help me with this How much does the mass and charge of a nucleus change when each type of radiation is emitted?

Part 1 of 2
positron

Change in mass
Change in charge

When a positron is emitted, the mass of the nucleus remains the same, as a positron has the same mass as an electron. However, the charge of the nucleus decreases by 1 unit, as a positron has a positive charge of +1.
