The 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

Fluorine is a nonmetallic, diatomic gas with the symbol F and atomic number 9. Atomic number represents the number of protons in the atom. When F is neutral it means that the number of protons is equal to number of electrons. But, when F is an ion (F-), the it has more electrons (10) than protons, meaning its an anion.

Explanation:

It is known that atomic number is the number of protons present in an atom. Also, when an atom is neutral then number of protons equal number of electrons.

Hence, fluorine has atomic number 9 so there will be 9 electrons in a fluorine atom. It's electronic configuration will be .

So, in order to acquire stability fluorine atom will accept one electron from another atom. Therefore, it will result in the formation of ion.

Thus, we can conclude that there are total 10 electrons in a fluorine ion.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
