What changes take place in the nucleus when an alpha particle is emitted?
In short, alpha radiation occurs when an unstable nucleus emits 2 protons and 2 neutrons from it's nucleus. This means that the atomic number decreases by 2 and the nucleon number decreases by 4.
What is nuclear instability?
Nuclear instability is when the nucleus of an atom is unstable because of an improper ratio of protons to neutrons. Nuclear instability causes radioactive decay because the nucleus emits radiation to stabilize itself.
Where does radioactivity start in an atom?
radioactivity start from the nucleus of an atom which becomes unstable n emit radiation
Technetium-99m emits only gamma radiation why would this type of radiation be used in diagnostic imaging rather than an isotope that also emits beta or alpha radiation?
Because alpha and beta aren't strong enough to penetrate the skin or something
What happens to the mass number of a nucleus when it emits an electron?
When a nucleus emits a beta particle (electron) it is a result of neutron decay. This decay will also release an antineutrino and a proton is left which increases the atomic mass by one thereby changing the element.
Any process where the nucleus emits particles is called?
radiation
What happens to a radioactive nucleus when it emits is gamma particle?
it becomes stable.
What do you mean by radioactive?
An element that has an unstable nucleus and therefore emits alpha, beta and/or gamma radiation.
Is alpha a nuclear form of radiation?
Alpha radiation is a form of radioactivity that is quite common, it occurs when a nucleus emits what is effectively a helium nucleus, that is two protons plus two neutrons
What do you mean by radioactive element?
An element that has an unstable nucleus and therefore emits alpha, beta and/or gamma radiation.
What changes take place in the nucleus when an alpha particle is emitted?
In short, alpha radiation occurs when an unstable nucleus emits 2 protons and 2 neutrons from it's nucleus. This means that the atomic number decreases by 2 and the nucleon number decreases by 4.
Where does the earth emits radiation with greatest intensity at?
The Earth emits infrared radiation at greatest intensity
The sun emits its greatest intensity of radiation in?
The sun emits its greatest intensity of radiation in a spectral region. The spectral region the sun's radiation emits to is the visible region of the spectrum.
What features of radioactive elements make them behave the way they do?
They have a heavy nucleus. Hence it is unstable. Hence it emits radiation in the form of alpha and beta particles to form lighter elements. After emitting these particles, it is in an exited state. It emits gamma radiation to return to its ground state
Why is solar energy transfered to earth by radiation?
That is because every object emits electromagnetic radiation, according to its temperature.That is because every object emits electromagnetic radiation, according to its temperature.That is because every object emits electromagnetic radiation, according to its temperature.That is because every object emits electromagnetic radiation, according to its temperature.
Is the battery emits radiation?
No.
