Radioactive decays occur when atoms of certain elements have unstable nuclei that release energy and particles to achieve a more stable state. This process can happen through various types of decay, such as alpha, beta, or gamma decay, depending on the element and its specific isotopes. The decay is random and can happen at any time, but it is characterized by a predictable half-life for each radioactive isotope, indicating the time it takes for half of a sample to decay.

What are the names of the elements that have atoms too large and unstable to occur naturally?
These elements are typically referred to as transuranium elements, located beyond uranium on the periodic table. Examples include elements like fermium, mendelevium, and einsteinium, which are artificially produced in laboratories due to their large atomic sizes and unstable characteristics.
What must occur before a radioactive atoms ceases to undergo further radioactive decay?
Before a radioactive atom ceases to undergo further radioactive decay, it must reach a stable configuration or decay into a non-radioactive isotope through the emission of particles or energy. This process continues until the atom reaches a state of stability where it no longer emits radiation.
Is francium pure?
Yes, francium can occur in a pure form, but it is extremely rare due to its high reactivity. Francium is a highly radioactive element that is typically produced in nuclear reactions and decays quickly into other elements.
Is is possible to convert atoms of one element into atoms of another?
According to Dalton's atomic theory chemical reactions occur when atoms are separated, joined, or rearranged. Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction (it is possible only during nuclear reactions and radioactive disintegration).
Why does the periodic table has over 110 elements when only 90 occur on earth?
The higher atomic number elements are radioactive and have long since decayed away (assuming they were here to start with).
Why does radioactivity occur in some elements?
It occurs due to the instability of the element. It is a spontaneous process. Radioactive atoms are known as isotopes.
Why are most elements radioactive?
Most of the natural occurring (isotopes of) elements are NOT radioactive.Though most of all the known isotopes are radioactive but most of them do NOT naturally occur.
Where does decay and radiation occur?
Decay and radiation occur at the atomic level within unstable nuclei of atoms. Decay is the process where an unstable nucleus emits particles or energy to become more stable, while radiation refers to the particles or energy emitted during this process. Both decay and radiation can occur in natural radioactive elements or in artificially created radioactive isotopes.

When Synthesized elements fall apart they are?
When synthesized elements fall apart, they undergo nuclear decay or radioactive decay, which can result in the release of radiation and the formation of other elements as byproducts. This process can occur due to the unstable nature of these artificially produced elements synthesized in a laboratory.
Which element is radioactive and synthetic?
Plutonium is a synthetic element that is radioactive. It does not occur naturally in nature and must be artificially produced through the nuclear fission of uranium.
What are the 100 types of atoms?
There are 118 known elements, not 100 types of atoms. Elements are made up of atoms with specific numbers of protons in the nucleus. The first 92 elements occur naturally, with the rest being synthetic and created in laboratories.
What must occur before a radioactive atoms ceases to undergo further radioactive decay?
Before a radioactive atom ceases to undergo further radioactive decay, it must reach a stable configuration or decay into a non-radioactive isotope through the emission of particles or energy. This process continues until the atom reaches a state of stability where it no longer emits radiation.
Is francium pure?
Yes, francium can occur in a pure form, but it is extremely rare due to its high reactivity. Francium is a highly radioactive element that is typically produced in nuclear reactions and decays quickly into other elements.
Does all radioactive substances are manmade or artificial?
Radioactive elements both occur in nature (Uranium is the prime example) and are made through the works of man (Plutonium is man-made).
How can radioactive particles create ions?
Radioactive particles can create ions through the process of ionization, where the high energy emitted by the particles can knock electrons out of atoms, leaving the atoms with a positive charge (cation) and the freed electrons with a negative charge (anion). This ionization process can occur when radioactive particles interact with atoms in a material, leading to the formation of ions in the surrounding medium.
