Neutron. A proton is positively charged, an electron is
negatively charged, and a neutron has no charge and so it is
neutral, hence the name. There's thoughts that it has no charge
because it's actually made up of a proton and an electron, so a
plus charge and negative charge would cancel out, leaving it
neutral.
The particle you are referring to is likely a proton. Protons are subatomic particles found in the nucleus of an atom and have a positive electrical charge. They also have mass, although their mass is much smaller than everyday objects.
A particle that has a large mass and a positive charge is known as an alpha particle. These particles contain 2 protons and 2 neutrons which are bound together to form an identical particle to a helium nucleus.
The mass number is the total number of protons and neutrons in an atom's nucleus, while the atomic number is the number of protons in the nucleus. The mass number determines the atom's mass, while the atomic number determines the element's identity on the periodic table.
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
Atomic Mass
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
This atomic particle is the neutron.
A neutron is the subatomic particle with a charge of 0 and a mass of 1 atomic mass unit.
Photons and neutrinos dont have mass.
This atomic particle is the neutron.
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.
Electron
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
atomic mass unit
A beta particle is an electron: the mass is 5.4857990946(22)×10−4amu.
An alpha particle is a positively charged nuclear particle consisting of two protons bound to two neutrons. The atomic number of an atom decreases by 2 and the mass number decreases by approximately 4 when an alpha particle is ejected.
