Write nuclear equations for: Lanthanum-144 becomes Cerium-144 when it undergoes a beta decay.
Neptunium-233 is formed when Americium-237 undergoes a beta decay.
When Proctactinium-229 goes through two alpha decays, Francium-221 is formed.
Uranium-238 undergoes an alpha decay and produces two gamma rays.
The Neon-22 nucleus is formed when an element undergoes a beta decay.
Samarium-146 is produced when an element undergoes an alpha decay.
The beta decay of Dysprosium-165 creates a new element.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
