∙ 10y agoAs Ra with atomic number radiates an alpha particle then the daughter nucleus will have it atomic number less by 2. So it would be 86. Hence the element is Radon

What element is formed when 60CO emits a beta particle?
When 60Co decays by beta- decay it produces 60Ni.
What happens to thorium when it emits an alpha particle?
Alpha emission means a He (A=4, Z=2) core is released along with energy. Helium's atomic number is 2 and the atomic mass is 4. So when Thorium (A=x, Z=90) emits an alpha particle it becomes a Radium (A=x-4, Z=88). By the way: Thorium is very vague when it comes to nuclear physics. It's important to state the atomic mass of the atom. There exist many forms of each element, called isotopes.
When a Uranium 238 emits an alpha particle the nucleus left behind has how many protons?
When a Uranium-238 emits an alpha particle, it loses 2 protons and 2 neutrons. The resulting nucleus, Thorium-234, has 90 protons.
When radium emits an alpha particle the resulting nucleus has atomic number?
When radium emits an alpha particle, the resulting nucleus has an atomic number that is 2 less and a mass number that is 4 less than the original radium nucleus.
To what does plutonium-239 decay when it loses an alpha particle?
When plutonium-239 loses an alpha particle through decay, it transforms into uranium-235.
What element does californium make when it emits an alpha particle?
Curium isotopes
What element does thorium-230 decay when it emits an alpha particle?
Thorium-230 decays into radium-226 when it emits an alpha particle.
What element does thorium 230 decay when it emits an alpha particle?
This isotope is radium-226.
What element does thorium become if it emits an alpha particle?
The nuclear reaction is: 232Th--------------- 228Ra + α
What happens to a radioactive nucleus when it emits alpha particle and What happens to a radioactive nucleus when it emits alpha particle?
dude..
If the isotope bismuth-213 emits an alpha particle two protons and two neutrons which element will be left over?
Lead-209 will be left over after the isotope bismuth-213 undergoes alpha decay, as the emission of an alpha particle causes the atomic number of the element to decrease by 2. Bismuth-213 has an atomic number of 83, so after the emission of an alpha particle (which has an atomic number of 2), the resulting element will have an atomic number of 81, which corresponds to lead.
What happens to the atomic number of an element if it emits 1 alpha particle and 1 beta particles?
It drops 2
What element is formed when 60CO emits a beta particle?
When 60Co decays by beta- decay it produces 60Ni.
What is lost from the nucleus of atom when it emits an alpha particle?
2 neutrons and 2 protons (this is what an alpha particle is made up of).
When radon undergoes natural transmutation reaction it emits?
alpha particle
What change in mass occurs when a radioactive atom emits an alpha particle?
4 from the alpha. Betas have negligible mass and gammas have no mass.
When radium atomic number 88 emits an alpha particle the resulting nucleus has atomic numbers?
226Ra------------alpha particle----------222Rn (radon, a radioactive gas)
