Which particle determines the nuclear charge?
The nuclear charge is the term given to the electric charge on the nucleus, and it is simply found by counting the number of protons.
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.
How can an alpha particle be described as?
the answer is a positively charged nucleus with two protons and two neutrons
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
What are three kinds of radioactivity?
The three major types of radioactivity are: # Alpha Radiation Alpha radiation consists of a stream of positively charged particles, called alpha particles, which have an atomic mass of 4 and a charge of +2 (a helium nucleus). When an alpha particle is ejected from a nucleus, the mass number of the nucleus decreases by four units and the atomic number decreases by two units. For example: 23892U -> 42He + 23490Th The helium nucleus is the alpha particle. # Beta Radiation Beta radiation is a stream of electrons, called beta particles. When a beta particle is ejected, a neutron in the nucleus is converted to a proton, so the mass number of the nucleus is unchanged, but the atomic number increases by one unit. For example: 23490 -> 0-1e + 23491Pa The electron is the beta particle. # Gamma Radiation Gamma rays are high-energy photons with a very short wavelength (0.0005 to 0.1 nm). The emission of gamma radiation results from an energy change within the atomic nucleus. Gamma emission changes neither the atomic number nor the atomic mass. Alpha and beta emission are often accompanied by gamma emission, as an excited nucleus drops to a lower and more stable energy state. Alpha, beta, and gamma radiation also accompany induced radioactivity. Radioactive isotopes are prepared in the lab using bombardment reactions to convert a stable nucleus into one which is radioactive. Positron (particle with the same mass as an electron, but a charge of +1 instead of -1) emission isn't observed in natural radioactivity, but it is a common mode of decay in induced radioactivity. Bombardment reactions can be used to produce very heavy elements, including many which don't occur in nature.Submitted by kuasimodo
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.
Charged particles that are given off by the nuclei of radioisotopes as they decay are called?
Either an Alpha particle or Beta particle depending on what isotope it comes from
What type of radiation is given off when a nucleus releases two neutrons and two protons?
alpha particle
Which particle determines the nuclear charge?
The nuclear charge is the term given to the electric charge on the nucleus, and it is simply found by counting the number of protons.
How do you find wavelength of an alpha particle when given the velocity?
use de Broglie's wavelength: lambda = h/mv
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.
Which is not one of the waves of the electromagnetic spectrum - UV rays or Alpha rays or Visible light or Infrared rays?
Alpha rays are not part of the electromagnetic spectrum. Alpha particles are the same as helium nuclei, and are given off in nuclear decay.
What is difference between beta particle and an electron?
An electron is the basic carrier of the negative electrostatic charge. It has an anti-matter equivalent (an anti-particle) called the positron. Either an electron or positron can be a beta particle. The reason is that beta decay releases a beta particle, and the type of particle will depend on the type of decay. In beta minus decay, the change in an atomic nucleus will release an electron, and in beta plus decay, the nuclear change will release a positron. Use the link below to learn more about beta decay.
