Question

how many electrons are in a fluorine ion, f⁻? enter the answer check it

Explanation:

Step1: Determine fluorine's atomic number

Fluorine has an atomic number of 9, so a neutral fluorine atom has 9 electrons.

Step2: Account for the negative charge

The \( F^- \) ion has a -1 charge, meaning it has gained 1 electron. So we calculate \( 9 + 1 \).
\( 9 + 1 = 10 \)

Answer:

10
