What would oxygen 17 be if it went through an alpha and beta decay?

Oxygen-17 would become fluorine-17 after undergoing alpha decay, and then it would decay into oxygen-17 again after undergoing beta decay. Alpha decay involves emitting an alpha particle comprising two protons and two neutrons, while beta decay involves either emitting an electron (beta minus decay) or a positron (beta plus decay) to change the nucleus.

What is the nuclear equation for the decay of Po210 if it undergoes 2 alpha decay then a beta decay followed by another alpha decay.?

The nuclear equation for the decay of Po-210 undergoing 2 alpha decays followed by a beta decay and another alpha decay is:

Po-210 -> Pb-206 + 4 He-4 + 2 e-1 + 2 v

This equation represents the series of decays that result in the transformation of Po-210 into Pb-206, with the emission of two helium nuclei (alpha particles), two electrons, and two neutrinos.

Is transmutation of elements and nuclear transmutation are same?

Transmutation of elements generally refers to changing one element into another by altering the number of protons in the nucleus, while nuclear transmutation specifically refers to inducing such changes through nuclear reactions (such as bombarding a nucleus with particles). In this sense, nuclear transmutation is a type of transmutation of elements.

Is the alpha particle mass smaller than a neutron?

Alpha particles (helium nuclei) are much larger and heavier than beta (electrons) and gamma (high-energy photons). This means they do far more damage to anything they hit.

However, it also means can't travel very far and can be stopped by as little as a sheet of paper.

Radioactive isotopes that emit only alpha radiation are not very dangerous, the only danger is breathing in or ingesting the isotope.

A star produces energy by what?

Creating helium from hydrogen in its core. Combining two atoms to form a larger atom, releasing energy. E=MC^2

Why there is no repulsion between free electrons?

Free electrons most definitely repel each other.

Any attempt to create a buildup of electrons in a specific spot will eventually result in the repulsion amongst these electrons to overcome the attempt to collect them.

When you rub your skin against a wool rug on a dry day, you build up a surplus of free electrons on your skin. The repulsion between these free electrons cause this surplus to scatter to all parts of the skin, thus permitting a discharge of them to occur at any place in your skin.

What do quarks have to do with creating a beta particle?

Beta decay involves changing an up quark into a down quark (Beta+) or a down quark into an up quark (Beta-). This causes a neutron to change into a proton (Beta-) and emit a W- boson which decays into a beta particle (electron and electron antineutrino), or, with extra energy, it causes a proton to change into a neutron (Beta+) which emits a beta particle (positron and electron neutrino).

Quarks are involved because protons and neutrons are comprised of quarks in sets of three, two up quarks and one down quark to form a proton, and two down quarks and one up quark to form a neutron.

Does beta decay occur during the rearrangement of protons and neutrons in the nucleus?

Yes, beta decay is one of the processes that can occur during the rearrangement of protons and neutrons in the nucleus. Beta decay involves the transformation of a neutron into a proton or a proton into a neutron, along with the emission of a beta particle (electron or positron) and a neutrino.

What will alpha particles be when pick up electrons and stabilizes?

Alpha particles are helium nuclei. They don't change, per se, when they "pick up electrons", they just become non-ionic, and their charge becomes zero. They were, and become, so to speak, plain helium.

What correctly describes the charge of beta particles and alpha particles?

Beta particles have a negative charge, while alpha particles have a positive charge. Beta particles are electrons or positrons, while alpha particles are helium nuclei consisting of two protons and two neutrons.

What is the gravitational force on the moon?

1.623 newtons per kilogram of mass.

That's 16.55% of the gravitational force on Earth.

What can replace the growing need for electricity in nations other than nuclear reactors and power plants?

Renewable energy sources such as solar, wind, hydroelectric, and geothermal power can provide sustainable alternatives to nuclear reactors and power plants for meeting the growing need for electricity in nations. These sources are environmentally friendly, abundant, and can be harnessed to produce electricity without harmful emissions. Additionally, advancements in energy storage technologies can help to maintain a reliable supply of electricity from these sources.

What do you call a medical practitioner who treats cancer patients by means of alpha or beta particles?

A medical practitioner who treats cancer patients using alpha or beta particles is called a radiation oncologist. They specialize in using radiation therapy to target and destroy cancer cells while minimizing damage to surrounding healthy tissues.

Why does a coolant have to travel through sealed pipes?

A few of the reasons:

1. So that the coolant does not leak out of the system.

2. So that the coolant can be made to circulate through the pipes (pressure is required).

3. So that Pressure can build up in the cooling system. This allows the coolant to reach a higher temperature before boiling. Once at its boiling point, the temperature will not rise, and additional cooling is inhibited.

What happens if an atom of uranium loses a proton?

If an atom of uranium loses a proton, it becomes an atom of an element with one less proton in its nucleus, known as an isotope of a different element. This change can alter the atomic number, mass number, and chemical properties of the atom.

What does this quote saying life is half spent before you know what it is?

This quote suggests that people often spend the first half of their lives figuring out what life truly means or discovering their purpose. By the time they gain this understanding, half of their life has already passed, highlighting the importance of self-reflection and awareness in order to live a fulfilling life.

Solar system model of the atom?

A many-particle system where the behavior of each particle at every instant depends on the positions of all the other particles cannot be solved directly. This is not a problem restricted to quantum mechanics. A classical system where the same problem arises is a solar system with several planets. In classical mechanics as well as in quantum mechanics, such a system has to be treated by approximate methods

What is relation between GPS and magnetic field?

There is no relationship between GPS (Global Positioning System) and magnetic fields. The GPS system is based on a network of satellites that provide a reference datum that is based on position, regardless of magnetic field.

What is nuclear overhauser effect?

The nuclear Overhauser effect (NOE) is a phenomenon in nuclear magnetic resonance (NMR) spectroscopy where nuclear spins of different atoms influence each other through space, affecting the NMR signals. This effect provides useful distance information between atoms in molecules, helping determine molecular structures. NOE is often utilized in structural studies of proteins and other biological molecules.

What type of field would deflect alpha and beta particles?

An electromagnetic field would deflect alpha and beta particles. Charged particles like alpha and beta particles are affected by electromagnetic forces, causing them to change direction when passing through an electromagnetic field.

What does the term half life mean and give the half life of a few substances?

The term half-life is applied to the time it takes half of a sample of a radioactive substance to decay. It really is as simple as that, but we'd better add a few things to make it clear. Let's look a bit more closely.

Radioactive materials or substance are unstable. That is, the nuclei of the atoms of radioactive materials are unstable, and they will want to undergo a change that will allow them to get to a more stable state. Radioactive decay is the term we apply to the nuclear decay of these materials.

Radioactive materials undergo decay at a given rate. If we have an atom of a radioactive material it will eventually decay, but we cannot be sure when a specific atom will actually decay. But we can do a statistical analysis of a large sample and get an accurate answer. By carefully measuring decay events and making statistical calculations, we have arrived at some very accurate figures for the half-lives of radioactive materials. They vary widely from the tiniest fractions of a second to many billions of years.

Here are some common radioisotopes and their half-lives:

  • Uranium-238 has a half-life of 4.468 x 109 years. That's 4.468 billion years.
  • Plutonium-239 has a half-life of 24,100 years.
  • Cobalt-60 has a half-life of 5.2714 years.
  • Radon-222 has a half-life of 3.8235 days.
  • Carbon-14 has a half-life of 5,730 (+/- 40) years.

The half-life is the time it takes for one-half of something (usually a radioactive isotope) to decay.

What is produced when billions of uranium nuclei are split apart in a fission reaction?

When billions of uranium nuclei are split apart in a fission reaction, they release a large amount of energy, multiple new nuclei, and neutrons. This process is used in nuclear power plants and nuclear weapons.

What is the half life of promethium?

Promethium 145 has a half life of 17.7 years.

Promethium 146 has a half life of 5.53 years.

Promethium 147 has a half life of o.22 years.

What substance is used in a nuclear reactor to absorb heat released from the reactor?

Coolant, such as water or a specific type of liquid metal, is used in a nuclear reactor to absorb the heat released during the nuclear fission process. The coolant carries away the heat and helps to regulate the temperature within the reactor to prevent overheating.
