Question

which of the following is the correct bohr model for sodium, na?

Explanation:

Step1: Recall sodium's atomic number and electron - shell capacity

Sodium (Na) has an atomic number of 11, meaning it has 11 protons and 11 electrons. The first electron - shell can hold 2 electrons, the second can hold 8 electrons, and the third can start filling up after the first two are full.

Step2: Distribute electrons in shells

The first shell gets 2 electrons, the second shell gets 8 electrons, and the remaining 1 electron goes to the third shell.

Answer:

The Bohr model with 2 electrons in the first shell, 8 electrons in the second shell, and 1 electron in the third shell around a nucleus with 11 protons and 12 neutrons.
