Question
Mg is the smallest and Sr is the largest P is the smallest and Sr is the largest Mg is the smallest and Sr is the largest P is the smallest and Sr is the largest Which of the following statements is correct about the comparative first ionization energies of the atoms in the following set: Mg, P. Sr. Sb Mg has the largest 1_1 & Sr has the smallest l_1 Mg has the largest 1_1 & Sr has the smallest l_1 P has the largest ; & Sr has the smallest l_1 P has the largest l_1 & Sb has the smallest l_1 Which of the following statements is correct about the comparative electron negative of the following atoms N_0 Si K GeExplanation / Answer
To answer this better, look for the first ionization energy of this atoms. I found these:
Mg = 737.7 kJ/mol
P = 1011.8 kJ/mol
Sr = 549.5 kJ/mol
Sb = 834 kJ/mol
Basing on this we can see that P has the highest ionization energy, followed by Mg, Sb and finally Sr. The correct order is:
P > Mg > Sb > Sr
The third option is the correct one.
Hope this helps
