Just wondering, why are some atoms radioactive and others not?
Not quite. Only certain atoms release neutrons when they undergo spontaneous fission, or when they undergo neutron-induced fission, or in rare cases interaction with a gamma ray or alpha particle.beanybag said:radioactive atoms are isotopes with a certain number of excess neutrons that they "radiate" those neutrons, and give them off slowly. any atom can become a radioactive isotope by just gaining nuetrons.
An atom is considered radioactive if its nucleus is unstable and can spontaneously decay, releasing energy in the form of radiation. This instability is due to an imbalance in the number of protons and neutrons in the nucleus.
The number of protons in an atom's nucleus determines its atomic number and element. The number of neutrons can vary, resulting in different isotopes of the same element. This variation in the number of protons and neutrons can cause an atom to become unstable and radioactive.
Yes, atoms can become non-radioactive through the process of radioactive decay. This is when an unstable atom releases particles and energy until it reaches a stable state. This process can take seconds, minutes, or even thousands of years depending on the atom.
No, not all radioactive atoms are dangerous. Some naturally occurring radioactive atoms, such as potassium-40, are present in small amounts in our bodies and are not harmful. However, high levels of exposure to certain radioactive elements can be dangerous and increase the risk of cancer.
To protect ourselves from the harmful effects of radioactive atoms, it is important to limit our exposure to them. This can include avoiding areas with high levels of radiation, using protective equipment, and following safety procedures in industries that handle radioactive materials. Regular monitoring and proper disposal of radioactive waste can also help reduce exposure.
