Why non-radioactive substances became radioactive when placed near a radium compound?
The particles emitted by a radioactive substance can change other atoms, and in some cases, they will turn into radioactive isotopes.
What are atoms with unstable nuclei and will change into another atom called?
Atoms with unstable nuclei that undergo radioactive decay to transform into another atom are called radioactive isotopes or radioisotopes. These isotopes emit radiation in the form of particles or electromagnetic waves as they decay. This process can result in the formation of different elements or isotopes, depending on the type of decay.
How do radioisotopes of an element differ from other isotopes?
Radioisotopes are unstable isotopes that undergo radioactive decay, emitting particles and/or energy in the process. This distinguishes them from stable isotopes that do not undergo radioactive decay. Radioisotopes are often used in medicine, industry, and research for various applications due to their unique properties related to their decay process.
What happens to the atomic mass number in a radioactive substance?
In a radioactive substance, the atomic mass number may change as a result of radioactive decay. During radioactive decay, radioactive atoms undergo nuclear reactions, which can lead to the emission of radioactive particles such as alpha or beta particles. These emitted particles can cause a change in the number of protons and neutrons in the nucleus, resulting in a different atomic mass number for the resulting atom or isotope.
What is a radioactive atoms?
Radioactive atoms are atoms that have unstable nuclei, which can undergo radioactive decay to become more stable. During this process, they emit radiation in the form of alpha particles, beta particles, or gamma rays. This emission of radiation can cause a change in the atom's composition or energy level.
What is the process in which elements change to other elements by emission of ionizing particles?
Radioactive decay.

What is the process by which elements change to other elements by emission of ionizing particles?
This process is known as radioactive decay. During radioactive decay, unstable atoms release ionizing particles such as alpha particles, beta particles, or gamma rays to transform into more stable elements. This is a natural process that helps the unstable atoms achieve a more balanced state.
What element does promethium change into after emitting beta particles?
Isotopes of promethium decay to isotopes of neodymium.
Does the identity of an atom change during radioactive decay.why or why not?
Well, when an atom undergoes radioactive decay, it can change into a different element. This happens because the nucleus of the atom becomes unstable and releases particles or energy to become more stable. So, while the identity of the atom may change, it's all just a part of nature's way of finding balance and harmony in the universe.
Is radium decaying to lead a chemical or physical change?
The decay of radium to lead is a nuclear change, not a chemical or physical change. It involves the transformation of radium atoms into lead atoms through the process of radioactive decay. This change is due to the emission of alpha particles and does not involve any chemical reactions or changes in the physical state of the substances.
How is the atomic number changed by gamma decay?
There is no change in atomic number with the emission of gamma radiation. Unlike alpha or beta radiation, it does not have any kind of particles. It's emission results only when an excited nuclei goes to an unexcited state by emitting these.
What is a stable isotope?
A stable isotope is an isotope that does not undergo radioactive decay, meaning its nucleus is stable and does not change over time. These isotopes have a constant number of protons and neutrons, making them suitable for use in scientific studies like tracing biological processes or determining the age of rocks. Examples include carbon-12, oxygen-16, and nitrogen-14.
What does emission do to radiation?
Emission refers to the release of radiation from a source. This can occur in various forms such as light, heat, or particles. Emission can either increase the intensity of radiation or change its properties, depending on the source and energy involved.
