Does subatomic particles have the smallest mass of any subatomic particle?
The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.
What is A subatomic particle that has no charge and very small mass is called?
Positron
Which subatomic particle can be described as having a relatively large mass?
Proton or neutron
What are the smallest of the three subatomic particles and are not counted in the mass of an atom?
electrons
How do you figure out the subatomic particle numbers for each element?
Number of protons= Atomic number Number of neutrons= Mass number-Atomic number Number of electrons=Number of protons (If there is no charge on the atom)
What subatomic particle has the less mass?
In the atom the electron is the lightest.
What subatomic particle Has the smallest relative mass?
In the atom the electron is the lightest.
Subatomic particle that has the least mass?
In the atom this particle is the electron. Generally in the particle physics: photons, gluons, neutrinos.
Which subatomic particle does not have a very big effect on the mass of the whole atom?
The electron.
What is a subatomic particles with almost no mass?
The electron is the lightest particle in the atom.
What is the subatomic particle that has the greatest mass?
The largest subatomic particle (by mass) is the proton. The mass of subatomic particles is measured in atomic mass units (amu). The proton has a mass of 1.007 amu, the neutron has a mass of 1 amu, and the electron has a mass of .0005 amu.
What subatomic particle or particles contributes the most to the mass of the atom?
These particles are protons and neutrons.
Why ins't the third subatomic particle counted in the mass of an atom?
Electrons have a mass of only about 0.0005 as much as protons or neutrons.
What particle have mass of lamu?
Subatomic particle
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.
Is hydrogen the smallest particle of an element?
An average hydrogen atom consists of 1 proton and 1 electron. The 1 proton accounts for nearly all of that atom's mass. The 1 electron has only about 1/2000th the mass of the proton. That's about 0.0005 of the total atomic mass.
What is a neutron in an atom?
The neutron is a subatomic particle with no net electric charge and a mass slightly larger than that of a proton.
