What else can I help you with?
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?
The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
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 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 is the lightest subatomic particle of an atom?
electrons the smallest but weigh as much as protons neutrons weigh nothing ~Kay
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.
Which of the subatomic particle is the lightest?
Electron, lightest stable subatomic particle known. It carries a negative charge, which is considered the basic unit of electric charge. The rest mass of the electron is 9.109 × 10−31 kg, which is only 1/1,840the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton or a neutron, and the electron mass is not included in calculating the mass number of an atom.
How many subatomic particle would be present in an atom of helium with a mass of 4 amu?
6 subatomic particles. 2 protons and 2 neutrons (that accounts for the mass of 4 amu) as well as 2 electrons.
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.
