How can an alpha particle be described as?
the answer is a positively charged nucleus with two protons and two neutrons
How many alpha particles are produced as one atom of uranium-238 decays to an atom of lead-206?
4 alpha particles were emitted. This is known by the fact that an alpha particle ,on being given out, decrease the mass number of the element by 4.Hence the decrease in mass number in above question is 12 which itself states the answer that 4 alpha particles are emitted. The number of beta particles emitted are 3 beta particle have been emitted.
Which particle determines the nuclear charge?
Protons determine the nuclear charge of an atom. Each proton carries a positive charge and is located in the nucleus of an atom. The number of protons in an atom determines its atomic number and therefore its nuclear charge.
When a parent radioactive nucleus splits by ejecting an alpha particle the remaining nucleus has what left?
two protons and two neutrons less than the original nucleus.* A lower atomic mass (-4)* A lower atomic number (-2)In alpha decay, an alpha particle (helium nucleus) is given off.An alpha particle consists of 2 protons and 2 neutrons. THus the atom loses 2 protons and 2 neutrons. Proton number endows the identity of the element. The daughter nucleus is thus of a different element to the parent nucleus. It also has 2 fewer protons. Radium can decay by alpha emission, losing 2 protons from the original 88, leaving a nucleus of Radon with 86 protons.Neutrons and protons summed give the mass number of the atom. SInce an alpha-decayed nucleus loses a sum of 4 particles (protons and neutrons) the mass number goes down by 4.NovaNET answer: 2 protons and 2 neutrons less
Which lists correctly orders nuclear reactions from most radioactive waste generated to least waste generated within a given period of time?
Fission reactions Fusion reactions Alpha decay Beta decay
This equation is an example of what nuclear decay 232 90 Th to 4 2 He plus 228 88 Ra?
Alpha
How do you find wavelength of an alpha particle when given the velocity?
The wavelength of an alpha particle can be found using the de Broglie wavelength equation: λ = h / p, where λ is the wavelength, h is Planck's constant (6.63 x 10^-34 m^2 kg / s), and p is the momentum of the particle, which is equal to the product of the mass of the alpha particle and its velocity.
Positively charged particle consisting of 2 protons and 2 neutrons which is given off by a radioactive substance is called what?
A radiation particle consisting of two protons and two neutrons is called an Alpha Particle. Alpha Particles have the same structure as a Helium nucleus. There are three forms of radiation, Alpha (Helium nucleus), Beta (a lone electron) and Gamma (an Electromagnetic wave).
Is alpha particle the slowest?
For a given amount of energy, yes. Because its the most massive.
Can hydrogen undergo alpha decay?
No, it cannot. Fission is the "splitting" of an atom, and a hydrogen atom will not fission. Some hydrogen atoms have a neutron stuck to the proton in their nucleus. Some even have two neutrons stuck to that proton. These neutrons can be "knocked loose" in something like a nuclear chair reaction in a weapon. The neutrons then can contribute to the building of the nuclear chain reaction. But fission doesn't happen to hydrogen.
What type of radiation is given off when a nucleus releases two neutrons and two protons?
alpha particle
What is the force of repulsion between an alpha particle and a gold nucleus when the alpha particle passes by the nucleus at a distance of 1pm?
The force of repulsion between the alpha particle and the gold nucleus can be calculated using Coulomb's law, given by F = k * (q1 * q2) / r^2, where k is the Coulomb constant, q1 and q2 are the charges of the particles, and r is the distance between them. Given the charges of an alpha particle and a gold nucleus, and the distance of 1pm, the force of repulsion can be calculated to be extremely large due to the proximity of the particles and the high charges involved.
How can the de Broglie equation be derived?
The de Broglie equation can be derived by combining the principles of wave-particle duality and the equations of classical mechanics. It relates the wavelength of a particle to its momentum, and is given by h/p, where is the wavelength, h is Planck's constant, and p is the momentum of the particle.
What happens to the atomic number when an alpha particle is given off?
Alpha emission in an atom reduces its atomic number by two. A link can be found below to the related question about what alpha decay is.
Charged particles that are given off by the nuclei of radioisotopes as they decay are called?
Charged particles that are given off by the nuclei of radioisotopes as they decay are called decay products or radioactive decay daughters. Examples include alpha particles, beta particles, and positrons. These particles carry energy and momentum away from the decaying nucleus.
What is fouriers equation?
Fourier's equation typically refers to the heat equation, which describes how heat diffuses through a given region over time. It is expressed as ( \frac{\partial u}{\partial t} = \alpha \nabla^2 u ), where ( u ) represents the temperature, ( t ) is time, ( \alpha ) is the thermal diffusivity, and ( \nabla^2 ) is the Laplacian operator. This equation is fundamental in physics and engineering for modeling heat conduction in materials.
