    essential concepts for scientists to understand, because they explain how chemicals and elements act and react. Atoms help show what elements do when put in different circumstances and why they do that. An atom’s structure is based on its number of shells or periods. Those are the orbitals surrounding the atom where the electrons are. Atoms are made of electrons, protons, and neutrons, and the number of those depends on the element. The amount of electrons and protons depends on the element’s atomic

    What are atoms? Well, atoms are the base of any chemical element. Atoms consist of in multiple things, in which these things scientists of the past have discovered, and they are so well known, poems and stories are made about them. In fact, the Periodic Table of Elements is made up of atoms. Atoms are the smallest bit of matter. They are matter and matter is them. Atoms are made of multiple things. Their layout is a dense nucleus surrounded by a large cloud of electrons. The “cloud” of electrons

    The element Neon has a symbol of Ne. Neon’s atomic number is 10, which is the same as its protons. The protons and electrons are always the same. That means the electrons are 10 and put into two different rings. On the first ring there will be 2 electrons and on the second ring there is 8 electrons. That gives them a total of 10 electrons. Along with atomic number, protons, and electrons there is a atomic mass which is 20.1797. Neon was discovered by Sir William Ramsay, a Scottish chemist,
