Balancing Redox Reactions in Acidic and Basic Conditions
We know that redox reactions are ones that involve electron transfer. Something is oxidized, and something else is reduced. But these reactions can be tricky to balance when surrounding water molecules are involved in the reaction. Let's...

What is Radioactivity and Is It Always Harmful: Explained in Really Simple Words
Radioactivity is the property through which a heavier, unstable nucleus assumes a more stable state by emitting radiation. The process through which a nucleus turns into a stable one is called radioactive decay. But is radioactivity or...
