Predict the chemical behavior of this element. Match the items in the left column to the appropriate blanks in the sentences on the right. The element is in the family and vould have the corresponding properties. The element would be relatively have the first ionization energy than 1037 kJ/mol (the first ionization energy of ). and have a electron affinity, It would be to form compounds with other elements (except fluorine).
