TS EAMCET 9-Sep-2020 Shift 2 Solved Paper

Ability of an atom to attract the shared pair of electrons towards itself, is called electronegativity. Fluorine (F) has highest electronegativity among the given species.
Due to small size and seven electrons in its outermost shell, it shows highest electronegativity. At pulling scale, it is considered as 4.0. Hence, option (b) is the correct.
