which of the following is the correct bohr model for boron, b?
Answer
Explanation:
Step1: Determine atomic number of boron
Boron (B) has an atomic number of 5. This means it has 5 protons ($p^+$) and 5 electrons in a neutral atom.
Step2: Analyze electron - shell distribution
The first electron shell can hold a maximum of 2 electrons, and the second shell can start filling up after the first is full. For boron with 5 electrons, 2 electrons will be in the first shell and 3 electrons will be in the second shell.
Step3: Check the Bohr - model options
We need to find the model with 5 protons in the nucleus, some neutrons (boron - 11 has 6 neutrons which is common), 2 electrons in the innermost shell and 3 electrons in the second shell.
Answer:
The Bohr model with 5 protons in the nucleus, 6 neutrons, 2 electrons in the first shell and 3 electrons in the second shell is the correct one for boron.
