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.

What two subatomic particles match the atomic number on the periodic table?
The two subatomic particles are protons and electrons. They match the atomic number on periodic table.
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 two subatomic particles are in the nucleus of the atom?
Proton and neutron.
What two subatomic particles are located at the nucleus of an atom?
Protons which possess a positive charge and neutrons which possess no electric charge are subatomic particles within the nuclei of atoms.
What two subatomic particles comprise the nucleus of a atom?
the you and the stupid! oh wait that is the same thing!
What two subatomic have about the same mass?
These particles are: proton and neutron.
What two subatomic participles have about the same mass?
These particles are: proton and neutron.
Is subatomic particles same as molar mass?
No. The two phrases have almost nothing to do with each other at all.
Which two particles in the atom have the same mass?
No two subatomic particles have the exact same mass. The proton and the neutron, however, come close. Neutrons are heavier than protons by only 2.3 X 10-30 kg.
Relation between subatomic particles and atomic mass unit?
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
The mass number is the sum of which two subatomic particles?
Neutrons and Protons.
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.
Which subatomic particles are used to determine an atoms mass number?
Two particles are considered. they are protons and nrutrons
Do nuetrons have higher mass or alpha particles?
alpha particles consist of two protons and two neutrons (helium nucleus) logically one neutron can not have a larger mass than two neutrons and two other subatomic particles of a similar mass
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.
Which two subatomic particles have the greastest mass?
protons and neutrons both are found inside the nucleus
