Actinium
225Ac--------alpha (4He) + 221Fr
Yes, francium can occur in a pure form, but it is extremely rare due to its high reactivity. Francium is a highly radioactive element that is typically produced in nuclear reactions and decays quickly into other elements.
Yes and no, alpha particles are a form or radiation (a helium nucleus), they are emitted from an unstable radioactive element which decays (and turns into some lighter element) by emitting the alpha particle. This form of decay is called alpha decay.
The chemistry of francium is not experimentally known; it is only estimated. Francium should be have properties similar to caesium.
helium does not combine with any element
No, helium inside a balloon is not a compound. Helium is a chemical element and is the second lightest element on the periodic table. It exists as individual helium atoms inside the balloon.

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.

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.
During each alpha decay, a helium nucleus (alpha particle) is emitted, decreasing the atomic number by 2 and the mass number by 4. Protactinium-229 undergoes two alpha decays to form Francium-221. The process of alpha decay involves the emission of alpha particles from the nucleus of an atom.
Helium is a gaseous chemical element.
Helium is an element because it contains only one atom in its simplest form.
Francium is a radioactive chemical element an can disintegrate.
The chemistry of francium is not experimentally known; it is only estimated. Francium should be have properties similar to caesium.
