Question

Fluorine (F) has seven electrons in its outermost shell. Fluorine _____.

Answer 1

2. F is non-metal, because it has seven electrons (more that 3)
3.It fills its shell by gaining one electron, because it is easier to gain 1 e⁻ than to loose 7 e⁻.
4. It becomes a negatively charged ion, because atom of F is neutral, it has "0" charge, and it takes one negatively charged electron(-1). (0 +(-1)= -1)

Answer 2

Answer:

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.
