Protons and nuetrons Dom says: Protons and Neutrons.
The mass of protons and neutrons are very close but not identical.
In the atom the heaviest particle is the neutron but the proton is close.
Protons and neutrons are pretty close to the same mass.
protons and neutronsprotons are slightly lighter and have a + charge
Protons and neutrons.

THe electron!
It would depend on how much iodine is present. The greater the mass the more particles there would be
Subatomic particles with no charges are neutrons
These particles are called electrons, with a negative electrical charge and a very small mass.
Composite subatomic particles (such as protons or atomic nuclei) are bound states of two or more elementary particles. For example, a proton is made of two up quarks and one down quark, while the atomic nucleus of helium-4 is composed of two protons and two neutrons.
All subatomic particles have mass.
Proton and neutron (components of the atomic nucleus) have masses very close.
The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.
Subatomic particles have mass, dimensions, spin, sometimes have an electrical charge.
Mg+2 and Br-1
neutrons and protons
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
These particles are the protons and neutrons.
The neutron is the subatomic particle that has appreciable mass and lacks a charge.
Subatomic particles are the same size as basketballs.
The three main subatomic particles are the proton, neutron, and electron. Of these three, the electron has the least amount of mass at about 0.0005 amu or Atomic Mass units.
These particles are protons and neutrons.
