I - Multiple Choice. Please circle the letter of the BEST answer. 2 H 2 all have the same polarity 5. Electronegativity is the energy change accompanying the addition of an electron to a gaseous atom. Electronegativity is the energy required to remove an electron from a gaseous atom.
Electronegativity is the ability of an atom in a molecule to attract electrons toward itself.
Electronegativities increase as you proceed down a group in the Periodic Table. Sketch this orbital. Use average bond enthalpies to estimate D H for the following reaction. For the molecule below, determine the hybridization of the labeled atoms. Write the formulas for the salts, match the appropriate salt with each lattice enthalpy, and explain your choices.
