then we would never know about charge on it.
When a charged particle moves and experiences no magnetic force, it means that either the magnetic field is zero or the magnetic field is perpendicular to the velocity of the charged particle. As a result, the particle will only experience the electric force, causing it to follow a straight path according to the Lorentz force law.
A neutron is an electrically neutral subatomic particle found in the nucleus of an atom. It has a mass similar to that of a proton but carries no electrical charge. Neutrons play a crucial role in stabilizing the nucleus and are involved in nuclear reactions.

A)B-rays are the only type of radioactivity that is electrically charged. Alpha (a-rays) and gamma (y-rays) rays are both uncharged, or neutral, particles. B-rays, or beta particles, are high-energy electrons that are emitted from the nucleus of an atom and are the only type of radioactivity that is electrically charged.
Hydrogen ion.
There are many subatomic particles with negative charge, but the first negatively charged particle that anyone learns about is the electron. It is only invisible in the sense that humans can not see it because it is so small. It is a perfectly normal subatomic particle and certainly the most common negatively charged particle in the universe.
A positively charged nuclear particle is a proton. It is found in the nucleus of an atom and carries a positive electrical charge.
Protons are the only '+' particles in the (nucleus of an) atom.
A plasma may contain only electrically charged ions. A solution of an electrolyte in a solvent is also "filled with electrically charged ions" in the sense that such ions are present throughout the solution at the same density, but the solution also contains solvent and therefore is not filled with ions in the sense that nothing else is there.
The Earth's magnetic field, although it does not deflect all charged particles; it only deflects most of them.

An alpha particle is a helium nucleus, and as such it has 2 protons and 2 neutrons and no electrons. Thus, it is positively charged. This makes it very unlikely that it will hit the nucleus which is also positively charged and will repel the alpha particle. The only way to get the alpha particle to hit the nucleus is to accelerate it to very high speeds.
