4 Thing I Covered in Science - Atomic Science

In science for the past few weeks, we have been doing the topic of Atomic Science. Atomic Science is the study of atoms, elements and different forms of element groups. Here are four things covered.

• Chemical Change vs Physical change: Chemical Changes are changes that involve this such as, colour change, heat is absorbed or released and cannot be easily reversed. Changes happen every day like when you fry an egg or bake a muffin 
• Atoms: Atoms are particles that make up everything, solids, liquids and gases. Atoms are made up of Protons, Neutrons and Electrons and the amount of these depend on which element is. Example: Hydrogen has, 1 Proton, 1 Electron and 0 Neutrons.
• Elements: The elements are the things that make up many things in the world. They are made of atoms and each element contains a different amount of Protons, Neutrons and electrons. Example: Hydrogen has 1 Proton, 1 Electron and 0 Neutrons. However, Chlorine has 17 Protons, 17 Electrons and 18 Neutrons.
• Atomic and Mass Numbers:  Each element on the periodic table has an atomic and mass number. The atomic number gives you the number of Protons and Electrons. The way to calculate the number of Neutrons is subtract the Atomic number from the mass number. An example is Carbon, it is sixth on the periodic table meaning its atomic number is 6. It's mass number is 12.0. 6 taken away from 12 is 6, so Carbon has 6 Protons, 6 Electrons and 6 Neutrons

Thanks for reading my blog, I had a lot of fun with this topic and I did really well on my test. Please give me feedback in the comments as it helps my learning
