NEETChemistryp Block Elements (Group 13 & 14)
What effect does the sum of the first three ionization enthalpies have on the chemical properties of these elements?
Options
- AIt has no effect.
- BIt increases their reactivity.
- CIt decreases their reactivity.
- DIt affects their physical properties.
Correct answer
B. It increases their reactivity.
Step-by-step solution
The sum of the first three ionization enthalpies for each of the elements is very high, and the effect of this will be apparent when studying their chemical properties, indicating that it increases their reactivity.
