive diatomic nonmetal, while argon is a noble gas known for its inertness. Nitrogen tends to form compounds, while argon is largely unreactive.
