There are three types of simulations within this virtual lab, Atom, Symbol, Game. You will build atoms and ions with "Symbol" Build an Atom 7 +1 Li He Atom 3 Game Symbol First, click "Symbol". Use the protons, neutrons, and electrons to build a }H atom, a ¿°F atom, a ¿º0²- ion, and a Li* ion. Next, take screen shots of the atoms and ions that you build. Make sure the protons, neutrons, and electrons that you used (upper right of the screen), and the symbol of elements (on the right side of the screen) are included within your pictures. Use the default model "Orbit" (Bohr's model) when you take the screen shot. You can switch the model to "Cloud" (quantum mechanics model) if you wish to see how it looks like. But don't take the screen shots within "Cloud" model. You will learn both Bohr's model and quantum mechanics model of atoms in Chapter 3 of Atom Frist (2nd edition).

NucleonsThe term nucleon refers to the particles found in the nucleus of an atom, namely protons and neutrons. A single hydrogen atom (one proton plus one electron) has a mass of 1.007825 amu. A single neutron has a mass of 1.008665 amu. Note that amu stands for "atomic mass unit" and is sometimes abbreviated with the symbol uu. 1 uu is equivalent to 1.665387×10-27 kgPart A Calculate the mass defect of the fluorine nucleus 19-9F.
