What is the meaninq of two isotopes stable and unstable isotopes?
Isotopes are atoms of the same element with different numbers of neutrons. Stable isotopes have a balanced number of protons and neutrons, meaning their nuclei do not decay over time. Unstable isotopes, also known as radioactive isotopes, have an imbalance of protons and neutrons, causing their nuclei to decay and emit radiation over time.
What is a stable isotope?
Stable isotopes are chemical isotopes that are not radioactive, meaning that they do not spontaneously undergo radioactive decay.
All isotopes radioactive?
No, there are many stable isotopes.
Is Mercury stable or radioactive?
It is stable, although there are heavier isotopes that could be radioactive.
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.
Is O radioactive?
If you mean oxygen: like most elements, it has both stable isotopes, and unstable (i.e., radioactive) isotopes. 16O, 17O and 18O are stable; the unstable (radioactive) isotopes include 15O and 14O.
Does americium has stable isotopes?
All the isotopes of americium are radioactive and unstable.
What are elements with no stable isotopes called?
Radioactive.
How radioactive is hydrogen?
Hydrogen is not radioactive; its two most common isotopes are stable.
Why does radon undergo radioactive decay?
No stable isotopes.
How many stable nuclides exist for elements that have and atomic number above 83?
All isotopes of all elements with atomic number similar or greater than 84 are radioactive, and don't have stable nuclei.
Does argon have isotopes?
yes, all elements have isotopes. some stable, some radioactive.
