which of the following is the correct bohr model for aluminum, al?
which of the following is the correct bohr model for aluminum, al?
Answer
Explanation:
Step1: Recall electron - shell capacity rules
The first shell can hold a maximum of 2 electrons, the second shell can hold a maximum of 8 electrons, and the remaining electrons go to the third shell.
Step2: Determine number of electrons in Al
Aluminum (Al) has an atomic number of 13, so it has 13 electrons.
Step3: Distribute electrons in shells
2 electrons go to the first shell, 8 electrons go to the second shell, and (13-(2 + 8)=3) electrons go to the third shell.
Answer:
The Bohr - model with 2 electrons in the first shell, 8 electrons in the second shell, and 3 electrons in the third shell is the correct one for aluminum.
