I think this question should be read (and written) like:"What is the electron configuration ending in 4s2 4p5 " because 4p2 4p5 is an unusual and even impossible ending of any electronconfiguration.Answer:Bromium, number 35, ends with ... (3d10) 4s2 4p5 (period 4, group 17)
argon is because it's the last noble gas used to get to Br.. it's like a short cut, instead of writing 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^5 you can skip a lot of it by taking th last noble gas used which is the 3p^6(Ar) and continue from there like so: [Ar] 4s^2 3d^10 4p^5
