No, fluorine is a diatomic gas at STP.
Gas
The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
Yes, fluorine does form monatomic anions with formula F-1.
Fluorine is a gas at STP. The density is (38 g / 22.4 L) x (1 pound / 454 g) = 0.00374 pounds / Liter
The gram formula mass of KF = 39.098 + 18.999 = 58.097. Therefore, 8.2 g of KF contains 8.2/58.097 = 0.141 mole of fluorine atoms. Each mole of F2 requires two fluorine atoms, so that 0.070 moles of fluorine gas will result. An ideal gas at stp occupies 22.4 liters per mole, so that the volume of gas produced will be about 0.070 X 22.4 = 1.6 liters to the justified number of significant figures, unless fluorine gas at stp deviates too much from ideality.
C. Helium is a monoatomic gas at STP.
Gas
The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
Yes, fluorine does form monatomic anions with formula F-1.
Fluorine can be in all 3 states of matter, however, at room temperature and normal pressure (STP) Fluorine is always in the gas form.It is a colourless (or pale yellow) gas existing as a diatomic molecules F2.
Since fluorine is a gas, it does not have malleability.

Looking at the atomic size,fluorine is the smallest of the halogen family.fluorine has an atomic number of 9 while iodine has its atomic mass to be 54.
No, F (fluorine) is is diatomic in its elemental form.
Fluorine and chlorine.
hydrogen, nitrogen, oxygen, fluorine, and chlorine are all gases at STP
