An alpha particle consists of 2 protons and 2 neutrons, so the atomic number would decrease by 2, and the weight by ~4. A beta particle is a high velocity electron emmitted from the decay of a neutron into a proton, so the atomic numkber would increase by 1, weight would remain unchanged.

When a nucleus emits an alpha particle, its Mass will decrease by 4 and its atomic number decreases by 2. This is because an alpha particle is equivalent to a helium-4 nucleus.
When a nucleus emits a beta particle, its atomic number will INCREASE by 1, since a beta particle has a negative charge.

when a nucleus emits alpha particle there is a decrease of 2 and the new element form is 2 places left in the periodic table.
when beta particle is emitted then there is an increase of 1 in atomic number n the new element moves to 1 place right in periodic table.
i hope it will help u.
