No nuclear particle has a relative mass of 4. However, the alpha particle which is emitted by one of the radioactive iodine isotopes, has a relative mass of 4. An alpha particle is emitted from the nucleus but not referred to as a nuclear particle because it is made up of 4 nuclear particles - 2 neutrons and 2 protons.
The electron has a neglible mass and a charge of minus 1.602 x 10-19 Coulombs.
The number in a nuclear chemical symbol represents the charge of the particle is the atomic number or the number of protons in the nucleus.
The Neutron
no its charge is -1
The chaarge of an alpha particle is +2.
The nuclear particle that has no charge is the neutron.
No, that would be a neutron. A proton is a nuclear particle with a mass of 1 AMU and a 1+ charge
The electron has a neglible mass and a charge of minus 1.602 x 10-19 Coulombs.
Proton
The number in a nuclear chemical symbol represents the charge of the particle is the atomic number or the number of protons in the nucleus.
The electric charge of an alpha particle is positive. An alpha particle is a helium nucleus (which being a nucleus has a positive charge)
Neutron
Nuetron.
The Neutron
The charge of a triplet of strange quarks would be -⅓ times 3, which is -1. This is because each strange quark has an electric charge of -⅓.
An alpha particle has a charge of 2, which means it is positively charged.
Gamma rays do not have mass or charge, so they do not contribute to the balance of a nuclear equation that involves the emission of an alpha particle. The alpha particle carries away the mass and charge necessary to balance the nuclear equation.
