which of the following is the correct bohr model for lithium, li?

Answer:

The atomic number of lithium (Li) is 3. In the Bohr - model, the first shell (K - shell) can hold a maximum of 2 electrons and the second shell (L - shell) starts to fill up after the first shell is full. So, for lithium, there are 2 electrons in the first shell and 1 electron in the second shell. Without seeing the specific details of the three models in the picture, the correct Bohr - model for lithium should have 2 electrons in the innermost orbit and 1 electron in the next orbit.

Explanation:

Step1: Determine atomic number

The atomic number of Li is 3.

Step2: Recall electron - shell capacity

First shell holds 2 electrons.

Step3: Distribute electrons

2 in first shell, 1 in second shell.
