Why do you only include the mass of the protons and neutrons in the nucleus?

The mass of protons and nuetrons make up the nucleus. The electrons are outside the nucleus in the electron cloud. Electrons have virtually no mass and are similar to a wave form.

The mass number of an elements is equal to?
the total number of protons and neutrons in the nucleus.
Is the difference between the mass number of an isotope and its atomic number is equal to the number of nucleons in the nucleus?
It is equal to the number of neutrons in the nucleus, not nucleons (which include both protons and neutrons.)
Total number of particles in the nucleus is called what?
There are two types of particles in the nucleus of an atom, which are the Protons and the Neutrons. The number of particles in the nucleus depends what is the element. For example, Oxygen has 8 protons and 8 neutrons in the nucleus and Phosphorus has 15 protons and 16 neutrons in the nucleus.
How is an atomic number similar to mass number?
The nucleus of an atom consists of protons and neutrons. The number of protons in a particular nucleus is its "atomic number". The total number of protons and neutrons in a particular nucleus is its "mass number".
What is located in a atom's nucleus?
The nucleus of an atom contains neutrons and protons. Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus. Because the nucleus is only made up of protons and neutrons, it is positively charged.
Is mass located in an atom's nucleus or in its protons?
The mass of an atom is concentrated in the nucleus, which is made up of protons and neutrons.
What is the atomic mass of atoms made of?
The Atomic Mass is made up of protons and neutrons (which is basically the nucleus.)
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
What Make up nearly all of an atoms mass?
The sum of all protons and neutrons - Apex Learning
The nucleus of an atom contains what two particles?
nucleus....contains protons & neutrons
The mass number of an elements is equal to?
the total number of protons and neutrons in the nucleus.
What has the same mass of a proton?
Neutrons have the same mass as that of a proton. Neutrons and protons are present in the nucleus
Where is most of the atoms mass found?
An atom's mass is concentrated in its nucleus, which is located in the center of the atom. Protons and neutrons within the nucleus are responsible for its mass; the electrons, which are located outside of the nucleus, don't contribute to the mass of the atom.
Where are protons found in the nucleus of an atom?
Protons, and neutrons make up the nucleus of an atom. The nucleus is the centre of an atom where most of the mass is found. Protons are positively charged, neutrons have no charge.
Mass number of nucleus?
The Mass Number is the number of protons plus the number of neutrons in the nucleus.
What contributes to the mass of the atom?
number of protons and number of neutrons
Is the difference between the mass number of an isotope and its atomic number is equal to the number of nucleons in the nucleus?
It is equal to the number of neutrons in the nucleus, not nucleons (which include both protons and neutrons.)
