Deuterium resembles hydrogen in properties but:

1. reacts slower than hydrogen
2. reacts vigorously than hydrogen
3. reacts just as hydrogen
4. emits β+ particles

Correct answer: reacts slower than hydrogen

Solution

Deuterium, being an isotope of hydrogen with an additional neutron, has a greater mass which affects its reaction kinetics, causing it to react more slowly than regular hydrogen in chemical reactions.
