which of the following is the correct bohr model for sodium, na?
which of the following is the correct bohr model for sodium, na?
Answer
Explanation:
Step1: Recall sodium's atomic structure
Sodium (Na) has atomic number 11. This means it has 11 protons and 11 electrons. The most common isotope has 12 neutrons.
Step2: Determine electron - shell distribution
The first electron shell can hold 2 electrons, the second can hold 8 electrons, and the remaining electrons go to the outer shell. For sodium with 11 electrons, 2 electrons are in the first shell, 8 in the second shell, and 1 in the third shell.
Answer:
The Bohr model with 2 electrons in the innermost shell, 8 in the second shell, and 1 in the outermost shell.
