It seems that you've referenced a specific image or link related to the periodic table, but I can't view external content. However, I can still provide information about the atomic model of boron based on its properties.

Boron (B) has an atomic number of 5, meaning it has 5 protons in its nucleus. It typically has 5 electrons in a neutral atom. In its most common isotopes, such as boron-11, it also has about 6 neutrons.

Here’s a brief overview of what the atomic model of boron looks like:

1. **Nucleus**: The nucleus contains 5 protons and around 6 neutrons (in the common isotope).
2. **Electrons**: Boron has 5 electrons that are arranged in energy levels:
- The first energy level can hold 2 electrons.
- The second energy level can hold a maximum of 8 electrons, but in boron, it has 3 electrons.

So the electron configuration for boron is 1s² 2s² 2p¹, showing 2 electrons in the first shell and 3 electrons in the second shell.

If you can describe the options you have for the atomic model of boron, I can help you determine which one is correct!
