Neptium-236 has 143 neutrons and a half-life of 154,000 years. It can decay ny electron capture, beta emission and alpha emission. For beta emission, the decay product is Plotunium-236. Hope this answers the question. Have a nice day.
Hey there!:
Copper plating on Zinc will occur via this simple reaction:
Cu²⁺ + 2 e⁻ ⇌ Cu
When a species gains electron, it is reduced. Its oxidation state is decreased. For example, in the above reaction Cu2+ gained 2 electron to get reduced to Cu. Its oxidation state changed from +2 to 0. Hence it is a reduction reaction.
So, the correct answer is :
The copper II ions gain two electrons and are reduced.
Answer B
Hope this helps!
