None. Francium is highly reactive, and highly radioactive. It doesn't exist free in nature.
Francium is a true chemical element, not an example.
The Earth crust contain approx. 30 g francium.
For the most part none do. However, some ceramics contain uranium in their glazes and uranium may form francium as it decays. As a result, some plates may or may not contain an atom of francium at any given time.
None. Trust me on this one. Francium is one of the most ephemeral of elements, and is a "laboratory curiosity" for the most part.

Francium is a true chemical element, not an example.
As all chemical elements francium contain protons, neutrons and electrons.
As all chemical elements francium contain protons, neutrons and electrons.

It is estimated that the Earth crust contain approx. 30 g francium.
Yes. Earth's crust is estimated to contain about 30 grams of Francium at any given time.
For the most part none do. However, some ceramics contain uranium in their glazes and uranium may form francium as it decays. As a result, some plates may or may not contain an atom of francium at any given time.

Yes, francium is an alkali metal; the group contain lithium, sodium, potassium, caesium, rubidium and francium.
francium only has one valence electron (one electron in the outermost shell).
