Would an atom of radioactive gold be more likely to decay by alpha emission or beta emission?
Gold never decays by alpha emission, it either decays by -beta, +beta, K capture, or gamma emission depending on isotope.Natural gold is isotopically pure gold-197, which is stable.
Why is the age of a gold ingot is often mentioned because Gold is not radioactive?
natural isotope of gold is 197 and he is stable element and not with radioactive decay why the gold ingot are often associated with age?
What is the equation for alpha decay of mercury 201?
The equation for alpha decay of mercury-201 is: ^201Hg -> ^197Au + ^4He This means that mercury-201 decays into gold-197 and helium-4 by emitting an alpha particle.
Can radioactive gold rust?
No, radioactive gold cannot rust. Rusting is a chemical reaction that occurs with iron and other metals when exposed to oxygen and moisture, but gold does not undergo rusting. Radioactive decay in gold may lead to changes in its properties and composition, but it does not rust like iron.
Gold-185 undergoes alpha decay. What is the equation for this reaction?
The alpha decay of gold-185 can be represented as (^{185}{79}Au \rightarrow ^{181}{77}Ir + ^4_2He), where (^{185}{79}Au) represents gold-185, (^{181}{77}Ir) represents iridium-181, and (^4_2He) represents an alpha particle.
Which type of particles did Rutherford fire at gold foil?
Rutherford fired alpha particles at the gold foil during his famous gold foil experiment. These alpha particles were positively charged and were emitted from radioactive elements.
Is an radioactive metal gold?
To some extent most elements are radioactive whenever there is a possibility of an unstable isotope. However, generally speaking, gold is not considered to be radioactive. Having said that, radioactive gold can be made.
Can elements be changed into another substance?
Yes, its called transmutation. It is the process by which one element changes into another. This can only be done with a nuclear reaction, but alchemists once believed it might be possible, for example, to transmute lead into gold. They tried many bizarre things, but were never successful. Only nuclear reactions, such as fusion, fission, radioactive decay, etc, can induce a transmutation. Alpha decay is a kind of radioactive decay in which an alpha particle is emitted from an atom. An alpha particle consists of two protons and two neutrons. Therefore, when an atom of an element undergoes alpha decay, it loses two protons, which changes the atom from one element to another. This is because each different element is identified by the number of protons in its atomic nuclei.
Can you convert a piece of rock into gold?
An earth substance can become another earth substance only through the decay of radiation, or through compression. That said, there are no radioactive materials that will decay into gold, and none that can be compressed to form it. The short answer to your question is: No, you cannot convert rock to gold.
What is a radioactive particle that is made up of two neutrons and two protons?
Used by Rutherford in his experiment made of two protons and two neutrons are alpha particles. Rutherford discovered the nucleus using his gold foil experiment.
What is gamma half life?
Most gold is made up of isotopes that have never been observed to undergo radioactive decay and therefore has no known half-life. Some synthetically prepared isotopes of gold may be radioactive and thus have a half-life, the length of which would depend on the particular isotope.
The following equation is an example of decay 185 79 Au -- 4 2 He plus 181 77 Ir?
