The mass does not change much. The Atomic number will increase though.

What does An alpha particle has the same mass and atomic number as?
Helium nucleus
When an unstable nucleus produces an alpha particle by how many units does the atomic number of the nucleus change?
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
Nucleus of the chemical element atomic number 2 emitted by some radioactive substances?
alpha particle, He nucleus
How is the atomic number of a nucleus change is it by alpha decay or beta decay or gamma decay?
Alpha decay decreases the atomic number by two. Beta- decay increases the atomic number by one. Beta+ decay decreases the atomic number by one. Gamma decay does not change the atomic number. However, gamma decay is often incidental to a precipitating alpha or beta event that upsets the energy equilibrium in the nucleus, so the two are not unrelated.
What type of nuclear reaction results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus?
This is emission of an alpha particle which is a helium nucleus. Thus the atomic number decreases by two and the atomic weight by four, in such a radioactive decay
An alpha has the same mass and atomic number as an?
A+. . .. . . . helium nucleus
If a radioactive nucleus with an atomic number of 88 emits an alpha particle what will the atomic number of the new nucleus be?
Two less, since the alpha particle takes away two protons.

When radium atomic number 88 emits an alpha particle the resulting nucleus has atomic numbers?
226Ra------------alpha particle----------222Rn (radon, a radioactive gas)

In alpha decay is the atomic number of the daughter nucleus equal to the atomic number of the isotope undergoing decay?
No, it is 2 smaller as two protons go to form the alpha particle.
When thorium decays by emmitting an alpha particle what is the atomic number of the resulting nucleus?
88Ra, Radium
What is the effect on the mass number and change of a nucleus when it loses alpha particles?
The mass number goes down by 4, and the atomic number goes down by 2 when a nucleus loses an alpha particle. XYZ --> alpha emission --> X-2Y-4Q + 24He2+
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.
