The correct answer is B. An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.
Explanation:
Electrons are negatively charged particles found in atoms. These different from protons and neutrons are not located in the nucleus of the atom but orbit it. Additionally, electrons do not orbit the nucleus following a linear pattern but they have a wave-like behavior which means they move in a three-dimensional space or area known as electron orbital in which they can be found most of the time, this space of area is determined depending on energy, momentum, and other factors. Thus, an electron orbital is "a three-dimensional space where an electron can be found 90% of the time".
Answer: false
because Biodiversity is the biological variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity.
Nuclear power plants use the energy originating from the splitting or uranium atoms to produce steam, which in turn drives a turbine generator.
The main problem with this form of energy production is the byproduct from the nuclear reactors known as radioactive waste. Although it is no longer efficient for the energy production, this waste is still radiating large amounts of heat and radiation. Thus, they are very hazardous as they are fatal on direct exposure and can contaminate the environment.
Due to the extremely long half-life, long term storage for this waste is extremely problematic. However, if the decay rates were much faster, then the half-life would also be much shorter. Thus, short term storage solutions could be found.
Excepting the nuclear waste and the potential accidents (which are minimized in modern plants), nuclear energy does not immediately affect the climate on earth. With short half-lives, nuclear energy would perhaps become more popular than solar or wind energy as it is more reliable and efficient.
