He atomic number of fluorine is 9. how many electrons does an ion of fluorine have if it is represented by the symbol shown below? 19f1- a. 8 electrons b. 9 electrons c. 10 electrons d. 20 electrons

The atomic number of fluorine is 9.

Atomic number is the number of protons present in the element. The number of electrons and protons is same in a neutral element.

The given ion of fluorine is . It represents a uninegative anion with a mass number of 19.

It is an anion with a charge of -1, this means that there is an additional electron in the ion. The number of electrons in this ion are 9 + 1 = 10 electrons

The correct answer will be C. 10 electrons
