Part B
It is saying 4s2 4p4
The number 4 (before s or p) indicates last shell number.(principal quantum number)
Shell number is equal to the number of period of element.
4 in the superscript of 4p4 means the element is in 4th group in p block.
Part
Largest principal quantum number indicate the period number.
