Element | \[I{{E}_{1}}\] | \[I{{E}_{2}}\] | \[I{{E}_{3}}\] |
P | 495.8 | 4562 | 6910 |
Q | 737.7 | 1451 | 7733 |
R | 577.5 | 1817 | 2745 |
A) Q: Alkaline earth metal
B) P: Alkali metals
C) R: s-block element
D) They belong to same period
Correct Answer: C
Solution :
[c] R is p-block element, because difference between \[I{{E}_{2}}\] and \[~I{{E}_{3}}\] is not very high as compared to between\[I{{E}_{1}}\] and \[I{{E}_{2}}\]; hence stable oxidation state of R will be higher than +2.You need to login to perform this action.
