An electron found in the nucleus An electron found in the first shell Any electron in the atom. An electron found in the outer most shell. How many valence electrons does this atom have? 1 2 3 4 Where do you find me? Click on the name of the particle to select it's correct location. Located in the nucleus Proton & Neutron Located in the outermost orbital Valence Electron Located in any orbital of the atom Electron Names of places we find electrons Electron cloud, Electron shell, Shells, Energy Levels, Orbitals Use your notes to fill in the blanks! When drawing a Bohr Model, the positively charged protons and neutral neutrons go in the nucleus of the atom. The nucleus has an overall positive charge. We can tell how many protons an atom has from its atomic number.The negative electrons are found in the electron cloud. The electron cloud is broken down into orbitals. The first orbital can hold two electrons. The second level can hold eight electrons. Valence electrons are found in the outermost energy level. What element is shown in this Bohr Model? Hydrogen Carbon Oxygen Lithium How many TOTAL electrons does this atom have? 2 3 7 14 Parts of the Bohr Model. Label the parts of the Bohr Model. Protons Neutrons Nucleus Electron Valence Electron Which shell do we find valence electrons (VE)? The shell furthest from the nucleus Always the 2nd shell The shell closest to the nucleus Always in the 3rd shell Matching Charges Match the subatomic particle to its correct charge.
