calcium is not stable because the outer most atomic level is not full the only elements that are stable are the nobel gasses(helium,neon,argon,krypton,xenon,and radon)
Calcium carbonate makes limestone, while magnesium carbonate makes dolomite.
Because, due to the absorption of heat energy by the calcium atom in the flame. The electrons in the atom get promoted to a higher energy level, and exist in an unstable excited state. As they are unstable and prefer to be at their normal ground state, the extra energy that the electrons absorbed to be promoted in the first place is emitted in the form of a photon, light. The light emitted from the electrons of the calcium atoms will be at a specific wavelength, which is the red light you see emitted from the flame.

Your teeth do have calcium in them, but in a low concentration. If they were pure calcium, then the calcium would react with the air and saliva in you mouth and violently explode, shooting flames and most likely killing you.
CaCl2 + 2H2O so it makes Calcium chloride and water. ==
A copper atom can become unstable if it loses or gains electrons, leading to the formation of ions. Additionally, changes in its nuclear structure, such as gaining or losing protons, can also lead to instability. Physical factors, such as exposure to high-energy radiation, can also disrupt the stability of a copper atom.
Calcium is mostly stable
Alone, Calcium is actually extremely unstable and would be fatal if ingested.
it might not be unstable with anything.......
The hormone that makes a pregnant woman have their joints unstable is Relaxin.
no calcium no calcium
Calcium-40 is a stable isotope of calcium. It has 20 protons and 20 neutrons, giving it a balanced nuclear composition that is not prone to radioactive decay.
Yes. Yes it does.The element calcium has a known 24 Stable Isotopes. For more information, ask google
Noble gases have completely filled octet. It makes it difficult to get unstable.
