Are ferro magnetic materials insulators?

Not necessarily. Ferromagnetic materials can be conductors, semiconductors, or insulators depending on their specific composition and structure. Magnetic properties and electrical conductivity are independent characteristics of a material.

When do photons behave more like a wave?

Photons behave more like a wave when they exhibit phenomena such as interference and diffraction, which are characteristics of wave behavior. This is evident in experiments like the double-slit experiment where photons create an interference pattern when passed through two slits.

What atom has 14 proton 1 a S 2 b Si 3 c Na 4 d Mg 5 e none of the above?

The atom with 14 protons is silicon (Si), so the answer is 2) b Si.

What is a BETA number?

In finance, a beta number measures the volatility or risk of a stock relative to the overall market. A beta greater than 1 indicates that the stock is more volatile than the market, while a beta less than 1 suggests the stock is less volatile. It helps investors assess the potential risk and return of a particular investment.

Why is a neutrino released during positron emission?

To preserve the conservation of; energy, momentum, and angular momentum in beta plus decay. Without the neutrino there is a measurable difference between the energy, momentum, and angular momentum of the initial and final particle. The neutrino rectifies this difference and it's existence was actually postulated before it was ever discovered!

What type of radiation does radium emit?

(Exracted from the wikipedia page] A flame is the product of a highly exothermic reaction (for example, combustion, a self-sustaining oxidation reaction). In other words, it is the visible (light-emitting) part of a fire. Physically, a flame is made up of glowing gases and airborne particles given off by a burning substance; it is not just energy.

Why proportional counter is better than geiger counter?

It depends on the usage.

A proportional counter operates in the linear region, meaning that the amplitude of the pulse is proportional to the energy of the captured ionizing event. Integrating the pulses yields an estimate of the total energy in the field, which is related to dose rate.

A geiger counter, on the other hand, operates in the avalanch region, which means that every ionizing event yields the same amplitude pulse. You lose the ability to estimate dose rate, but you gain sensitivity. The advantage is the ability to quantify, though not qualify, contamination levels.

What particle is emitted when Pu-240 decays to U-236?

240Pu decays to 236U by emitting an alpha particle. You can tell this by looking at the difference in atomic mass. 240 minus 236 is 4, and that is the mass of an alpha particle. You can also tell this by looking at a chart of the nuclides. See the related link below for an example from Brookhaven National Laboratories.

How long is the half life of radioactive water?

The half-life of radioactive water depends on the specific isotope present in the water. Common radioactive isotopes found in water include tritium and carbon-14, which have half-lives of about 12.3 years and 5,730 years, respectively.

Does nuclear energy release greenhouse effects?

Yes.

Most power plants burn fossil fuel (coal, oil and natural gas) to generate electricity and so contribute to global warming.

Burning of these fuels releases long-hidden carbon dioxide (CO2) which adds to the greenhouse gases in the atmosphere. The natural carbon cycle and the natural greenhouse effect are being overwhelmed by this extra gas. The carbon cycle can only distribute about half of it. The greenhouse effect has become an accelerated greenhouse effect, warming the planet.

Power plants like nuclear, hydro, solar, wind, wave, tidal, and geothermal do not release CO2. Biofuel plants release CO2, but as it was only captured during the growing season of the fuel, it is part of the carbon cycle, so it is carbon neutral. None of these renewable energy power plants contribute to global warming.

What is the splitting of an atomic nucleus to form two smaller nuclei of roughly equal mass?

Nuclear fission is the process by which an atomic nucleus splits into two smaller nuclei of roughly equal mass. This process releases a large amount of energy, making it a key component in nuclear power plants and nuclear weapons.

Is radiation measured in emissions sec called the curie?

No, radiation is not measured in emissions per second. The curie (Ci) is a unit used to measure the activity of a radioactive substance, representing the rate of radioactive decay. The unit for measuring radiation exposure is the sievert (Sv).

What is the difference about the nucleus of a radioactive atom?

There is a simple difference between a nucleus and a nucleon. A nucleus is at the center of an atom, and it is that collection of particles, protons and neutrons, that make up the nucleus of that atom. Because atomic nuclei are composed of protons and neutrons, we have come up with the term nucleon to describe any particle that makes up an atomic nucleus. That means either a proton or a neutron, when we talk about them as part of the nucleus of an atom, can be properly called a nucleon. The nucleus of an atom is said to be made up of nucleons. It's just that simple.

Do inertial confinement fusion use lasers?

Yes, inertial confinement fusion uses high-energy lasers to compress and heat a fuel pellet, typically containing deuterium and tritium, to trigger a nuclear fusion reaction. The intense laser beams are focused on the fuel pellet to create the extreme conditions necessary for fusion to occur.

Are the nuclear reactors the same processes occurring in the sun and reactors?

No. The sun produces energy by fusion. It is joining hydrogen atoms into larger helium atoms, which releases energy.

Man-made nuclear reactors produce energy by fission. They break large atoms into smaller atoms, which also releases energy.

What changes in a radioactive material to make it emit radiation?

Radioactive decay occurs when unstable atomic nuclei lose energy to become more stable. This process can involve emitting particles (such as alpha or beta particles) or electromagnetic radiation (such as gamma rays).

When did Franklin discover the structure of atoms?

Benjamin Franklin did not discover the structure of atoms. The atomic theory was formulated by John Dalton in the early 19th century, proposing that all matter is made up of indivisible particles called atoms.

What is the half life of francium?

It is a period of time when the radio active mass is halved.

Radioactive metals disintegrate. In this disintegration the radio active atom emits either/or alpha/beta/gamma particles, and in doing so the given elements changed to a less massive element.

Taking uranium for example.

The isotope 234-U decays with beta emission to the isotopic element 234-Protactinium.in a period of 24 days.

So if you had say 10g of 234-U in 24 days you would have 5g of 234-U . The other 5g would be the element 234-Protactinoum.

How many electrons does ununbium have?

Ununbium is now called Copernicium and it has 112 electrons

Why is information from a newspaper reliable?

Information from a newspaper is generally considered reliable because reporters and editors follow ethical and professional guidelines in gathering and verifying news. Newspapers have a responsibility to provide accurate and unbiased reporting to maintain their credibility. Additionally, most newspapers have fact-checking processes in place to ensure the accuracy of the information they publish.

What is the name given to the electron in the highest occupied energy level?

The electron in the highest occupied energy level is known as the valence electron. These electrons are involved in the formation of chemical bonds and determine the element's chemical properties.

Is the helium nucleus a byproduct of fission?

Yes, but only if the nuclear disintegration is alpha decay. Alpha decay is only one mode of radioactive decay, and in alpha decay, a helium-4 nucleus (the alpha particle) will appear. Beta decay (two types) and spontaneous fission are also modes of radioactive decay, and different particles appear in those events. Links are provided below to Related questions that will help you sort this out.

Is gamma radiation a high energy electrons?

No. It is electromagnetic radiation, beyond the violet end of the visible spectrum.

What is a nuclear resource?

A nuclear resource is a special element that is ran through a nuclear reactor to power or propel and object. It is an object that appears as if it is radioactive or made from a nuclear element ran through reactors or still running .

How are elements with atomic masses greater than uranium made?

Elements with atomic masses greater than uranium are typically produced in supernova explosions, where high-energy processes enable the fusion of heavy nuclei. This process can lead to the creation of transuranic elements such as neptunium, plutonium, and beyond. Additionally, elements beyond uranium can also be artificially synthesized in particle accelerators through nuclear reactions involving target nuclei.
