What else can I help you with?
What are the smallest of the three subatomic particles and are not counted in the mass of an atom?
electrons
Does electron mean a subatomic particle with a negative charge?
Electrons are negatively charged subatomic particles, but have almost no mass. The mass of an electron is about 1/2000 that of a proton or neutron. The neutron is the most massive of the subatomic particles at 1.6755 x 10-24 grams.
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
Which subatomic particles have a mass so small it typically is ignored?
Electron
Which has the smallest mass?
Hydrogen has the smallest atomic mass at roughly 1.008 grams per mol (6.02x10^23 atoms)
Does a neutron have mass and if so, how does it compare to the mass of other subatomic particles?
Yes, a neutron has mass. The mass of a neutron is slightly greater than the mass of a proton, which is another subatomic particle found in the nucleus of an atom. Neutrons and protons are both much more massive than electrons, which are the smallest subatomic particles.
Where can you find the smallest subatomic particle?
This particle is the electron with a mass of 5,485 799 094 6(22)×10−4 amu.
Which subatomic particle has the smallest mass alpha particle neutron electron proton?
among these Electron has the least mass....
What subatomic particle Has the smallest relative mass?
In the atom the electron is the lightest.
What subatomic particle or particles contributes the most to the mass of the atom?
These particles are protons and neutrons.
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 term is used to define the way mass of subatomic particles is described?
Atomic Mass units
What series lists particles in order from the smallest to greatest mass?
Electron, proton, nucleus, atom
What are the smallest of the three subatomic particles and are not counted in the mass of an atom?
electrons
Which subatomic particle is least massive?
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.
Which of the subatomic particles has the smallest mass?
This particle is the electron: 9,10938291(40)×10−31 kg or 5,4857990946(22)×10−4 amu.
