Dimitri Mendeleev hope this helped!
13 is the number for it on the periodic table and Group 3 is the correct answer hope this helps.
Energy of electron decrease when it move toward neuclus and increase when move away as 2p orbital is away from 2s so energy of electron is less in 2s as compare to 2p
