Why is the positron emitter more than beta emitter in medium nuclei?
Electrons being negatively charged will be attracted by the protons within the nucleus and so they come after spending energy against the force of attraction. But positron being positively charged will be repelled by positively charged portons. Hence the energy difference between electron and positron emission in case of beta decay
What is a beta emitter?
In physics, an alpha emitter is a radioactive substance which decays by emitting alpha particles.
Does a beta particle have an identical charge to an electron?
Yes, a beta particle is either an electron or a positron. In beta decay, an electron is emitted (beta-minus decay), which has a negative charge, while a positron is emitted in beta-plus decay, which has a positive charge.
Which radioisotope is a beta emitter?
90-Sr is the answer.
What are the properties of an Beta particle?
A beta particle is an electron (or positron) with high energy and speed.
What is the symbol for a positron?
A positron is the antiparticle of the electron. We write the electron as e- as it is negatively charged. We write e+ or β+ for the positron. The latter symbol uses the Greek letter beta as positron emission is one of the two forms of the radioactive decay known as beta decay. Links can be found below.
When is the decay particle beta?
A beta particle is either an electron, or a positron (aka "anti-electron").
How many nucleons does a beta particle have?
None. A beta particle consists of a single electrons or positron.
What does the e represent in beta decay equations?
In beta decay equations, e- refers to an electron (in beta-), and e+ refers to a positron (in beta+).Not asked, but answered for completeness, ve refers to the electron neutrino that accompanies the positron, and v-e refers to the electron antineutrino that accompanies the electron.
A beta particle is actually what?
Depending on the type of beta decay, it's either an electron or its antiparticle, the positron.
What do most scientists think a beta particle actually is?
A beta particle can be an electron, or a positron (anti-electron).
What are beta particles made up of?
Usually an electron, sometimes a positron.
