  8. Draw a diagram showing the charges of each part of the atom.

  9. Draw a Diagram of an Atom

  10. Draw a diagram showing the charges of each part of the atom.

  11. Describe Proton • Protons are positively charged particles found in the atomic nucleus. Protons were discovered by Ernest Rutherford.. • Experiments done in the late 1960's and early 1970's showed that protons are made from other particles called quarks. Protons are made from two 'up' quarks and one 'down' quark.

  12. Describe Neutron • Neutrons are uncharged particles found in the atomic nucleus. Neutrons were discovered by James Chadwick in 1932. • Experiments done in the late 1960's and early 1970's showed that neutrons are made from other particles called quarks. Neutrons are made from one 'up' quark and two 'down' quarks.

  13. Describe Electron Electrons are negatively charged particles that surround the atom's nucleus. Electrons were discovered by J. J. Thomson in 1897. Electrons determine properties of the atom. Chemical reactions involve sharing or exchanging electrons.

  14. Describe Nucleus The nucleus is the central part of an atom. It is composed of protons and neutrons. The nucleus contains most of an atom's mass. It was discovered by Ernest Rutherford in 1911.

  15. Describe Isotope Atoms that have the same number of protons but different numbers of neutrons

  16. Describe Isotope Example: http://education.jlab.org/glossary/isotope.html

  17. What is the Electron Cloud Model? Model of the atom pictures the electrons moving around the nucleus in a region called an electron cloud. The electron cloud is a cloud of varying density surrounding the nucleus. The varying density shows where an electron is more or less likely to be. Atoms with electrons in higher energy levels have additional electron clouds of different shapes that also show where those electrons are likely to be.
