Beta particlesâ A beta particle is emitted during the radioactive decay of some unstable atoms. Beta particles can have either a negative charge or a positive charge and they have the same very small mass (1/2000 the mass of a neutron) regardless of charge.
An ion is a charged particle, such as Na+, the sodium ion. It has a positive charge, because it is missing one electron. Other ions, of course, are negatively charged. Cells have membranes that are made of lipid molecules (fats), and they prevent most things from entering or leaving the cell. But all over a cell membrane are proteins that stick out on both sides of the cell membrane. Some of these are ion channels.
