Question
20-24 Electronegativity is a measure of the energy needed to remove an electron from an atom. the energy released when an electron is added to an atom. the magnitude of the negative charge on a molecule. the attraction by an atom for the shared pair of electrons in a chemical bond. Of the following elements, which one has the highest electronegativity? S F Cs Cl Which of the following elements can form compounds with an expanded octet? N P F Be None of these Below is a list of successive ionization energies (in kJ/mol) for an element in period 3. Identify the else IE_1 = 2250 IE_2 = 3360 IE_3 = 4560 IE_4 = 17,510 IE_5=22,500 IE_6=27,100 S Mg Al Si P Lattice energy of KCI can be represented as:Explanation / Answer
