N. <span>Therefore, the 1p </span>orbital<span> doesn't exist. In the second shell, both 2s and 2p </span>orbitals<span>exist, as it can have a maximum of 8 electrons. In the third shell, only the 3s, 3p and 3d </span>orbitals<span> exist, as it can hold a maximum of 18 electrons. Therefore, the </span>3f orbitals<span> do not exist.</span>
Answer:

that name is :
sodium peroxide
If temperature is held constant, the equation is reduced to Boyle's law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase. However, if you were to maintain a constant volume while decreasing pressure, the temperature would also have to decrease.
