please answer these for me they are close together

.what is the maximum number of electrons that can occupy a box in an orbit filling diagram at any level  8,6,14,2

look at the aufbau diagram. what is the maximum number electrons that can occupy any orbit    4,10,14,6

4. sulfur has a atomic number of 16 what  is the electron configuration for an electronically neutral atom of sulfur?  use an aufbau diagram and fill it in if you need t0

5, use the periodic table to determine which ion with a charge of -2 has an electron configiuationof 1s^2 2s^2 2p^6       what is the electrically neutral atom will have an electron configuation of a s^2 2s62 p^4
