The mass of a neutron is approx 1837 times that of an electron. The mass of a proton is similar to that of a neutron. In the simplest atom, hydrogen, the mass of the nucleus is 1,837 times that of an electron. In the largest known atom, that of ununoctium, containing 281 baryons (neutrons or protons) the mass of the nucleus is approx 516,200 times that of an electron. So take your pick: 1,837 to 516,200.
There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.
Electron, proton, nucleus, atom
The vast majority of mass in an element is located in the nucleus, comprised of protons and neutrons. Electrons are considered to have almost no mass, although that they exist at all would imply that they must in fact have some mass.
slightly more than 14, carbon 12 has an atomic mass of 12 by definition, so 1 atomic mass = the sum of the mass of a proton neutron and electron divided by 2 neutrons are slightly heavier than the combined mass of an electron and proton carbon 14 has a higher percentage neutrons than carbon 12 so it is heavier relative to the number of particles in it's nucleus(14)
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.
The mass of the nucleus makes up most all of the mass of an atom. The only things outside the nucleus are the electrons. The mass of an electron is ~9.11E-31 kg. The mass of an electron is 1/1836 that of a proton.
This is because the mass of electron is without importance compared to the mass of protons and neutrons.
Compared to a proton, an electron has a much smaller mass (approximately 1/1836 times the mass of a proton) and a negative charge. Electrons are located outside the nucleus of an atom, while protons are found within the nucleus.
The bulk mass of an atom is concentrated in the nucleus, which contains protons and neutrons. Electrons, which have negligible mass compared to protons and neutrons, orbit around the nucleus in electron shells.
The subatomic particle that fits this description is the electron. Electrons have a negative charge, are found outside of the nucleus in electron shells, and have a very small mass compared to protons and neutrons.
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.
The nucleus by far.
Over 99% of the mass of an atom is contained in the nucleus, where protons and neutrons are located. Electrons, which have negligible mass compared to protons and neutrons, occupy the remaining space in the electron cloud surrounding the nucleus.
When a nucleus emits an electron (beta decay), the mass number stays the same because an electron has very little mass compared to a nucleon. However, the atomic number increases by one as a neutron is converted into a proton during the decay process.
An electron is not the largest part of an atom.An electron is the smallest component of an atom. Relatively, if a neutron or proton were 1 unit in size, an electron would be 1/1840 units in size. :3Read more: An_electron_is_the_largest_part_of_an_atom
The proton mass is about 2,000 times greater than the electron mass.
