Answer

Explanation:

Step1: Determine atomic number of Mg

Magnesium (Mg) has an atomic number of 12.

Step2: Distribute electrons in shells

The first shell can hold 2 electrons, the second shell can hold 8 electrons, and the remaining 2 electrons go in the third shell. So for Mg, the electron - shell configuration is 2, 8, 2 in the Bohr model.

Step3: Determine atomic number of F

Fluorine (F) has an atomic number of 9.

Step4: Distribute electrons in shells

The first shell holds 2 electrons and the second shell holds 7 electrons. So for F, the electron - shell configuration is 2, 7 in the Bohr model.

Step5: Determine atomic number of Cr

Chromium (Cr) has an atomic number of 24.

Step6: Distribute electrons in shells

The electron - shell configuration for Cr is 2, 8, 13, 1 (due to its special electron - configuration behavior related to half - filled sub - shells for stability).

Answer:

  1. For Mg in the Bohr model: First shell has 2 electrons, second shell has 8 electrons, third shell has 2 electrons.
  2. For F in the Bohr model: First shell has 2 electrons, second shell has 7 electrons.
  3. For Cr in the Bohr model: First shell has 2 electrons, second shell has 8 electrons, third shell has 13 electrons, fourth shell has 1 electron.
