All parts of the atom weigh something but when doing calculations electrons are said to have a mass of 0. This is because they actually have a mass of 1/1836 amu which is insignificantly small and so it is disregarded.

How does the mass number of an atom change when its nucleus absorbs a neutron?

Essentially the 3 basic parts to an atom are a Proton, Neutron and an Electron. Protons have a unit of mass and a positive charge Neutrons have a unit of mass and a neutral charge Electrons have no unit of mass and a negative charge. When a neutron breaks off from another atom it becomes a free radical that is then absorbed by the receiving atom because it would have a spare neutron space because the number of neutrons must be identical to the number of protons otherwise the atom will radioactivity decay. Essentially the mass number changes because the neutron has a mass.


How is the mass number different from the atomic number of an atom?

Atomic number of an element is the number of protons that an atom of an element contains. The atomic weight (the mass of the atom) is measured by not only the mass of the proton(s), but by the mass of the nuetrons and electrons too.


What number indicates the number of protons in the nucleus of an atom?

The atomic number tells you the number of protons in an atom. The atomic number is right above the element symbol. Example: 36 83.80 In this example, 36 is the atomic number, so the number of protons is 36. Protons and electrons can be found by the atomic number.


What does a neutron mean?

A neutron is a subatomic particle found in the nucleus of an atom. It has no electric charge and is about the same mass as a proton. Neutrons help stabilize the nucleus of an atom, preventing it from breaking apart.


What is the smallest part of an element that displays the chemical properties of an element?

An atom is the smallest part of an element that displays the chemical properties of that element. Each element is defined by the unique number of protons in its atom's nucleus, which determines its chemical behavior.

What part of the atom contains the majority of mass an atom has?

The nucleus contains the mass.


What is the part of the atom that makes up the mass of the atom?

the nucleus of the atom


How is the mass number related to an atom related to the number of neutrons?

The mass number is the total number of protons and neutrons in an atom's nucleus. The number of protons is the same as the element's atomic number, so the number of neutrons is the mass number minus the atomic number. The mass number can be determined by rounding the atomic weight to the nearest whole number. Also, the mass number is given as part of an isotope's name, for instance: Carbon-14 has a mass number of 14.


What part of an atom makes up the mass of an atom?

the nucleus


What is the smallest part of the atom that has almost no mass?

The smallest part of an atom would be a quark. Quarks are either up or down quarks, and have virtually no mass. Neutrinos have even less mass, but are not part of an atom.


What part of the atom does not add mass to it?

The electron.

What part of the atom is the heaviest has the most mass?

The nucleus of an atom is the heaviest part and contains most of the atom's mass. It is made up of protons and neutrons. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.


Which part of the atom does the atomic mass measure?

The Nucleus contains Protons and Neutrons which comprise practically all the atom's mass.


Made up of the protons and neutrons this part of the atom contains nearly all the mass of the atom?

The nucleus is the part of the atom made up of protons and neutrons, and it contains nearly all of the atom's mass. Electrons, which have much lesser mass, orbit around the nucleus.


What is the mass and volume of the nucleus?

The nucleus is a very small part of an atom, containing nearly all of its mass in a tiny volume. The mass of a nucleus depends on the number of protons and neutrons it contains, while its volume is estimated to be about 1 femtometer cubed, which is extremely small.
