N d. N2 10.Which of the following atoms would have the largest first ionization energy? Na b. Ca c. Mg d. Ba e. Sr 11.Which of the following would be classified as most ionic? a. NF b. KF c. CO d. OH e. 12 page 2

Explanation / Answer

6) as the atomic number is 25 ,so ,it is manganese. 7)in this B is the limiting reagent and A is in excess ,so product will be formed according to B so .60 x 2/3 = .40 is the product formed. 9)N - ,b is the answer there will be increased repulsion due to the presence of an extra electron hence size increases. 11) KF has the most ionic nature among all because K is the most electropositive and F is most electronegative among all .
