Afbau principle states that the electrons are filled in the orbital according to their energy level. Lower energy shells are first filled and then higher energy shell are filled.
The order of filling of orbitals are s-p-d-f.
So, elements with last electron in respective orbitals show similar properties. And this serves as the basis of format of periodic table.

Answer:
1200 mL
Explanation:
Given data
- Initial pressure (P₁): 600.0 mmHg
- Initial volume (V₁): 400.0 mL
- Final pressure (P₂): 200.0 mmHg
For a gaseous sample, there is an inverse relationship between the pressure and the volume. If we consider the gas as an ideal gas, we can find the final volume using Boyle's law.
Answer:

Answer: The mole fraction of neon in the final mixture is 0.6
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : =total pressure of gases = 5.0 atm
= partial pressure of argon = 2.0 atm
= partial pressure of Neon = ? atm
According to Raoults law, the partial pressure of a gas is equal to its mole fraction mulitiplied by the total pressure.
= mole fraction of Neon
Thus mole fraction of neon in the final mixture is 0.6
