An atom is a natural structure that has protons and neutrons bound (fused) together in a nucleus, and electrons orbiting in energy levels about it. Different combinations of protons and neutrons create different elements or different isotopes of a given element. In any case, when we look across different combinations of protons and neutrons in atomic nuclei, there are instances where atomic instability results when a given combination has been made. There are, quite simply, some combinations of protons and neutrons that are "unacceptable" to the protons and neutrons that make up that combination. This is an unstable atomic nucleus, and it is radioactive. It will eventually decay by some means, and all because that nucleus is unstable and is seeking to "get rid" of the instability by undergoing radioactive decay. The nucleus is attempting to change into a stable form, and if the decay product is another unstable form, then another radioactive decay will eventually occur. And so on until the "end product" is a stable isotope of some element.

What is an unstable atom?
An unstable atom is an atom that has an imbalance in the ratio of protons to neutrons in its nucleus, making it prone to undergo radioactive decay. This decay results in the emission of particles or energy in order to achieve a more stable configuration. Unstable atoms will continue to decay until they reach a state of stability.
What radioactive atoms spontaneously do?
Radioactive atoms spontaneously decay, emitting particles or energy in the process. This decay can result in the transformation of the atom into a different element or isotope to achieve a more stable state.
When an atom undergoes radioactive decay the energy released in the reaction comes from what?
The energy released in radioactive decay comes from the conversion of mass from the parent atom into energy according to Einstein's famous equation, E=mc². This energy is released in the form of radiation or kinetic energy of the decay products.
How can the element Americium change into the element neptunium?
Americium can change into neptunium through a process called alpha decay. During alpha decay, an alpha particle (helium nucleus) is emitted from the nucleus of the americium atom, resulting in the transformation of the americium atom into a neptunium atom.
What is the kind of decay that's results in the formation of a different element?
Alpha decay is a kind of radioactive decay in which an alpha particle is emitted from an atom. An alpha particle consists of two protons and two neutrons. Therefore, when an atom of an element undergoes alpha decay, it loses two protons, which changes the atom from one element to another. This is because each different element is identified by the number of protons in its atomic nuclei.
When an atom undergoes radioactive decay does it become a different element?
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
Is the atom left after decay often radioactive?
Yes, the atom left after decay is often radioactive because the decay process can lead to the creation of unstable isotopes that emit radiation. This radiation can continue to decay until a stable atom is formed.
What is an unstable atom?
An unstable atom is an atom that has an imbalance in the ratio of protons to neutrons in its nucleus, making it prone to undergo radioactive decay. This decay results in the emission of particles or energy in order to achieve a more stable configuration. Unstable atoms will continue to decay until they reach a state of stability.
Which notation is used to represent gamma decay?
The symbol of gamma rays is γ.Between the initial atom and the daughter atom from decay an arrow (→) is placed.
What is when the nucleus of an atom decomposes called?
radioactive decay
What type of atom is used in radiometric decay?
Isotope
What is the term for the element that a radioactive isotope decay into?
The term for the element that a radioactive isotope decays into is called the "daughter product". During radioactive decay, the original isotope transforms into a different element or isotope through a series of decay reactions.
When radioactive decay occurs a atom is always produced by the action?
During any type of radioactive decay, one isotope (type of atom) will convert into a different isotope.
What happens to the atomic number of an atom undergoing alpha decay?
The atomic number of an atom undergoing alpha decay decreases by 2. Not asked, but answered for completeness, the atomic mass number decreases by 4.
What is the effect of pressure on the rate of radioactive decay?
Pressure does not have a significant effect on the rate of radioactive decay, as it is mainly influenced by the instability of the nucleus of the atom. The decay process is determined by the nuclear forces within the atom, which are not significantly affected by external pressure changes.
What is The spontaneous decay of an atom is called?
Nuclear decay.Different types of nuclear decay include:Alpha Decay, where the nucleus ejects a charged particle made of protons and neutrons.Beta Decay, where a neutron turns into a proton, a Beta particle (an electron or positron) and a neutrino.Gamma radiation can also be emitted in these processes.
What radioactive atoms spontaneously do?
Radioactive atoms spontaneously decay, emitting particles or energy in the process. This decay can result in the transformation of the atom into a different element or isotope to achieve a more stable state.
