Write the nuclear equation for the depicted process. Tritium and deuterium undergo fusion to form an alpha-particle and a neutron. How do unstable isotopes form stable isotopes? a. by emitting radioactive particles from their nuclei b. by radioactive attraction c...
Why is the pacemaker potential of the AV and SA node cardiomyocytes unstable? (i.e., what is the molecular basis of the said instability?) What does the term "circadian" mean? How often does this rhythm repeat itself? What makes this rhythm possible?
Carbon-14 is more unstable than carbon-12, so it's radioactive: it naturally disintegrates, giving off subatomic particles in the process, to turn itself into nitrogen. Carbon-12 and carbon-14 are called isotopes of carbon. An isotope is simply an atom with a different number of neutrons ...
A stable particle with positive charge equal to the negative charge of an electron Common Curiosities Can a positron exist freely in nature? Positrons are generally unstable and annihilate upon contact with electrons. 15 What is a positron? A positron is the antimatter counterpart of an electron ...
The r-process begins when the seed nuclei of iron are bombarded with these free neutrons, soaking them up. Stableatomsof iron, such as the isotope iron-56, have 26 protons and 30 neutrons. The excess of neutrons granted to iron by neutron capture makes the iron atoms unstable and radioact...
But nuclei are not perfectly stable, and over time, they decay, emitting particles and energy. Each element that undergoes radioactive decay, or more specifically the isotope of the element being studied, has its own characteristic half-life, which can be used to predict how many nuclei will ...
What is an unstable radioactive isotope? Is rust a synthesis reaction? What is electrolysis in chemistry? In an isotope, which part of an atom changes? What are redox half reactions? What element has all radioactive isotopes? What is H2SO4 in chemistry?
What makes an atom radioactive? What remains after a sample undergoes two half-lives? Half-life is the time it takes for half of a sample of radioactive atoms to decay. True or False. What causes an isotope to be radioactive?
When are atoms most stable? What is the net charge of an atom? What are the two parts of an atom? What is the history of an atom? What makes an isotope stable or unstable? Which electrons are most responsible for the properties of an atom? What is an atom that has a different numb...
Describe with your own terms what an isotope is. What happens to isotopes that are unstable? What are the mechanisms by which unstable isotopes may decay into stable isotopes? How may these natural processes be used by chemists to make measurements in the medical...
