Francium is supposed to be very reactive but the chemistry of francium is not known.
Fluorine and francium are two elements that are never found as elements in nature due to their high reactivity. Fluorine readily reacts with almost all elements, while francium is extremely radioactive and decays quickly into other elements.
Zinc is usually combined with other elements.
magnesium :)
No, francium is not highly explosive. It is a highly reactive alkali metal that can react violently with water, but it does not exhibit explosive properties like some other elements. Francium is only found in trace amounts in nature due to its extreme rarity and radioactivity.
Francium (Fr) is a natural radioactive element, extremely rare.

The chemistry of francium is not known but francium is considered the most reactive metal.

Alkali metals are: lithium, sodium, potassium, rubidium, caesium and francium.

I suppose that the question refers to chemical elements and their natural state. Indeed, some elements cannot be found "alone" (i.e., not combined) in natural state. This applies to the most reactive elements, such as fluorine (gas), chlorine (gas), sodium (alkali metal), etc.
Francium is the element least likely to be found in nature in elemental form because it is highly radioactive and quickly decays into other elements. Its short half-life and rarity make it challenging to find naturally occurring samples of francium.
Yes, gold and silver are native elements, which means they can be found in their pure form in nature without being chemically combined with other elements.
Iodine is found in several other elements. Chlorine and Bromine are two examples, however it's important if mixing to know which to mix because of the reactive nature of the elements.
the majority of metals are found combined with other elements in nature. Only a few are found uncombined- the best known example is gold.
