Helium nucleus


What is the new element formed after the alpha decay occurred?

AlphaThe atomic number goes down by two and the atomic mass number goes down by four.Beta-The atomic number goes up by one and the atomic mass number stays the same.Beta+The atomic number goes down by one and the atomic mass number stays the same.


Do isotopes have the same atomic number and the same atomic mass?

No: They have the same atomic number but not the same atomic mass.


Do alpha prarticle share the same atomic number?

An alpha particle is, essentially, a helium nucleus.This means that is has the same atomic number (no. of protons) as Helium does - it just doesn't have the electrons as well.So the atomic number of an alpha particle would be 2.It's also not neutral, and would have a 2+ charge.The mass number of an alpha particle would be 4 as it has 2 neutrons and 2 protons.All alpha particles are helium nuclei, so they all share the same properties.


What happen to atomic number and mass number of nucleus when it emits alpha particle electron and proton?

It's been awhile for me, but this is how I remember it. It is not convenient for me to look it up right at the moment, so you may want to verify this. Emitting an alpha particle (2 proton 2 neutron), atomic number would decrease by 2 and atomic mass decreases by 4.Electron emission means a neutron turns into a proton and electron, but the electron shoots out. The atomic number increases by 1 and atomic mass stays the same. Proton emission, well it loses a proton. So the atomic number decreases and mass decreases.


Is the atomic number and atomic mass the same?

No, the atomic number is the amount of protons it has and the weight is its mass


How atomic number better than atomic mass?

No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.


Is the atomic number the same as atomic mass?

No.


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 particle consists of two protons and two neutrons it is the same as a helium nucleus release of a what particle by an atom decreases the atomic number by 2 and the mass number by 4?

The particle that consists of two protons and two neutrons, equivalent to a helium nucleus, is an alpha particle. When an atom releases an alpha particle, its atomic number decreases by 2 and its mass number decreases by 4.


Is the mass number the same as the atomic mass?

No, the mass number is not the same as the atomic mass. The mass number is the total number of protons and neutrons in an atom's nucleus, while the atomic mass is the average mass of all the isotopes of an element, taking into account their abundance.


Is atomic mass and molar mass similar and mass number of particles the same?

Atomic mass and molar mass are similar concepts but not the same. Atomic mass refers to the average mass of an atom of an element, while molar mass is the mass of one mole of a substance. The mass number of particles can be the same in certain cases, such as isotopes of the same element which have the same number of protons and different numbers of neutrons.
