drag and drop the correct answer choice to each answer blank. or, touch the answer choice followed by the answer blank.
students in mr. williamss class are learning about bohr models and the periodic table. in order to draw a bohr model, they must identify the protons, neutrons, and electrons of their chosen element. the bohr model in the picture represents an atom of chlorine (cl). fill in the missing parts of the table to provide more information about the element represented by the atom.
move the answers to the correct boxes.

Explanation:

To solve this, we analyze the Bohr model of Chlorine (Cl):

Step 1: Determine Atomic Number

Atomic number = number of protons. From the model, protons (\(P\)) = 17. So atomic number is 17.

Step 2: Determine Mass Number

Mass number = protons + neutrons. Protons = 17, neutrons (\(N\)) = 18. Thus, mass number = \(17 + 18 = 35\).

Step 3: Determine Number of Electrons

In a neutral atom, electrons = protons. So electrons = 17. Let’s count electrons in the Bohr model:

• Innermost shell: 2 electrons.
• Second shell: 8 electrons (2 + 6? Wait, no—wait, Chlorine’s electron configuration is \(2, 8, 7\)? Wait, the model here: let's count the dots (electrons) on each shell. Wait, the image shows:
• First (innermost) shell: 2 electrons.
• Second shell: 8? Wait, no, the middle shells: wait, the model has three shells? Wait, no, the circles: let's count the green dots (electrons):
• Innermost circle (first shell): 2.
• Second circle: 8? Wait, no, looking at the image: the first (smallest) circle has 2, next has 8? Wait, no, the user’s image: let's recheck. Wait, the Bohr model for Cl (atomic number 17) has electron configuration \(2, 8, 7\) (total 17 electrons: \(2 + 8 + 7 = 17\)). But in the image, let's count the green dots:
• Innermost shell (closest to nucleus): 2.
• Second shell: 8? Wait, no, the middle shells: wait, the image shows:
• Innermost circle: 2 electrons.
• Second circle: 8? Wait, no, maybe the shells are: first (2), second (8), third (7). But in the image, let's count all green dots: 2 (innermost) + 8 (second) + 7 (third) = 17. Yes, that matches protons (17), so electrons = 17.

Filling the Table (Common Blanks for Chlorine):

• Atomic Number: 17 (protons = 17).
• Mass Number: 35 (17 + 18).
• Number of Electrons: 17 (neutral atom, electrons = protons).

If the table has blanks like “Atomic Number”, “Mass Number”, “Number of Electrons”, the answers are:

• Atomic Number: 17
• Mass Number: 35
• Number of Electrons: 17

(Note: Since the exact table blanks aren’t shown, but based on the model, these are the key values for Cl’s Bohr model analysis.)

Answer:

• Atomic Number: 17
• Mass Number: 35
• Number of Electrons: 17

(Adjust based on the specific table blanks, but these are the core values from the model.)
