Why does the Periodic Table have that separated part (lanthanides and actinides) at the bottom?
zepelin [54]

In the periodic table the lanthanoid and the actinides are place separately at the bottom because of their electronic configuration and their properties compared to the other elements.

The  the lanthanoid and the actinides are place separately at the bottom in the periodic table due to their electronic configuration and the properties. and to make the periodic table more convenient . if we place the f block elements that is he lanthanoid and the actinides then the size of the periodic table will increase. the f block elements are called as the inner transition element.

Thus , to make the periodic table more convenient and to group the elements in the block the the lanthanoid and the actinides are place separately at the bottom.

Scientists saw how well people responded to animals and imagined ___________ that these interactions might be helpful in some ty
sukhopar [10]

For most of the last 50 years, technology knew its place. We all spent a lot of time with technology—we drove to work, flew on airplanes, used telephones and computers, and cooked with microwaves. But even five years ago, technology seemed external, a servant. These days, what’s so striking is not only technology’s ubiquity but also its intimacy.

On the Internet, people create imaginary identities in virtual worlds and spend hours playing out parallel lives. Children bond with artificial pets that ask for their care and affection. A new generation contemplates a life of wearable computing, finding it natural to think of their eyeglasses as screen monitors, their bodies as elements of cyborg selves. Filmmakers reflect our anxieties about these developments, present and imminent. In Wim Wenders’s Until the End of the World, human beings become addicted to a technology that shows video images of their dreams. In The Matrix, the Wachowski brothers paint a future in which people are plugged into a virtual reality game. In Steven Spielberg’s AI: Artificial Intelligence, a woman struggles with her feelings for David, a robot child who has been programmed to love her.

Today, we are not yet faced with humanoid robots that demand our affection or with parallel universes as developed as the Matrix. Yet we’re increasingly preoccupied with the virtual realities we now experience. People in chat rooms blur the boundaries between their on-line and off-line lives, and there is every indication that the future will include robots that seem to express feelings and moods. What will it mean to people when their primary daily companion is a robotic dog? Or to a hospital patient when her health care attendant is built in the form of a robot nurse? Both as consumers and as businesspeople, we need to take a closer look at the psychological effects of the technologies we’re using today and of the innovations just around the corner.

Indeed, the smartest people in the field of technology are already doing just that. MIT and Cal Tech, providers of much of the intellectual capital for today’s high-tech business, have been turning to research that examines what technology does to us as well as what it does for us. To probe these questions further, HBR senior editor Diane L. Coutu met with Sherry Turkle, the Abby Rockefeller Mauzé Professor in the Program in Science, Technology, and Society at MIT. Turkle is widely considered one of the most distinguished scholars in the area of how technology influences human identity.

Few people are as well qualified as Turkle to understand what happens when mind meets machine. Trained as a sociologist and psychologist, she has spent more than 20 years closely observing how people interact with and relate to computers and other high-tech products. The author of two groundbreaking books on people’s relationship to computers—The Second Self: Computers and the Human Spirit and Life on the Screen: Identity in the Age of the Internet—Turkle is currently working on the third book, with the working title Intimate Machines, in what she calls her “computational trilogy.” At her home in Boston, she spoke with Coutu about the psychological dynamics between people and technology in an age when technology is increasingly redefining what it means to be human.

You’re at the frontier of research being done on computers and their effects on society. What has changed in the past few decades?

To be in computing in 1980, you had to be a computer scientist. But if you’re an architect now, you’re in computing. Physicians are in computing. Businesspeople are certainly in computing. In a way, we’re all in computing; that’s just inevitable. And this means that the power of the computer—with its gifts of simulation and visualization—to change our habits of thought extends across the culture.

Describe what does happen to the electrons when metal atoms are bonded together.
tankabanditka [31]

Answer: In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions. Metals are shiny.

Explanation: Hope this helped!

From the relative rates of effusion of ²³⁵UF₆ and ²³⁸UF₆ , find the number of steps needed to produce a sample of the enriched f
Dafna11 [192]

The number of steps required to manufacture a sample of the 3.0 mole%  ²³⁵U enriched fuel used in many nuclear reactors from the relative rates of effusion of ²³⁵UF₆ and ²³⁸UF₆. ²³⁵U occurs naturally in an abundance of 0.72% are :  mining, milling, conversion, enrichment, fuel fabrication and electricity generation.

<h3>What is Uranium abundance ? </h3>
  • The majority of the 500 commercial nuclear power reactors that are currently in operation or being built across the world need their fuel to be enriched in the U-235 isotope.
  • This enrichment is done commercially using centrifuges filled with gaseous uranium.
  • A laser-excitation-based method is being developed in Australia.
  • Uranium oxide needs to be changed into a fluoride before enrichment so that it can be treated as a gas at low temperature.
  • Uranium enrichment is a delicate technology from the perspective of non-proliferation and needs to be subject to strict international regulation. The capacity for world enrichment is vastly overbuilt.

The two isotopes of uranium that are most commonly found in nature are U-235 and U-238. The 'fission' or breaking of the U-235 atoms, which releases energy in the form of heat, is how nuclear reactors generate energy. The primary fissile isotope of uranium is U-235.

The U-235 isotope makes up 0.7% of naturally occurring uranium. The U-238 isotope, which has a small direct contribution to the fission process, makes up the majority of the remaining 99.3%. (though it does so indirectly by the formation of fissile isotopes of plutonium). A physical procedure called isotope separation is used to concentrate (or "enrich") one isotope in comparison to others. The majority of reactors are light water reactors (of the PWR and BWR kinds) and need their fuel to have uranium enriched by 0.7% to 3-5% U-235.

There is some interest in increasing the level of enrichment to around 7%, and even over 20% for particular special power reactor fuels, as high-assay LEU (HALEU).

Although uranium-235 and uranium-238 are chemically identical, they have different physical characteristics, most notably mass. The U-235 atom has an atomic mass of 235 units due to its 92 protons and 143 neutrons in its nucleus. The U-238 nucleus has 146 neutrons—three more than the U-235 nucleus—in addition to its 92 protons, giving it a mass of 238 units.

The isotopes may be separated due to the mass difference between U-235 and U-238, which also makes it possible to "enrich" or raise the proportion of U-235. This slight mass difference is used, directly or indirectly, in all current and historical enrichment procedures.

Some reactors employ naturally occurring uranium as its fuel, such as the British Magnox and Canadian Candu reactors. (By contrast, to manufacture at least 90% U-235, uranium needed for nuclear bombs would need to be enriched in facilities created just for that purpose.)

Uranium oxide from the mine is first transformed into uranium hexafluoride in a separate conversion plant because enrichment operations need the metal to be in a gaseous state at a low temperature.
