1.	Consider the following statements : I. The radius of an atom anion is larger than that of the parent atom . II. The ionization energy generally increases with increasing atomic number in a period. III. The electronegativity of an element is the tendency of an isolated atom to attract an electron. Which of the above statement is/are correct?
Answer» I alone II alone I and II II and III SOLUTION :SIZE of an anion is larger than the corresponding ATOM and the ionization ENERGY generally increases as the size decreases with increasing atomic number in a PERIOD.
