Answer: The nucleus of radium-226 is unstable and hence undergoes decay.
Explanation: Radium has many isotopes. One of them is 
which has 88 protons and 138 neutrons. It is a radioactive isotope and undergoes decay process.
This isotope undergoes alpha - decay and produces Radon-222 isotope.
Equation for alpha - decay follows:
Hence, the nucleus of radium-226 undergoes decay process.
Explanation:
None of them is balanced the total number of individual elements on the reactant side is not equal to that of the product side
Where do the hydrogen and oxygen atoms come from that become part of the glucose molecule made during photosynthesis? The oxygen molecules come from carbon dioxide and water. The hydrogen atoms come from water.
Hope this helps.
The correct answer is A. C3H4 is the three-carbon alkene contains two double bonds. Alkenes are a class of organic compounds with carbon-carbon double bond. The structure for C3H4 is:
