How does the structure of the atom determine its ability to bond with other atoms? In this virtual lab you will build a model of an atom for several elements. You will be given the atomic number and atomic mass of the element. Recall that the number of protons in an atom is equal to the atomic number of the element. The number of neutrons is the atomic mass minus the atomic number. The number of electrons in a neutral atom is equal to the number of protons. You will use the Bohr model of the atom to place the electrons in the correct energy level, or orbital. The first energy level holds a maximum of two electrons; the second holds a maximum of eight electrons. From the model of the atom, you will determine whether or not it is possible for the atoms of the element to bond with other atoms.
