Question

student name: ____________________________ date: _______________ period: model 1: (use the initial from your first name to determine your element.) __________________ bohr model lewis dot model 2: (use the initial from your last name to determine your element.) ____________________ bohr model lewis dot

Explanation:

This is a worksheet for creating Bohr models and Lewis dot structures of elements, likely for a chemistry (Natural Science subfield) class. To complete it:

Step 1: Determine the element for Model 1

Take the initial of your first name. For example, if your first name is "Isabella", the initial is "I". Find the element with symbol "I" (Iodine, atomic number 53).

Step 2: Draw the Bohr Model for Iodine

• Nucleus: Write "53p⁺, 74n⁰" (53 protons, 74 neutrons, since mass number ≈ 127, 127 - 53 = 74).
• Electron shells:
• 1st shell: 2 electrons (max for n=1).
• 2nd shell: 8 electrons (max for n=2).
• 3rd shell: 18 electrons (max for n=3).
• 4th shell: 18 electrons (max for n=4).
• 5th shell: 7 electrons (valence shell, 53 - (2+8+18+18) = 7).

Step 3: Draw the Lewis Dot Structure for Iodine

• The Lewis dot structure shows valence electrons. Iodine has 7 valence electrons. Write the element symbol "I" and place 7 dots (or "x") around it, one on each side (e.g., 2 on top, 2 on right, 2 on bottom, 1 on left, or any arrangement with 7 total).

Step 4: Determine the element for Model 2

Take the initial of your last name. For example, if your last name is "Smith", the initial is "S". Find the element with symbol "S" (Sulfur, atomic number 16).

Step 5: Draw the Bohr Model for Sulfur

• Nucleus: Write "16p⁺, 16n⁰" (16 protons, 16 neutrons, mass number ≈ 32, 32 - 16 = 16).
• Electron shells:
• 1st shell: 2 electrons.
• 2nd shell: 8 electrons.
• 3rd shell: 6 electrons (valence shell, 16 - (2+8) = 6).

Step 6: Draw the Lewis Dot Structure for Sulfur

• Sulfur has 6 valence electrons. Write "S" and place 6 dots around it (e.g., 2 on top, 2 on right, 2 on bottom, 0 on left, or any arrangement with 6 total).

Example (First name: Isabella, Last name: Smith)

• Model 1 (Iodine, I):
• Bohr Model: Nucleus (53p⁺, 74n⁰), shells: 2, 8, 18, 18, 7.
• Lewis Dot: $\boldsymbol{\cdot \underset{\cdot}{I} \cdot}$ (with 7 dots total, e.g., 2 above, 2 below, 2 right, 1 left).

• Model 2 (Sulfur, S):
• Bohr Model: Nucleus (16p⁺, 16n⁰), shells: 2, 8, 6.
• Lewis Dot: $\boldsymbol{\cdot \underset{\cdot}{S} \cdot}$ (with 6 dots total, e.g., 2 above, 2 below, 2 right, 0 left).
