When uranium-238 atomic number 92 decays by emitting an alpha particle it becomes?
The atomic number will decrease by 2.
An alpha particle is a helium-4 nucleus, and it contains a pair of protons and a pair of neutrons. During alpha decay, an atomic nucleus has its Atomic Mass decrease by 4, and its atomic number decrease by 2.

What particle does argon 39 atomic number 18 emit when it decays to potassium 39 atomic number 19?
Argon-39 undergoes beta decay to become potassium-39, emitting an electron (beta particle) in the process. The atomic number increases by one due to the conversion of a neutron into a proton during beta decay.
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.
What is the alpha decay equation for polonium-218?
When a polonium-216 nucleus undergoes alpha decay, it will lose an alpha particle, which is made up of 2 protons and 2 neutrons. This means that polonium-216, which has an atomic mass of 216 and an atomic number of 84, will become the element with the atomic number of 82 (84 minus 2), and will have an atomic mass of 212 (216 minus 4). Lead has an atomic number of 82. So, this is how polonium-216 becomes an isotope of lead when it emits an alpha particle.
Why would an atomic nucleus give off a particle?
An atomic nucleus gives off a particle to become more stable and reach a lower energy state. This process is known as radioactive decay.
Each fundamental atomic particle has an opposite particle A collision of these opposites will result in the annihilation of each particle These types of particles are referred to as?
Anti-matter. Antimatter.
When radium-226 (atomic number 88) decays by emitting an alpha particle it becomes .?
?
Is radium identical to an alpha particle?
No. Radium is a heavy metal, atomic number 88 (with 88 protons). An alpha particle is a helium nucleus, atomic number 2. Radium decays by each atom emitting an alpha particle, becoming Radon gas, atomic nubmer 86.
What particle does argon 39 atomic number 18 emit when it decays to potassium 39 atomic number 19?
Argon-39 undergoes beta decay to become potassium-39, emitting an electron (beta particle) in the process. The atomic number increases by one due to the conversion of a neutron into a proton during beta decay.
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
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 is the atomic number of uranium 235 after it decays by emiting alpha particles?
After emitting an alpha particle, the atomic number of uranium-235 decreases by 2 since an alpha particle contains 2 protons. This means that the atomic number is reduced from 92 (uranium) to 90, resulting in the element thorium.
Which atomic particle has an atomic mass of one amu but no net charge?
This atomic particle is the neutron.
When an atom gives off a(an)..... It becomes an atom with an atomic number of two less?
An alpha particle, which is the nucleus of a helium atom.
What element does thorium 230 decay when it emits an alpha particle?
When thorium-230 decays by emitting an alpha particle, it transforms into radium-226. This decay process reduces the mass number by 4 and the atomic number by 2.
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.
An atomic particle that is positively charged?
This particle is the proton.
What atomic particle that is negatively charged?
This is the particle in an orbital in the space around the atoms nucleus and it is called an electron.
