Next element in the Periodic Table ie Actinium.
When 60Co decays by beta- decay it produces 60Ni.
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, it loses 2 protons and 2 neutrons. The resulting nucleus, Thorium-234, has 90 protons.
The result is radon, atomic number 86. 226Ra - alpha particle = 222Rn (radon, a radioactive gas)
Yes, plutonium-239 emits alpha particles by decay.
When californium emits an alpha particle, it creates curium.
When an atom emits an alpha particle, it loses two protons and two neutrons from its nucleus. This results in a new element being formed with an atomic number that is two less than the original element.
Thorium-230 decays into radium-226 when it emits an alpha particle.
The nuclear reaction is: 232Th--------------- 228Ra + α
It drops 2
When 60Co decays by beta- decay it produces 60Ni.
When U-238 emits an alpha particle, it loses two protons. This results in the atom transforming into a different element (Th-234) which has two fewer protons in the nucleus.
In alpha decay, the parent element (nucleus) emits an alpha particle consisting of 2 protons and 2 neutrons. The daughter element is formed by subtracting the alpha particle from the parent element's atomic number and mass number. The daughter element is often located two positions to the left on the periodic table compared to the parent element.
a new element is formed
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.
You get this answer by performing the following: Mass # Mass # 4 Atomic # Parent symbol -> Atomic # Daughter symbol + 2 He 238 234 4 92 U -> 90 Th + 2 He Both sides must equal the same thing, so if you figure out what plus 4 = 238 and what plus 2 = 92, you can figure out the element is formed through decay. The resulting element in this case is Thorium.
This process is known as alpha decay. During alpha decay, an unstable atomic nucleus emits an alpha particle, which consists of two protons and two neutrons. This emission results in the transformation of the original nucleus into a new, lighter element with a lower atomic number.
