To build a model of an ionized atom, you would start with a neutral atom and then remove one or more electrons, resulting in a positively charged ion. If an atom becomes too ionized, it may lose its stability and react more readily with other atoms or molecules. For a radioactive model, you would depict an unstable nucleus with an imbalance of protons and neutrons; this could be represented by showing excess energy or particles being emitted. If the imbalance becomes too great, the atom may undergo radioactive decay, leading to the emission of radiation and transformation into another element or isotope.

What makes americium radioactive?
Americium is radioactive due to its unstable atomic structure, specifically the imbalance between protons and neutrons in its nucleus. This instability causes the americium atoms to undergo radioactive decay in order to achieve a more stable configuration, emitting harmful radiation in the process.
Radioactive substances consist of nuclei that can't be held together by the what?
Radioactive substances consist of nuclei that can't be held together by the strong nuclear force. This force is responsible for keeping protons and neutrons bound within the nucleus of an atom. When this force is not strong enough to overcome the repulsion between protons, the nucleus becomes unstable and undergoes radioactive decay.
What does radioactive decay produces .?
The energy is stored in the atoms - in the forces between protons and neutrons - from the start, as a type of potential energy.
What causes Uranium to be radioactive?
Uranium is radioactive because it is an unstable element with a nucleus that can undergo radioactive decay. During this decay process, uranium releases energy in the form of alpha, beta, or gamma radiation as it transforms into other elements over time. This radioactive decay is what makes uranium useful for nuclear energy and weapons.
When are all atoms radioactive?
An atom "becomes" radioactive when it is created. It's that simple. Radioactivity is a phenomenon associated with atoms that have unstable nuclei. The key is that the protons and neutrons that form the nucleus "don't like" the "arrangement" there and the atomic nucleus is unstable. The "ratio" of protons to neutrons in a nucleus is intrinsically unstable. The instability is something that the nucleus, when it is formed (and by whatever means), has as an innate quality. It is unstable, and it isradioactive, and at some point in time, it will undergo decay, or even spontaneous fission, in the case of certain atoms, like uranium and plutonium.
What happens if the imbalance between protons and neutrons becomes too great?
The atom is unstable.
What is the difference between stable and unstable nuclei?
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance, leading to radioactive decay.
What are the key differences between stable and unstable nuclei?
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance. Unstable nuclei undergo radioactive decay to become more stable.
What makes americium radioactive?
Americium is radioactive due to its unstable atomic structure, specifically the imbalance between protons and neutrons in its nucleus. This instability causes the americium atoms to undergo radioactive decay in order to achieve a more stable configuration, emitting harmful radiation in the process.
What makes an element unstable or radioactive?
The stability of an atom depends on a balance between the numbers of protons and neutrons in its nucleus and also on the total size of its nucleus; atoms with sufficiently large nuclei are inherently unstable. Please see the link.
What is the difference between a non-radioactive substance and a radioactive substance?
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.
What characteristic indicates a atom is unstable?
Forming very strong bonds
What is the difference between a stable and unstable nucleus?
In most atoms the protons and neutrons found in the nucleus are held together strongly. The nuclei of these atoms are said to be stable. However, the neutrons and protons in some atoms are not held together as strongly. These nuclei are unstable and will eventually disintegrate, forming other elements. Isotopes that are unstable are said to be radioactive and are called radioactive isotopes or radioisotopes.
How does nitrogen radioactive differ from a stable atom?
Chemically there is no difference between radioactive nitrogen and stable nitrogen. Both will react the exact same way in all chemical reactions. The only difference between the two is the number of neutrons in the nucleus. This means the only difference is mass. If the nitrogen atom has too many neutrons, it will most likely give off a beta particle. The beta particle shoots out from one of its neutrons. That neutron then becomes a proton and the nitrogen becomes oxygen. If the nitrogen atom has too few neutrons, a proton in its nucleus may capture one of its own electrons and turn into a neutron. This would then turn the nitrogen atom into a carbon atom.
Radioactive substances consist of nuclei that can't be held together by the what?
Radioactive substances consist of nuclei that can't be held together by the strong nuclear force. This force is responsible for keeping protons and neutrons bound within the nucleus of an atom. When this force is not strong enough to overcome the repulsion between protons, the nucleus becomes unstable and undergoes radioactive decay.
How many protons are needed for a element to be naturally radioactive?
Whether an ISOTOPE (not element) is naturally radioactive depends not only on the number of protons, but also on the number of neutrons. For EVERY element, there are radioactive isotopes.There has to be a certain relationship between the number of protons and the number of neutrons, but the relationship isn't a simple one.
What does radioactive decay produces .?
The energy is stored in the atoms - in the forces between protons and neutrons - from the start, as a type of potential energy.
