Answer: Dmitri Mendeleev
Explanation: He invented it, since he wanted to arrange all the elements.
Answer:
sp atomic orbital
Explanation:
CO has a triple bond, which is composed of one sigma bond and two pi bonds. Pi bonds are formed using one p orbital from each atom, so the carbon atom must have two unhybridized p orbitals in order to form two pi bonds. The other s and p orbitals that it has are hybridized together to form two sp orbitals. One of the sp orbitals is used in the sigma bond and the other holds the lone pair.
Answer:
A) Fission reactors release harmful gases into the atmosphere — mainly CO₂.
Explanation:
Fission reactors release no CO₂ into the atmosphere.
B, C, and D are correct.
1. According to Rutherford and soddy's law of Beta emission:
3. According to Rutherford and soddy's law of Alpha emission:
4. The process in which two or more light nuclei are combined to form a single nucleus with the release of tremendous amount of energy is called a nuclear fusion. The inner core of Sun is at very high temperature and is suitable for fusion. In fact the source of energy of Sun and other stars is nuclear fusion reactions.
