In science were doing the periodic table of elements and the protons, neutrons, and electron.
I've learned about some of the periodic table and the 3 elements and how they combined.
The Atoms had 3 part Protons, Neutrons, and Electron. Electron is tiny particles that have a negative electrical charge -. Protons are much larger and heavier than an electron and have the opposite charge. Neutrons are large and have a similar mass to protons.
Elements are more than 100 different types of atoms. Each element has its own name. For example Carbon, Oxygen and Gold are all elements. Each element is given its own special symbol. Some elements retain the symbol based on their old Latin name, even though the name of the element has now changed into a more English one.
Chemical change and Physical change are two types of changes that occur in substances. Chemical changes occur when a new substance is formed. When a chemical change occurs there are certain signs to look for. Physical change is not a permanent change. You can easily get back the material that you started with.
