Answer:
the answer is= NUCLEAR FISSION, NUCLEAR FUSSION, RADIOACTIVE DECAY.
Answer:
Water is a renewable resource because it evaporates out of the oceans to clouds, which generate rain falling on the land. The water then runs into rivers and dams where it is used and the waste is partially cleaned before it makes its route to the sea, where the cycle begins again.
Answer:
its either A or C
Explanation:
i know B is not the answer
Explanation:
Normally, fusion involves two heavy hydrogen nuclides but since we have 4 light hydrogen nuclides, two of which underwent positron emission, thus changing two protons into neutrons plus 2 positrons and 2 neutrinos. The resulting nucleus from this fusion reaction is an He-4 nucleus.
Rubidium is a chemical element with symbol Rb and atomic number 37. Rubidium is a soft, silvery-white metallic element of the alkali metal group, with a standard atomic weight of 85.4678. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidationin air. On Earth, natural rubidium comprises two isotopes: 72% is the stable isotope, 85Rb; 28% is the slightly radioactive 87Rb, with a half-life of 49 billion years—more than three times longer than the estimated age of the universe.
aluminum element is more reactive than rubidium (Rb)
