The name 'radioactive' may suggest to you that radioactive elements radiate radio waves, but unfortunately that is not so!
The name 'radioactivity' is a misnomer because these elements have nothing to do with radio waves! To understand radioactivity, we need to explore the structure of an atomic nucleus.
So if all the protons repel each other, how does the nucleus stay glued together and remain stable? This force is more stronger than the electromagnetic force, but the range of this force is only limited to size of the nucleus, unlike electromagnetic force whose range is infinite.
Carbon 14 dating denotes
Tex Mex, as we Americans know it today, is a twentieth century phenomenon.
Dictionaries and food history sources confirm the first print evidence of the term "Tex Mex" occured in the 1940s.
The radioactive isotope of carbon was used to develop carbon dating tool, which has made the dating of various relics possible.
Half-Life of a Radioactive Element Half-life is the amount of time required, for half quantity of radioactive element to decay.
For example C, then half of it will have been decayed in 5730 years.
