which of the following is the correct bohr model for fluorine, f? a b c
which of the following is the correct bohr model for fluorine, f? a b c
Answer
Answer:
A. Option Text
Explanation:
Step1: Determine atomic number
Fluorine has atomic number 9, so 9 protons.
Step2: Determine number of neutrons
Mass - number is 19, neutrons = 19 - 9 = 10.
Step3: Determine electron - shell configuration
First shell holds 2 electrons, second shell holds 7 for fluorine. Option A shows 2 electrons in first shell and 7 in second shell with 9 protons and 10 neutrons in nucleus.
