WebA "d" quark has a charge of -1/3 and an up has +2/3 which makes the neutron electrically neutral (-1/3+(-1/3)+2/3=0). In beta decay one of the "d"s is converted into a "u" and an electron is emitted in the process alongside an electron-antineutrino. In this way a new particle is created with three quarks: uud which happens to be a proton!

WebAlpha decay is a nuclear change process which produces an alpha particle. Alpha particles are He atoms which have had their electrons removed giving them a +2 charge.
