Materials White paper Colored pencils or markers Part I: Modeling Elements Elements are identified by their atomic number. The atomic number also determines the number of electrons. This is Important Information for understanding the formation of chemical bónds. Use the example given to create models for the following elements: 1. Oxygen 2. Colcium 3. Chlorine 4. Aluminum 5. Carbon Take a picture a picture of each model and insert them in order using the Lob Report Form m-Bohr Mode's and Electron Configurations. Label each model with the element's name.

To create models of the elements using the Bohr model, you'll need to represent each element's atomic structure, including protons, neutrons, and electrons. Here's a step-by-step guide for each element:<br /><br />### 1. Oxygen (O)<br />- **Atomic Number:** 8<br />- **Protons:** 8<br />- **Neutrons:** Typically 8 (for the most common isotope)<br />- **Electrons:** 8<br /><br />**Bohr Model:**<br />- First shell: 2 electrons<br />- Second shell: 6 electrons<br /><br />### 2. Calcium (Ca)<br />- **Atomic Number:** 20<br />- **Protons:** 20<br />- **Neutrons:** Typically 20 (for the most common isotope)<br />- **Electrons:** 20<br /><br />**Bohr Model:**<br />- First shell: 2 electrons<br />- Second shell: 8 electrons<br />- Third shell: 8 electrons<br />- Fourth shell: 2 electrons<br /><br />### 3. Chlorine (Cl)<br />- **Atomic Number:** 17<br />- **Protons:** 17<br />- **Neutrons:** Typically 18 (for the most common isotope)<br />- **Electrons:** 17<br /><br />**Bohr Model:**<br />- First shell: 2 electrons<br />- Second shell: 8 electrons<br />- Third shell: 7 electrons<br /><br />### 4. Aluminum (Al)<br />- **Atomic Number:** 13<br />- **Protons:** 13<br />- **Neutrons:** Typically 14 (for the most common isotope)<br />- **Electrons:** 13<br /><br />**Bohr Model:**<br />- First shell: 2 electrons<br />- Second shell: 8 electrons<br />- Third shell: 3 electrons<br /><br />### 5. Carbon (C)<br />- **Atomic Number:** 6<br />- **Protons:** 6<br />- **Neutrons:** Typically 6 (for the most common isotope)<br />- **Electrons:** 6<br /><br />**Bohr Model:**<br />- First shell: 2 electrons<br />- Second shell: 4 electrons<br /><br />### Instructions for Creating Models:<br />1. **Draw Nucleus:** In the center of your paper, draw a circle to represent the nucleus. Inside, write the number of protons and neutrons.<br />2. **Draw Electron Shells:** Draw concentric circles around the nucleus to represent electron shells.<br />3. **Place Electrons:** Place dots or small circles on the shells to represent electrons according to the distribution given above.<br />4. **Label Each Model:** Clearly label each diagram with the element's name and its atomic number.<br /><br />### Tips:<br />- Use different colors for protons, neutrons, and electrons to make the model clear and visually appealing.<br />- Ensure that the number of electrons equals the atomic number for each element.<br /><br />Once you have drawn these models, take pictures of each one and insert them into your lab report form in the order specified.
