    sir what about 26

    eduncle-logo-app

    shib according to concept...as you know when stable configuaration comes after removal of electrons than it required more energy to remove electrons...analysing the given data you see that 4th IP is very high...it means after removal of three electrons it gets stable configuration so...valency is 3..

    28) - C. here according to data different between 2nd and 3rd IP is high as compared to 1st IP. it means after removing 2nd electron there must be stable configuration obtained. F have EC - 1s2,2s2,2p5 after removing 2 e it obtained half elctron configuration so it is stable. and removing 3rd electron much amount of energy required so 3rd IP will be high
