As the electrons move away from the nucleus, it gains energy and becomes less stable. When electron jumps from lower energy level to higher energy level, it gains energy from surroundings which is known as absorption of energy. When an electron jumps from higher energy level to lower energy level, it releases energy which is known as emission of energy. Note that the electron can absorb or emit only that much amount energy which is equal to energy difference between two levels.
Answer: Yes
Explanation:
Yes, i would invest in this idea, Because the procedure looks very lucrative. Because the initial extraction of the energy from the ground requires no fossil fuel to keep the device running or in operation, rather the heat extracted would be used to heat a heat pump which would boil into steam and in turn used to drive a or power a steam engine.
Answer:- oxygen.
Explanations:- The electronic configuration is given and we are asked to figure out the electrically neutral atom that will have the electron configuration, .
The sum of electrons for this electron configuration is 8. If we look at the periodic table then 8 is the atomic number of oxygen.
So, the electrically neutral atom for the given electron configuration is oxygen.
3 covalent bonds (there are 2 electrons in the first orbital and 5 in the second. You still have room for three more)
Answer:
True
Explanation:
Earth is a single interconnected system but it can be subdivided into smaller systems.
