Read the wording for your board, then hide it and explain neutron emission in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Removing one neutron lowers the mass number by 1 while the proton number is unchanged, so charge stays the same.
A neutron may also be emitted, carrying a relative mass of 1 and no charge.
