An electron found in the nucleus An electron found in the first shell There's no such thing as a valence electron 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. Inside the Nucleus Proton & Neutron Outermost Shell or Energy Level Valence Electron In the shells closer to the nucleus (not the outer most shell) Electron Names of places we find electrons Electron cloud, Electron shell, Shells, Energy Levels, Orbitals Refer to the presentation on Canvas in Unit 8 2 to help you. When drawing a Bohr Model, the positively charged protons and neutral neutrons go in the nucleus of the atom. The electrons are found outside of the nucleus. Valence electrons are electrons that are found in the outer most shell.The first energy level or shell can hold up to two electrons. The second energy level can hold up to eight electrons. This means that those energy levels can hold anywhere from one to eight electrons.To help us remember how many electrons can fit in each shell we use Bohr's phone number, which is a silly way to remember how many electrons go in each shell. 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 using the following word bank: Valence Electrons, Electron, Neutrons, Protons, Nucleus, 1st Shell, and 2nd Shell. Valence Electrons Electron Protons Neutrons Nucleus 1st Shell 2nd Shell 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
