Chemistry Question on GROUP 1 ELEMENTS
Alkali metals impart colour to the flame. Their ionisation energies are low.
A
It both Assertion and Reason are true and the Reason is a correct explanation of the Assertion
B
If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion
C
If Assertion is true but the Reason is false
D
If both Assertion and Reason is false
Answer
It both Assertion and Reason are true and the Reason is a correct explanation of the Assertion
