Use the information on the following Periodic Table tiles to complete each element's information card. Refer to your quick draw and the Bohr model tutorial. Click on the blue dots to enter your answers. 3 3 7 4 10 10 10 20 10 5 5 5 11 6 15 15 3 15 31 16 What is a valence electron? 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 Match me... Match the the definition to the term. 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 tells you how many protons; electrons in the atom atomic number 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 electrons are found outside of the nucleus. Valence electrons are electrons that are found in the outer most shell.The 1st energy level or shell can hold up to 2electrons. The 2nd and third energy levels can hold up to 8electrons. This means that those energy levels can hold anywhere from one to eight electrons. 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.proton, electron, neutron, shell, nucleus Proton Neutron Nucleus Shell 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 What element is shown below? aluminum silicon sodium magnesium Which element is shown below? boron nitrogen sulfur aluminum Draw the Bohr's model for Neon. REMINDER:The 1st shell only has 2 electrons. The 2nd shell has up to 8 electronsThe 3rd shell has up to 8 electrons. Draw the Bohr's model for Helium. REMINDER:The 1st shell only has 2 electrons. The 2nd shell has up to 8 electronsThe 3rd shell has up to 8 electrons. I have three valence electrons and two shells, who am I? Magnesium Boron Lithium Aluminum The _ tells you how many valence electrons the element has. period number group number The _ tells you how many shells the element has. period number group number
