FAQ

Question- What is the most important question in chemistry?

Answer - The most important question of this topic is "Where are the electrons?". There is also information about this - the electron revolves around the nucleus in the atom and its mass is a thousand times less than the smallest atom (hydrogen). Its charge is considered negative.
