THe atomic number would decrease by 2 as alpha particle comes out. But for two beta particles the atomic number would increase by 2. So the atomic number remains unchanged due to emission of one alpha followed by 2 beta particles.
protons, no. of protons is equal to the atomic number of an element.
Proton
The atomic number of an element is equal to the number of protons contained in the atomic nucleus.
The number of protons in the atomic nucleus determines what element it is. Each element has a unique number of protons, known as its atomic number.
The number of protons is equal to the atomic number of an atom
This particle is the proton, equal to the atomic number.
The number of neutrons.
The atomic number is determined by the number of protons, which are located in the nucleus.
no i cant answer it
The atomic number of an element is determined by the number of protons.
In a neutral atom, the number of protons (or the number of electrons) are the same as the atomic number.
The resulting element is protactinium, atomic number 91.
