Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
What else can I help you with?
What happens when an unstable nucleus undergoes radioactive decay?
Particles or electromagnetic radiation are emitted.
What part of an atom causes radioactivity?
It is the nucleus of the atom that undergoes change during radioactive decay.
Which particle is emitted from a hydrogen-3 nucleus when it undergoes radioactive decay?
When a hydrogen-3 nucleus undergoes radioactive decay, it emits a beta particle (specifically an electron) and an anti-neutrino to transform into helium-3.
Beta decay of neodymium-144?
Neodymium-144 undergoes beta decay by emitting an electron (beta particle) and converting a neutron into a proton. This converts the neodymium-144 nucleus into the stable samarium-144 isotope. Beta decay is a type of radioactive decay that helps stabilize the nucleus by changing the neutron-to-proton ratio.
What makes a nucleus radioactive?
If you are referring to a cell's nucleus than the simple answer is that's not radioactive. Radioactivity occurs when elemental atoms become unstable due to the loss or gain of additional neutrons; these unstable atoms are referred to as radioactive isotopes. If a cell's nucleus were radioactive it would not last very long, its structure and function would quickly degrade and collapse.
When an unstable magnesium nucleus undergoes gamma decay the nucleus formed is that of what?
When an unstable magnesium nucleus undergoes gamma decay, it remains as a magnesium nucleus. Gamma decay does not change the atomic number or mass number of the nucleus, only releasing a gamma photon to reduce excess energy.
When an unstable krypton nucleus undergoes beta decay the nucleus formed is that of?
When an unstable krypton nucleus undergoes beta decay, it transforms into a stable rubidium nucleus. In beta decay, a neutron in the krypton nucleus is converted into a proton, resulting in an increase of one atomic number while the mass number remains unchanged. This process changes the element from krypton (atomic number 36) to rubidium (atomic number 37).
What happens when an unstable nucleus undergoes radioactive decay?
Particles or electromagnetic radiation are emitted.
How is a stable nucleus different to an unstable nucleus?
A stable nucleus is one which will not decay, whereas an unstable nucleus will decay at some point, which cannot be predicted as decay is a random process, by alpha or beta decay.
Which are unstable elements that decay or break down into differt elements?
Unstable elements that decay or break down into different elements are called radioactive elements. These elements have an unstable atomic nucleus that undergoes radioactive decay, transforming into a different element and releasing energy in the process. Examples of radioactive elements include uranium, radium, and plutonium.
What part of an atom causes radioactivity?
It is the nucleus of the atom that undergoes change during radioactive decay.
What is the decay type of molybdenum?
Molybdenum mainly undergoes beta decay. This decay process involves the emission of beta particles (electrons or positrons) from the nucleus, resulting in the transformation of a neutron into a proton.
What is an unstable nucleus that starts a decay process called?
A nucleus that starts to decay is called a radioactive nucleus or atom. It decays with a known and unique half life by several processes including but not limited to beta decay, alpha decay, electron capture decay, and positron emission.
When an oxygen19 nucleus undergoes beta decay the nucleus formed is that of?
When an oxygen-19 nucleus undergoes beta decay, a nitrogen-19 nucleus is formed. In beta decay, a neutron is converted into a proton, causing the atomic number to increase by one while keeping the mass number the same.
What happens to a nucleus of an unstable atom?
An unstable nucleus can undergo radioactive decay to become more stable. This can involve emitting radiation in the form of alpha particles, beta particles, or gamma rays. The decay process results in a transformation of the nucleus into a different element or isotope.
What are the causes of decay?
An unstable nucleus, which can be caused by:excess of neutronsshortage of neutronsmetastable excited state of nucleus
What does the unstable nucleus of an atom give off during radioactive decay?
An unstable nucleus (radioactive isotope) may emit: alpha particles, beta particles, gamma radiations, electrons, positrons, X-rays, and neutrons, depending on which nucleus is doing the emitting.
