When we talk about Dalton's Atomic Theory, there are a few important experiments that really helped develop this idea. Let’s break them down:
Law of Conservation of Mass: A scientist named Antoine Lavoisier discovered something important. He found out that during a chemical reaction, matter cannot be created or destroyed. In simpler terms, the total weight of the substances before and after the reaction stays the same. This helped us understand that everything is made up of smaller parts.
Law of Definite Proportions: Another scientist, Joseph Proust, made a key discovery too. He showed that a chemical compound always has the same elements in the same amounts by weight. This means that when atoms combine to form a compound, they do so in a fixed way.
Law of Multiple Proportions: John Dalton, the man behind the atomic theory, noticed something interesting. When two elements form different compounds, the amounts (or ratios) of one element that combine with a set amount of the other element are simple whole numbers. For example, you might see ratios like 1:2 or 2:3.
These experiments were very important. They helped us understand matter better and led to Dalton’s ideas that atoms are the tiny building blocks of everything around us.
