Fluorine (f) has seven electrons in its outermost shell. fluorine 1. is a metal 2. is a nonmetal 3. fills its shell by giving up seven electrons 4. fills its shell by gaining one electron 5. becomes a positively charged ion 6. becomes a negatively charged ion you can select as many as you want

is a nonmetal

fills its shell by gaining one electron

becomes a negatively charged ion

Explanation:

Fluorine is in group 7 of the periodic table and in period 2. Elements found in group 7 are mostly non metals. This non metals mostly gain electron during bonding with other atom of elements.

Fluorine fills it outer shell by gaining a single electron. The valency electron of Fluorine is 7 . It can easily attract 1 electron to it self to attain the octet rule. This is why most non metal in group 7 are very reactive .

Fluorine easily become an anion as they gain single electron. The charge become negatively charged. It gains single charge and possess a charge of -1.

The electronic configuration is 2 7. The atomic number of Florine is 9.
