Given below are two statements: Statement-I : Along the period, the chemical reactivity of the elements gradually increases from group 1 to group 18. Statement-II : The nature of oxides formed by group 1 elements is basic while that of group 17 elements is acidic. In the light of the above statements, choose the most appropriate from the options given below :

1. Both statement I and Statement II are true
2. Both statement I and Statement II are false
3. Statement I is false but Statement II is true
4. Statement I is true but Statement II is false

Correct answer: Statement I is false but Statement II is true

Solution

Statement I is incorrect because chemical reactivity generally decreases from group 1 to group 18, while Statement II is correct as group 1 elements form basic oxides and group 17 elements form acidic oxides.
