Hey! The excepted banacular is gay. Don't call them atoms that's just mean.

Which two subatomic particles make up most of the atoms mass?
It is usually considered to be neutrons and protons that hold most of an atom's mass, however there is one theoretical subatomic particle that is used to help explain mass, called the higgs boson particle.
What are protons and neutrons called?
They are called "subatomic particles." Another answerer suggested "nucleons," but this applies only to nuclear particles (protons and electrons). They are also Fermions, but there are fermions other than these three. I would stick with "subatomic particles."
How many total number of particles present in one atom?
The answer depends on the atom! The total number of subatomic particles in an atom of an isotope is the sum of the mass number and the atomic number of the isotope; the mass number counts the protons and neutrons together, and the atomic number recounts the number of protons, which in a neutral atom must be the same as the number of protons.
What is a similarity between a proton and an electron?
electrons are on the outside and don't count as part of the atomic mass. Protons do count as part of the mass and are inside the atom.
What are the three sub atomic particles?
The three subatomic particles in an atom are protons, neutrons, and electrons:Protons have a relative mass of 1 and a charge of +1, and they are found in the nucleus of an atom.Neutrons have a relative mass of 1 and no charge, and they are also found in the nucleus of an atom.Electrons have a relative mass of 1/1836 and a charge of -1. They are found in specific orbits around the nucleus and are held in these orbits by the positive charge of the protons in the nucleus.
Which subatomic particles has the lest mass?
In the atom the electron is the lightest.
What do the three of the subatomic particles have in common?
They have a mass and are components of the atom.
What subatomic particle or particles contributes the most to the mass of the atom?
These particles are protons and neutrons.
How do you calculate subatomic particles in isotopes?
mass #= # of protons + # of neutrons
What are the smallest of the three subatomic particles and are not counted in the mass of an atom?
electrons
What are the two principal components of the nucleus of the atom?
The two principal components of an atom at a subatomic level are Protons and Neutrons. Protons are subatomic particles with a mass of 1 and a charge of 1+ Neutrons are subatomic particles with a mass of 1 and a charge of 0 or neutral
What are the two subatomic particles with a mass?
In the atom, protons and neutrons; the mass of the electron is very small.
What is a subatomic particles with almost no mass?
The electron is the lightest particle in the atom.
What are the subatomic particles with no mass called?
All subatomic particles have mass.
Subatomic particles responsible for most of an atom's mass?
Protons and neutrons.
How many subatomic particle would be present in an atom of helium with a mass of 4 amu?
An atom of helium with a mass of 4 atomic mass units (amu) would typically contain 4 subatomic particles. Two of these particles would be protons, two would be neutrons, and two would be electrons.
What are the relative atomic mass of subatomic particles in atom?
neutrons are heavier than protons by a bit more than the mass of electron.
