Chemistry is one of the most important sciences because without the knowledge of chemistry many things wouldn’t exist. Bread, soap, rubber, and even the gas stove wouldn’t exist without chemistry. This is because chemistry is the study of matter. And matter is anything that takes up space and has weight.
Some examples of matter are wood, rocks, and animals. Some tools scientists use to study chemistry are microscopes and test tubes.
Matter is made up of atoms. Atoms are very small, and are invisible to the human eye. Protons, electrons, neutrons are part of an atom. These protons, electrons, and neutrons are made of quarks. So far quarks are the smallest things scientists have found that makes up matter.
Elements are substances that are made of only one type of atom. Some examples of elements are sodium, carbon, oxygen, nitrogen, copper, gold, and silicon. These elements were discovered by scientists doing experiments. Want to know when each element was discovered? Here is a timeline. There are probably still other elements to be discovered!
The periodic table of elements is a table with all the elements, the number of protons in an element, the symbol of an element, etc. The purpose of this table is to help with predicting new elements and is a way to quickly see the properties of the known elements. An example of what the periodic table look like is shown on the right.
I think chemistry is one of the hardest things I’ve had to study in Science; it has so much information to learn.
I think the most interesting thing about chemistry so far is how scientists keep digger deeper and deeper to find things like quarks and what makes quarks. It just gets more and more detailed.
