Question

match the correct bohr model to its element.
boron
chlorine
magnesium
potassium

Explanation:

Step1: Determine the atomic number of each element

• Boron (\(B\)) has an atomic number \(Z = 5\) (number of protons \(p^{+}=5\))
• Chlorine (\(Cl\)) has an atomic number \(Z = 17\) (number of protons \(p^{+}=17\))
• Magnesium (\(Mg\)) has an atomic number \(Z = 12\) (number of protons \(p^{+}=12\))
• Potassium (\(K\)) has an atomic number \(Z = 19\) (number of protons \(p^{+}=19\))

Step2: Match the number of protons in Bohr - model to the element

• For model \(B\): The number of protons \(p^{+}=5\), so it matches Boron (\(B\))
• For model \(C\): The number of protons \(p^{+}=17\), so it matches Chlorine (\(Cl\))
• For model \(A\): The number of protons \(p^{+}=12\), so it matches Magnesium (\(Mg\))
• For model \(D\): The number of protons \(p^{+}=19\), so it matches Potassium (\(K\))

Answer:

Boron - B, Chlorine - C, Magnesium - A, Potassium - D
