Neither, fluorine is a pale yellow gas under standard conditions. The boiling point of fluorine is −188.11 °C so at room temperature fluorine will not be able to exhibit any hardness or softness since these terms don't apply to gases. Fluorine is very very reactive and is the most electronegative element in the Periodic Table.
Zinc is considered a hard metal; its hardness is similar to that of Iron.
Calcium is a relatively hard mineral with a Mohs hardness of 3. It is commonly found in bones and teeth, providing strength and structure to these tissues.
Sulfur is a brittle solid at room temperature, so it is not typically classified as either hard or soft. It has a low hardness compared to many metals and minerals, but it is not malleable like softer materials such as wax.
Chlorine was isolated before fluorine because it is more reactive and abundant, which made it easier to isolate and study. Fluorine is the most reactive of all elements and is rarely found in its elemental form in nature, making it more challenging to isolate.
Both fluorine and oxygen have high electronegativities due to their strong attraction for electrons. This is because they have incomplete outer electron shells, making them highly reactive in forming chemical bonds by attracting electrons. This makes them capable of pulling on shared electrons in a molecule.
No. Fluorine is a gas.
Fluorine gas is extremely damaging to the soft tissues of the respiratory tract.
That depends on the temperature and solid state phase. Fluorine solidifies at −220 °C (−363 °F) into a cubic structure, called "beta-fluorine". Beta-fluorine is soft - possibly owing to the generally disorganized arrangement of individual microscopic crystals. At −228 °C (−378 °F) fluorine undergoes a solid-solid phase transition to a monoclinic crystal structure called "alpha-fluorine". This phase is hard, with close-packed layers of molecules and a much more regular and extensive crystaline structure than beta-fluorine. Note that what we think we know about alpha-fluorine is based on work done by Nobel Laureate Linus Pauling and was quite tricky due to the very low temperatures required and the rather energetic reactions of fluorine with the materials usually used to hold chemicals.
Hard
it is hard and sometimes soft

soft you can bend and hard you can not
life's hard. Fluorine makes things harder. Brush your teeth with it.

Soft
"Treated wood can be soft or hard." But, generally what is bought from a lumberyard is soft.
Fluorine smells like Chlorine and Ozone, kinda, its hard to describe. I know, yum yum! :)
