  2. 2. What is an Atom?Everything! They’re the basis ofeverything in the Universe.Atoms are pieces of matter puttogether to make an object.
  3. 3. What is an Atom?Atoms are made up of 3 different parts.Electrons, protons, and neutrons.Inside of these electrons, proton, andneutrons are nucleons and quarks.The proton and nucleons are always inthe middle of the atom.
  4. 4. Protons, Neutrons & Electrons You can find protons and neutrons in the nucleus. A nucleus is the center part of an atom that holds the protons and neutrons. The electrons are always found whizzing around the center in areas called shells.
  5. 5. Neutrons and Protons Electrons Orbitals
  6. 6. Protons, Neutrons & Electrons Each piece has either a "+", "-", or a "0." That symbol refers to the charge of the particle. The electron always has a "-", or negative, charge. The proton always has a "+", or positive, charge. If the charge of an entire atom is "0", or neutral There are equal numbers of positive and negative pieces. Neutral means there are equal numbers of electrons and protons.
  7. 7. What is an Orbital? Electrons are always moving. As the electrons zip around, they can move in any direction, as long as they stay in their shell. These shells, or orbitals, are specific distances from the nucleus. An electron in the first shell, are always closer to the nucleus than the electrons in the second shell.
  8. 8. Shell Basics The center of the atom is called the nucleus. Electrons are found in areas called shells. A shell is sometimes called an energy level. Shells are areas that surround the center of an atom. Each of those shells has a name. Chemists use an "n" value, or the letters K, L, M, N, O, P, and Q. The "K" shell is the one closest to the nucleus, and "Q" is the farthest away. Those "n" values usually match the row number on the periodic table and are also known as energy levels.
