What is the new chemical identity of the radium atom after it has emitted an alpha particle?

The naturally occurring isotope of radium we encounter is radium-226. It appears in the decay chain of uranium. When radium-226 undergoes alpha decay, radon-222 is the result. The equation looks like this: 88226Ra => 24He + 86222Rn The 24He is the alpha particle, which is a helium nucleus.

Why do non-radioactive substances become radioactive when placed near a radium compound?
Radium, being radioactive, will irradiate and activate some things placed near a sample. The element radium in its "natural" form is an alpha particle emitter, and things that get hit by an alpha particle have a chance of undergoing nuclear transformation. An alpha particle, which is emitted by a 226Ra atom when it decays, is a helium-4 nucleus. It's composed of two protons and two neutrons. This is a "heavy hitter" as regards particulate radiation. It won't travel far, even in air, because it is too massive and it "runs into stuff" in scattering reactions because of its size. But when it reacts with a nucleus, things happen. That's how some materials near a radium source become radioactive.
Why does the radium glows in the dark?
i think it's because of this fluro chemical.
When radium emits an alpha particle the resulting nucleus has atomic number?
The result is radon, atomic number 86. 226Ra - alpha particle = 222Rn (radon, a radioactive gas)
What does radium feel like?
Radium is dangerous to feel but i'm assuming it feels smooth like a pebble
Is radium more powerful then a radioactive element?
Your question is meaningless. Radium IS a radioactive element, and its power depends on the context. If you mean "is there an element more radioactive than radium" then yes, there are many, e.g. astatine.
What radiations are emitted by radium and polonium?
Radium and polonium are principally alpha emitters.
What is the chemical symbol for radium?
The chemical symbol of radium is Ra.
What is the chemical symbol for a radium?
The chemical symbol of radium is Ra.
What is the chemical symbol of radium?
The chemical symbol of radium is Ra.
If radium 226 releases an alpha particle what is mass number of isotope formed?
Radium 226--------alpha particle-------- Radon 222
Why was radium used in luminous paint?
Alpha particles emitted by radium produce radioluminescence is zinc sulfide.
Chemical symbols for gold and radium?
Gold:- Au Radium:- Ra
After undergoing alpha decay an atom of radium -226 becomes?
Radium 226 decays by alpha emission to Radon 222. A helium nucleus is emitted by alpha emission which makes the mass reduce by 4 and its atomic number by 2.
What are the chemical properties of radium?
Ra is the chemical name. Radium reacts violently with water.
Is radium a compound or a element?
Radium is a chemical element, not a compound.
What is the sign for radium?
The chemical symbol of radium is Ra.
Is a radium a mixture?
Radium is a chemical element, not a mixture.
