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.
Type your answer here... the charge subatom particles is them
a light A photon is a massless particle.
There are three atomic particles with mass, the proton, neutron and electron. Of these three, the proton is the particle with a positive charge.
Atomic Mass
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.
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 number = number of protons mass number = number of protons + number of neutrons
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
This atomic particle is the neutron.
This atomic particle is the neutron.
Photons and neutrinos dont have mass.
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.
hydrogen
Electron
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
atomic mass unit
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.
A beta particle is an electron: the mass is 5.4857990946(22)×10−4amu.
The atomic number increases but the atomic mass stays the same after the emission of a beta particle by a radioactive atom.
