What else can I help you with?
Which subatomic particle has such a small mass that is not used to calculate the atoms atomic mass?
electron
Where is most of potassium atoms mass located?
Most of the mass of a potassium atom is located in its nucleus, which contains protons and neutrons. The electrons in the electron cloud surrounding the nucleus have significantly less mass compared to the nucleus.
What does the atomic mass of an electron represent?
The mass of an electron is atomic mass units is 5,485 799 090 70(16); the mass of the electron is not an atomic mass.
Why is the mass of an atoms electrons not included in the atoms mass number?
Mass number is defined as the number of protons and neutrons. It is related to Atomic Mass which incudes electron mass and nuclear binding energy , (binding energy reduces the overall mass relative to the combined masses of the protons and neutrons.) Electron mass is not included as mass number is element specific wheras the count of electrons varies depending on the chemical state. The mass of electrons is negligible compared to the mass of the protons and neutrons, binding energy is a larger effect.
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
Which particle has the smallest mass atoms or electron?
An electron has a much smaller mass than any atom.
Which component of an atom does not add to the atoms mass?
electron
Which subatomic particle has such a small mass that is not used to calculate the atoms atomic mass?
electron
How many atoms have in atomic mass number?
The atomic mass number represents the total number of protons and neutrons in the nucleus of an atom. It does not include the number of electrons, which are found in the electron cloud surrounding the nucleus.
Why the effective mass of an electron is different than it mass in vacuum?
The effective mass of an electron in a material is different from its mass in vacuum because in a material, the electron interacts with the surrounding atoms and lattice structure, causing its motion to be influenced by these interactions. This results in an effective mass that can be greater or lesser than the electron's mass in vacuum.
Is the Mass of hydrogen atom is about the same as a proton?
Yes, in general. All hydrogen atoms contain one proton, most with no neutrons and all neutral atoms with one electron - and the electron has a much smaller mass. Some hydrogen atoms contain one (or, rarely, two) neutrons and so are heavier. But on average the atom has a mass much the same as a proton.
How does Relativity explain an electron's mass seeing that an electron doesn't take up any space?
its because i really dont know
What the smallest particle in a atom?
Size on the scale of atoms is very hard to define. The electron has zero mass. Quarks have varying amounts of mass.
Which has the smallest mass?
Hydrogen has the smallest atomic mass at roughly 1.008 grams per mol (6.02x10^23 atoms)
What mass of sodium metals contains the same number of atoms as 12.00g of carbon?
i dont know the answer
Where is most of potassium atoms mass located?
Most of the mass of a potassium atom is located in its nucleus, which contains protons and neutrons. The electrons in the electron cloud surrounding the nucleus have significantly less mass compared to the nucleus.
