Answer is: A. f > d > p > s.

Aufbau principle is a scheme used to reproduce the electron configurations of the ground states of atoms by successively filling subshells (orbitals) with electrons in a specific order.

Filling subshells in the following order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f.

The azimuthal quantum number (l) determines its orbital angular momentum and describes the shape of the orbital.  

s-orbitals (for example 1s, 2s) are spherically symmetric around the nucleus of the atom.  

p-orbitals are dumb-bell shaped. l = 0,1...n-1, when l = 1, that is p subshell.  

d-orbitals are butterfly shaped.  

f-orbitals are similar to the d orbital, but cut in half (eight lobes instead of four).

Bas_tet [7]

Hey there!

500 mg of protein is present in 100 mL of solvent as per the concentration 0.5 mg/mL or 500 g/mL ,

So, 250 mg (0.25 g) of serving food need to be added to 100 mL solvent in order to prepare 50 mg of protein/100 mL solution.

Dilution factor = initial amount of protein / final amount of protein

= 6 g / 0.05 g = 120

Hope this helps!
